Selection Diagram for Capacitors, Power Factor Correction Units and Filter Circuits
Power factor correction is the switching of capacitors in parallel with inductive linear or non-linear loads in the network. The decisive factors in the selection of power factor correction are the network conditions and the load structure.

n Networks conditions It is essential to consider any harmonic content that is present, both in the low-voltage network and in the higher-level mediumvoltage network. AF ripple control systems that are present must also be taken into account in the selection of power factor correction. n Load structure If the proportion of nonlinear loads (e.g. converter drives) in the low-voltage network is 20 % of the preceding transformer apparent power rating Sr, then 4RF capacitors with reactors should be chosen.

Definitions
n Branch
A branch is the capacitor rating switched from a controller output.
With most controllers this response value must be calculated and set on the controller during set-up. The SIMEAS C controllers determine the C/k value automatically and no controller settings need to be carried out by the person setting up the controller (self-adaptation to C/k value).
EN 60831-1, section 4 states that any capacitor bank or battery must be discharged within three minutes from its initial peak voltage to 75 V or less. However, capacitors always have to be discharged to 10% of the rated voltage before being switched in again. In automatically controlled P.F.C. circuits the capacitor must be discharged within a few seconds, because the controller can, due to a changing load, issue a switch-in signal for the same capacitor after only a short delay, switching in the capacitor which has been just switched off. The discharge time in P.F. correction units must always therefore be less than the controller response time .
n Capacitance stability
Capacitance stability means conformance to the electrical data over the whole service life of the capacitor. This is especially very important with detuned and tuned filter circuits. Permanent conformance to the tuning frequency is only possible with filter circuits if the loss of capacitance in the capacitors due to ageing is extremely low.
n Power capacitors
Power capacitors are usually three-phase capacitors with a high capacitance rating and conform to EN 60831-1, IEC 831-1. They are used exclusively for phase shifting. Power capacitors feature n high capacitance stability and long service life n internal protection system n high pulse withstand capability. These characteristics are especially important in reactor connected applications. Linear loads When connected to a sinusoidal system voltage, linear loads draw a sinusoidal current which may be phase shifted with respect to the voltage. Examples of linear loads are: Three-phase motors, Capacitors, Filament lamps, Resistor heating.
n Impedance factor
For a customers system this is the ratio of the audio frequency impedance to the network frequency impedance. In contrast to the blocking factor, the impedance factor takes into account the influence of the ratings of the network transformer and the P.F. correction system. The ratio of transformer power rating to the P.F. correction power rating mainly determines the interference effects on the audiofrequency ripple control signals. If the P.F. correction power rating is low compared to the transformer power rating, then impermissible interference on the audio-frequency ripple control signals should not be expected.
n Harmonic filtering
Harmonic currents can cause critical interference in power systems. With the employment of capacitors with reactors the interference is mitigated or even completely removed. The degree of harmonic filtering achieved is dependent on the design and configuration of the filter circuit reactors and capacitors. The reactor/capacitor ratio p is a characteristic of the degree of harmonic filtering. The degree of harmonic filtering increases as p decreases.
n Discharge device,
discharge time Discharge devices are used to discharge capacitors after disconnection from the network. This means that they must be able to dissipate the energy
1 We = CU 2 2 stored in the capacitor within a few seconds. Suitable discharge devices are resistors and reactors. Due to their high AC inductance, discharge reactors produce very low losses at system frequency.
n Response time
The response time of the controller is the time period for which a signal (reactive power requirement) must be applied in order to produce a switching command from the controller.
n Impulse withstand capability Capacitors used in automatic power factor correction units and which are therefore subject to frequent switching, require high impulse withstand capability, because the high inrush current stresses the capacitor windings as well as the switching devices (see precharging resistors).
n Motor capacitors
Motor capacitors are singlephase capacitors and conform to DIN VDE 0560 Part 8. They are generally of low capacitance rating and are designed for starting or running motors. In contrast to power capacitors motor capacitors have: n no protection system n lower capacitance stability and a shorter service life n lower impulse withstand capability. If required, single-phase motor capacitors can be connected to form three-phase units.
n C/k value
The C/k value is the response value of a P.F. controller. It is given by the capacitor rating C of the first branch circuit and the C.T. ratio k.

Definitions
n Non-linear loads
On application of a sinusoidal system voltage, non-linear loads draw a non-sinusoidal current from the network. Examples of non-linear loads are: n Variable-speed drives, n Frequency converters, n Uninterruptible power supplies, n Dimmers, television sets, n Devices with saturated magnetic circuits, n Fluorescent lamps, n Arc furnaces, welding equipment n Semiconductors (diodes and thyristors).
n Resonance effect
In compensated AC power systems a special case may occur in which the inductive and capacitive impedances cancel each other. Since with the voltage applied only a relatively low ohmic resistance acts to limit the current, high current spikes occur which can even cause the tripping of overcurrent protection devices.
n Number of steps
The number of steps is defined by the step function ratio. The number of steps is calculated by adding the numbers in the step function ratio. For example, for the step function ratio 1:1:2:2:3, the number of steps would be 9. In order to obtain a sufficiently accurate control and also to prevent too frequent switching, a number of steps between 5 and 12 is recommended. A large number of steps does not result in a significant improvement of the power factor.
n Resonance frequency
At the resonance frequency fR the reactances XL and XC of a series oscillating circuit are equal and opposite and thus cancel each other (XL = XC ). Therefore, the impedance of the oscillating circuit is practically zero at the resonance frequency since only the relatively small ohmic component is active.
fR = f1
n Harmonics
Non-linear loads draw a non-linear current from the network. This non-sinusoidal current can be broken down using Fourier analysis into a fundamental wave with frequency f1 and superimposed harmonics with frequencies f = f1 .
fR = 50
1 0.07
= 189 Hz
The ordinal number is a parameter describing the harmonics. It represents the ratio of the harmonic frequency to the system frequency. = 5 indicates the 5th harmonic with the frequency f = f1. At f1 = 50 Hz, f5 = 250 Hz. At f1 = 60 Hz, f5 = 300 Hz. The amplitude of the harmonic currents decreases with the increase in the ordinal number referred to the fundamental wave.
1 l = l1
n Ordinal number
n Blocking factor af
This is the ratio of the audio frequency impedance ZfT for a system (e.g. capacitor with AF blocking device or capacitor with reactors) to the reactance XC of the capacitor at the system frequency f1 (e.g. 50 Hz).
e.g.: l5 =
1 l1 5
n SIPCON T
SIPCON = Siemens Power Conditioning. This includes components and complete systems which, when connected to the power system, produce substantial improvements in the power system quality. SIPCON T (Traditional Compensation) provides a decisive contribution to power system quality using power factor correction and harmonic filtering.

Description
n Field of application
4RB5 power capacitors are used in fixed compensation units and in power factor correction units. Capacitors for power factor correction without reactors should only be used for power systems where the converter load is less than 20 % of the total load. Capacitors in the ISO protective housing can be connected directly at the load as fixed compensation units. Capacitors for power factor correction with reactors should be used with reactors for power systems where the converter load is greater than 20 %.

n Design
The metal coatings of 4RB5 MKK power capacitors are vapour deposited on a polypropylene foil. The foil acts as the substrate as well as the dielectric. The capacitors are filled with a protective gas and are therefore dry-type capacitors. The capacitors are self-healing. They are protected against impermissibly high overloads by means of an internal overpressure cut-off. When this protection trips, the capacitor housing extends by about 10 mm in the direction of the terminals. An appropriate safety distance to neighbouring components or housing parts should be allow-ed.

Description
n Field of application
4RY small power factor correction units are used for centralized power factor correction of inductive loads in power systems without or with a converter load less than 20 % of the total load.
Technical data
Standards Current carrying capacity EN 60439-1, EN 60831-1, IEC 439-1 Irms = 1.3 x IN (includes: UN + 10 %, CN + 10 % and any harmonic content present) + 10 % approx. 1 W/kvar - 20 to + 35 C, 24 h average short-term + 40 C RAL 7032 up to 3000 m above sea level, above 3000 m on request see selection and ordering data see page 14/2 Icf = 65 kA fuse type Siemens NH-gl/gG or equivalent
Permissible voltage increase over 8 h daily Power loss within the systems Ambient temperature
small power factor correction units 4RY16 and 4RY19/29 small power factor correction units are mounted on base plates with dry power capacitors, with capacitor contactors and a discharge device. The base plate is built into a sheet-steel or moulded-plastic housing. 4RY36 and 4RY39/49 small power factor correction units are constructionally identical and they also contain an AF blocking device. The power factor correction unit and AF blocking device are built into a suitable sheet-steel or moulded-plastic housing.
Degree of protection Connecting cable and back-up fuses Rated short-circuit current Icf for protection by back-up fuses or integral LV HRC fuses
n Connection
Connection to the power system is made using cables. Each power factor correction unit contains appropriate cable terminals. The connection of the current transformer leads is made to the transformer terminals.
K_086.eps
n Operating principle
The power factor controller measures the reactive power present and, when deviations from the setpoint occur, it issues switching commands to contactors. These switch capacitor branches in or out depending on the requirements. The capacitors are discharged within a few seconds after switching off. For 4RY small power factor correction units the controller BLR CC is used, see page 13/1.

Important note: Power factor correction units with AF blocking circuits are only designed for power systems with low harmonic content. The harmonic voltages u5 and u7 must not exceed 3 %, respectively 2 %, because otherwise resonances within the AF blocking circuits will cause overloads.
As an alternative to AF blocking, power factor correction units with reactors (7 % or 14 %) can be used. See selection diagram on page 1/4 for the selection of power factor correction units with regard to AF ripple control.
Ordering note -Z Y01 + plain text of existing audio frequency These details are needed because the AF blocking is designed exactly according to the audio frequency present.

4RY Power Factor Correction Units without Reactors > 50 to 500 kvar per Cabinet
with or without built-in AF blocking device Description
n Field of application
4RY18/28 power factor correction units without reactors and ready for connection are used in low-voltage power systems with low harmonic content, corresponding to a proportion of non-linear load less than 20 % of the upstream transformer rated power. Similarly, the harmonic content of the higher level medium-voltage network should be taken into account because capacitors without reactors can, related to the medium-voltage network, form a series resonant circuit with the network transformer. If its resonant frequency is located in the vicinity of a low frequency harmonic, network disturbances can be created under some circumstances. 4RY18/28 power factor correction units can be supplied for almost all system voltages occurring throughout the world.

n Design
The 4RY18/28 units with 75 kvar to 150 kvar are installed on base plates in sheet-steel housings. The degree of protection for the housing can be taken from the selection and ordering data. The 4RY18/28 units greater than 150 kvar are installed with 4RY56 modules, see page 6/2, in sheet-steel cabinets with ventilation slots and natural cooling. The 4RY38/48 units are constructionally identical to the 4RY18/28 units, but also contain an AF parallel blocking circuit. The degree of protection can be taken from the selection and ordering data. The SIMEAS C controller, see page 12/2, is installed as the power factor controller.
n Operating principle
The power factor controller measures the inductive reactive power present in the network and also the corresponding power factor. It compares this with the set target cos and switches capacitors in or out as required using the contactors in the capacitor modules. The SIMEAS C controller automatically determines the capacitor ratings connected to its outputs and immediately switches in the capacitor rating which best corresponds to the requirements. This method optimizes the number of switchings.
n Connection
The connection to the power system is made using cables. Each P.F. correction unit contains appropriate cable terminals. The connection of the current transformer leads is made using the transformer terminals provided.

Important note: Power factor correction units without reactors and with AF blokking circuits are only designed for power systems with low harmonic content. The harmonic voltages u5 and u7 must not exceed 3 %, respectively 2 %, because otherwise resonances within the AF blocking circuits will cause overloads. As an alternative to AF blocking, power factor correction units with reactors (7 % or 14 %) can be used in networks with AF ripple control. See selection diagram on page 1/4 for the selection of power factor correction units with regard to AF ripple control.

Description
n Field of application
4RY56 capacitor modules without reactors are employed for forming power factor correction units without reactors. The modules are suitable for use in low-voltage networks with a low harmonic content, corresponding to a proportion of non-linear load less than 20 % of the upstream transformer rated power. Similarly, the harmonic content of the higher level medium-voltage network should be taken into account because capacitors without reactors can, related to the mediumvoltage network, form a series resonant circuit with the network transformer. If its resonant frequency is located in the vicinity of a low frequency harmonic, network disturbances can be created under some circumstances.
The module width for 600 mm cabinet width is 580 mm. Normally, the supporting pillars included in the cabinet system can be used. The module width for 800 mm cabinet width is 720 mm. This means that the modules can pass through the cabinet door opening without any problem, but the mounting panel width must be taken into account when selecting the supporting pillars. If required, supporting pillars for certain types of cabinet can be supplied with the modules on request, see Accessories on page 13/2.

n Electrical connections
On the power side the 4RY56 modules are connected together via the busbar system at the front. The busbars are constructed such that no extra connecting lugs are required. One 4RY56 module per section contains special busbar sections which are suitable for accepting the connecting cables. The connection of the 4RY56 module on the control side to the power factor controller and to the control voltage is provided by control lines which should be routed in a suitable manner (e.g. cable ducts).
n Design
The 4RY56 modules on a galvanized sheet-steel chassis are fitted with dry-type 4RB5 MKK power capacitors with capacitor contactors and with discharge devices for the fast discharge of the capacitors (4EJ99 discharge reactors or resistors). For connecting the modules together and for the connection to the power system via cable, each 4RY56 module has a 60 mm busbar adapter system with copper bars E-Cu 30 x 10 mm mounted at the front.
n Mounting information
The mounting holes on the 4RY56 modules are universally suitable for 20 mm and 25 mm pitch. The 25 mm pitch of the Siemens 8MC cabinet series with alternative square and round holes with thread entries for self-tapping screws are ideal for mounting modules. The 4RY56 modules are simply suspended on these supporting pillars and mounted with self-tapping screws. See page 5/2 for complete units formed from 4RY56 modules.

4RF1 Power Factor Correction Units with Reactors 4RF2 Extension Units
Description
n Field of application
4RF1/2 power factor correction units with reactors are supplied ready for connection for use in low-voltage power systems with high harmonic content corresponding to a proportion of non-linear load greater than 20 % of the upstream transformer rated power. The tuned frequencies of the compensation system with reactors are below the 5th harmonic. So capacitors with reactors always have an inductive impedance with regard to harmonics. Resonance problems, which can occur with compensation systems without reactors in power systems containing harmonics, are improbable in this case. Apart from capacitive reactive power, power factor correction units with reactors also provide filtering of low frequency current harmonics. The lower the level of reactor/ capacitor ratio p in %, the greater is the filtering of the 5th and 7th current harmonics. If present however, AF ripple frequency levels less than 350 Hz are also reduced. In order to prevent impermissible interferences, the selection of the power factor correction unit with reactors should be carried out according to page 1/4 taking into consideration existing audio frequencies. The selection tables also contain information about application in power systems with AF ripple control.
n Design
The 4RF1/2 units with ratings up to 75 kvar are mounted on base plates in sheet-steel housings. The degree of protection for the housings can be taken from the selection and ordering data. The 4RF1/2 units with ratings greater than 75 kvar are formed using 4RF5 modules (see page 9/2) in sheet-steel cabinets with ventilation slots and natural cooling. For 250 kvar per 600 mm section and 400 kvar per 800 mm section an additional fan module is installed. The degree of protection for the housings can be taken from the selection and order-ing data. The SIMEAS C controller is installed as the power factor controller, see page 12/2.

n Operating principle
The power factor controller measures the inductive reactive power present in the network and also the corresponding power factor. It compares this with the set target cos and switches capacitors in or out as required using the contactors in the capacitor modules. The SIMEAS C controller automatically determines the capacitor ratings connected to its outputs and immediately switches in the capacitor rating which best corresponds to the requirements. This method optimizes the number of switchings. Connection The connection to the power system is made using cables. Each P.F. correction unit contains appropriate cable terminals. The connection of the current transformer leads is made using the transformer terminals provided.

4RF3 Power Factor Correction Units with Special Reactor Connected Capacitors, 4RF4 Extension Units
with AF blocking < 250 Hz and simultaneous high harmonic filtering Description
n Field of application
4RF3/4 power factor correction units with special reactor connected capacitors are ready for connection and for use in low-voltage power systems with a high proportion of harmonics where the nonlinear load may be greater than 20 % of the upstream transformer rated power. The tuned frequencies of the compensation system with reactors are below the 5th harmonic. Thus capacitors with reactors always have an inductive impedance with regard to harmonics. Resonance problems which can occur with compensation systems without reactors in power systems containing harmonics are improbable in this case. Apart from capacitive reactive power, 4RF3/4 power factor correction units with reactors also provide filtering of low frequency current harmonics. Due to the special reactor connection, which is either a parallel circuit of various reactors and capacitors or a combination of reactors and capacitors with an AF parallel blocking device, adequate blocking of AF frequencies below 250 Hz is obtained despite high filtering of the 5th and 7th harmonics. The selection tables contain information about application in power systems where AF ripple control is in operation. The 4RF3/4 units are available from ratings 200 kvar upwards, because the required high harmonic filtering only becomes relevant from an appropriate capacitor rating. If the required capacitor rating is less than 200 kvar, then 4RF19 power factor correction units with reactors (14 %) should be selected, see page 7/10.
Design The 4RF3/4 units are built up from 4RF5 modules (see page 9/2) in a sheet-steel cabinet with ventilation slots and natural cooling. A fan module is needed from 400 kvar per section. The degree of protection for the housings can be taken from the selection tables. The SIMEAS C controller is built in as the power factor controller, see page 12/2. When reactor connected in combination (parallel circuit of various capacitors with reactors), the 4RF34/44 units can provide power ratings up to 400 kvar per section. Depending on the audio frequency present, the 4RF36/46 units have 7 % or 8 % reactor/ capacitor ratio with a built-in AF parallel blocking device. Power ratings up to 300 kvar per section are possible. Operating principle The power factor controller measures the inductive reactive power present in the network and also the corresponding power factor. It compares this with the set target power factor and switches capacitors in or out as required using the contactors in the capacitor modules. The SIMEAS C controller automatically determines the capacitor ratings connected to its outputs and immediately switches in the capacitor rating which best corresponds to the requirements. This method optimizes the number of switchings. Connection The connection to the power system is made using cables. Each P.F.C. unit contains appropriate cable terminals. The connection of the current transformer leads is made using the transformer terminals provided.

Description
n Field of application
4RF5.. capacitor modules with reactors are employed for forming power factor correction units with reactors. The modules are suitable for use in low-voltage power systems with a high harmonic content, corresponding to a proportion of non-linear load > 20 % of the upstream transformer rated power.
n Design
The 4RF5.. modules on a galvanized sheet-steel chassis are fitted with dry-type 4RB5 MKK power capacitors with capacitor contactors or 3TF contactors and with discharge devices for the fast discharge of the capacitors (4EJ99 discharge reactors or resistors). For connecting the modules together and for the connection to the power system via cable, each 4RF5.. module has a 60 mm busbar adapter system with copper bars E-Cu 30 x 10 mm mounted at the front. The module construction is identical for 4RF56 p = 5.67 % 4RF57 p = 7 % 4RF58 p = 8 % 4RF59 p = 14 % 4RF53 with combined reactors.
The 4RF5.. modules are simply inserted into the section on these drawer brackets and mounted on the supporting pillar with self-tapping screws. See page 7/5 onwards for complete units formed from 4RF5 modules. The module width for 600 mm cabinet width is 536 mm. The module width for 800 mm cabinet width is 720 mm. Therefore, the modules can be passed without problem through the cabinet door opening, but the width of the base plates should be taken into account when selecting the supporting pillars. Where required, supporting pillars for certain cabinet types can also be supplied on request, see Accessories on page 13/2.

On the power side the 4RF5.. modules are connected via the busbar system at the front. The module busbars are connected using extra copper connecting lugs E-Cu 30 x 10 mm. Under Accessories on page 13/2 copper connecting lugs are available. For other lengths the copper connecting lugs must be provided by the customer. One 4RF5.. module per section includes special busbar parts suitable for terminating the connecting cables. On the control side the 4RF5.. module connection to the power factor controller and to the control voltage is provided by control lines which are to be suitably laid (e.g. in cable ducts) by the customer.
n Mounting information
K_106.eps
K_107.eps
The mounting holes on the 4RF5.. modules are universally suitable for 20 mm and 25 mm pitch. In Siemens power factor correction units supporting pillars with 20 mm pitch and thread entries for selftapping screws are used. Two drawer brackets which must be first mounted on the supporting pillar are used with each 4RF5.. module.

4RF14 tuned filter circuits are used in systems with a converter load > 50 % of the total load or if the local power supply utility requires filtering of self-generated harmonics. Up to 90 % of the 5th, 7th, 11th and 13th harmonics are filtered. The filter circuits can only be combined with power factor correction units with reactor connected capacitors.
Design Filter circuit units are supplied ready for connection in sheetsteel cabinets with ventilation slots and degree of protection IP20. If required, they can be combined from separate filter circuits which are designed for the filtering of the 5th, 7th, 11th and 13th harmonics. Depending on the rating they consist of one or several branches. The individual branches comprise: n Fuse switch-disconnector with fuse monitoring n LV HRC fuses for short-circuit protection n A contactor for switching the branch n A filter reactor with thermal overload protection n Low-loss MKV power capacitors (technical data on request) n Discharge reactors for quick discharge The following standard branches are available:

n Operating principle
The branches can be switched manually or via a central control command. An electrical interlock only enables the branches for the higher order harmonics to be switched in when those for the lower order harmonics have already been switched in circuit. Filter circuits compensate the inductive reactive power with their capacitor rating, but they are not controllable. If an improvement in the power factor, cos , is also desired, power factor correction units with reactors can be connected in parallel.

Furthermore, the harmonic content of the higher level network and the short-circuit reactance at the connection point must be known. In order to specify a filter circuit suitable for operation, an enquiry is required giving details of the power system conditions. If necessary, the harmonics must be measured, see Catalog SR 10.2 in the catalog index on pages 14/6 and 14/7.

n Connection
Operating principle The SIMEAS C power factor controller has six output relays. With these relays up to six capacitor branches can be controlled in any step function ratio. The switching state is then shown on the display. With a deviation of the power factor cos and at 60 % of the rating of the first capacitor, the capacitor required for the correction is computed and the appropriate branch switched in. The controller has the task of switching all branches, as far as possible, with equal frequency. The controller operates with time delays of 30 seconds on switching in and 3 seconds when switching off, as set ex-works. As with the discharge time, both times can be parameterized via the optical interface. Switching in occurs only after the discharge period has expired which is set to 30 seconds. With the SIMEAS C power factor controller there is a choice of the following four operating modes: n Display: Automatic mode with display of the measured values n Manual: Manual mode n Input 1 2 3 4: Input mode n Error: (View/delete error message) The operating mode is changed by simultaneously pressing the plus and minus key.

n Design
The 4RY66 modules on a galvanized sheet-steel chassis are fitted with an MCCB (Moulded-Case Circuit-Breaker) and a control terminal strip. Controller modules with built-in fan assembly also contain three fans and a bimetallic thermostat.
n Mounting information
The mounting holes on the 4RY66 modules are universally suitable for 20 mm and 25 mm pitch. The 4RY66 modules are mounted on the supporting pillar using self-tapping screws. The module width for 600 mm cabinet width is 536 mm or alternatively 580 mm. The module width for 800 mm cabinet width is 720 mm. Therefore, the modules pass without difficulty through the cabinet door opening, but the base plate width should be taken into account when selecting the supporting pillars. If required, supporting pillars for certain cabinet types can be supplied on request, see Accessories on page 13/2.
n Electrical connections
Connection to the external power system conductors L1, L2 and L3 is made via the MCCB. L1 provides the supply voltage for the controller and the control voltage for the controller outputs. L2 and L3 provide the measurement voltage for the controller (please refer to the operating instructions for the controller). All contactors in the power factor correction unit are connected to the control terminal strip in the controller module. Connection of the power factor controller, mounted in the cabinet door, is made via a multi-pole numbered control cable. A control transformer must be employed for system voltages > 415 V without external control voltage supply, see Accessories, page 13/2.

Note:
The built-in fan assembly is controlled via a bimetallic thermostat arranged on the controller module. Its trip value is continuously adjustable up to +60C. The airflow is directed upwards and aids the extraction of the dissipated heat below and above the controller module. The cabinet roof should contain ventilation slots. Only use 4RX98.. fan assemblies; please refer to the Accessories on page 13/2
The supply voltage for the power factor controller and the fans is 230 V 50/60 Hz. 1) A control transformer is needed, see Accessories on page 13/2, if the control voltage is not provided externally. The MCCB (Moulded-Case Circuit-Breaker) is a miniature circuit-breaker serving as the short-circuit protective device for the measurement and supply voltage of the controller and for the control voltage of the controller outputs.

Discharge reactors satisfy the requirements for permanently connected discharge devices as well as providing discharge times of just a few seconds. The 4EJ99 discharge reactor produces only extremely low losses due to its high resistance on alternating current. When the capacitors are switched off, very quick discharge is provided by the low ohmic resistance of about 5 k.

Degrees of protection IP provided by the enclosure Degrees of protection for power factor correction Power factor correction units which are designed as lowvoltage switching device combinations as per EN 60439 Part 1, DIN VDE 0660 Part 500, IEC 439-1, must be equipped with at least degree of protection IP2X. This does not apply to units on mounting plates or modules intended for installation in existing enclosures. Detailed information on IP degrees of protection provided by the enclosure can be found in DIN VDE 0470 Part 1, EN 60529. Power factor correction units and fixed compensation units in this catalog are equipped with IP20, IP22D, IP40, IP54 and IP65 degrees of protection. The units are constructed in such a way that, at an ambient temperature of + 35 C (mean value over a period of 24 h), the temperature limits are not exceeded without auxiliary cooling. Degrees of protection higher than those provided in this catalog require special design. The capacitor rating in each enclosure must either be reduced or auxiliary cooling (fan or heat exchanger) must be implemented. For this reason, degrees of protection higher than those specified in this catalog should only be requested if this is absolutely essential at the site at which the units are installed due to ambient conditions or for safety reasons.
Protection IP20
First digit Safe to touch and protection against solid foreign bodies 12.5 mm diameter is ensured. Safe to touch and protection against solid foreign bodies 12.5 mm diameter is ensured.
Supplementary letter

Protection against vertical dripping water, even if the enclosure is tilted by up to 15 on both sides of the vertical. No protection against water1).
IP40
Protection against access to dangerous parts with 1 mm wire and protection against solid foreign bodies 1mm diameter is ensured. Protection against access to dangerous parts with a 1 mm wire and against dust is ensured. Protection against access to dangerous parts with a 1 mm wire is ensured and the enclosure is dust-tight.
IP54
IP65
Designation The degree of protection provided by the enclosure is designated by the IP code which comprises 2 digits and 2 optional letters (additional letter and complementary letter). The first digit designates the electric-shock hazard protection and the protection against ingress of solid foreign bodies. The second digit designates the protection against the ingress of water. The additional letter denotes the degree of protection with regard to exposure to dangerous parts; the complementary letter indicates the additional qualities for water and weather protection (not relevant for power factor correction). The table above provides an overview of the degrees of protection specified in this catalog.
1) Certain protection against vertical dripping water is already provided as all enclosures have IP20 and IP40 by means of a raised roof. Under certain circumstances, however, splashes from dripping water may penetrate the inside of the cabinet. 2) The degree of protection IP22D is implemented as follows: Ventilation slots in the door covered with 1 mm protection grid, slots in roof covered with 10 mm protection grid and prod-proof roof metal design. This promotes heat dissipation through the cabinet roof. Foreign bodies > 1 mm can only penetrate the cabinet roof if they enter the unit from the bottom to the top through the roof metal construction. The first digit here is 2 for this reason only. The degree of protection IP22D therefore is the optimum solution for most installation sites with regard to heat dissipation and degree of protection.

Maximum permissible voltages on 4RB power capacitors Continuous voltages Power capacitors must be suitable for operation with the voltages specified in the adjacent table. The overvoltage values which are permissible without noticeable damage to the capacitor depend on their duration, frequency with which they occur, and the capacitor temperature. It is assumed that the overvoltages in the table which are higher than 1.15 times UN occur 200 times throughout the operating time of the capacitor.

Voltage increase at low load (for power factor correction units, the capacitors are switched off by the controller in this case)
Such that the capacitor current does not exceed 1.5 times the rated capacitor current.
Note: In systems without reactors, the rated voltage UN of the capacitor can always coincide with the rated voltage of the system in which the capacitor is operated. It is not necessary to use 4RB capacitors with a higher rated voltage UN (e.g. 415 V AC or 440 V AC) in a system with a certain rated voltage (e.g. 400 V AC 50 Hz).
In systems with reactors, the voltage increase which occurs at the capacitor terminals as a result of connecting the reactor and capacitor in series must be considered. The voltage Uc at the capacitor terminals is calculated using the formula:
Uc =
Un 1 p
400 V = 430 V 1 007 .
e.g. Uc =
p = reactor/capacitor ratio e.g. 0.07 for 7 % Un = system voltage e.g. 400 V AC.
