Compliance with standards

Compact NS circuit breakers and auxiliaries comply with the following: b international recommendations: v IEC 60947-1 - general rules v IEC 60947-2 - circuit breakers v IEC 60947-3 - switches, disconnectors, switch-disconnectors, etc. v IEC 60947-4 - contactors and motor starters v IEC 60947-5.1 and following - control circuit devices and switching elements; automatic control components b European (EN 60947-1 and EN 60947-2) and the corresponding national standards: v France NF v Germany VDE v U.K. BS v Australia AS v Italy CEI b the specifications of the marine classification companies (Veritas, Lloyds Register of Shipping, Det Norske Veritas, etc.) b French standard NF C 79-130 and the recommendations issued by the CNOMO organisation for the protection of machine tools. For U.S. UL, Canadian CSA, Mexican NOM and Japanese JIS standards, please consult us.
Standardised characteristics indicated on the rating plate: Ui: rated insulation voltage Uimp: rated impulse withstand voltage Icu: ultimate breaking capacity, for various values of the rated operational voltage Ue cat: utilisation category Icw: rated short-time withstand current Ics: service breaking capacity In: rated current suitable for isolation
Pollution degree
Compact NS circuit breakers are certified for operation in pollution-degree 3 environments as defined by IEC standard 60947 (industrial environments).
Tropicalisation
Compact NS circuit breakers have successfully passed the tests prescribed by the following standards for extreme atmospheric conditions: b IEC 60068-2-1 - dry cold (-55 C) b IEC 60068-2-2 - dry heat (+85 C) b IEC 60068-2-30 - damp heat (95 % relative humidity at 55 C) b IEC 60068-2-52 - salt mist (severity level 2).
Environmental protection
Compact NS circuit breakers take into account important concerns for environmental protection. Most components are recyclable and the parts of Compact NS630b to NS3200 circuit breakers are marked as specified in applicable standards.
Ambient temperature
b Compact NS circuit breakers may be used between -25 C and +70 C. For temperatures higher than 40 C (65 C for circuit breakers used to protect motor feeders), devices must be derated as indicated in the documentation. b circuit-breakers should be put into service under normal ambient operatingtemperature conditions. Exceptionally, the circuit breaker may be put into service when the ambient temperature is between -35 C and -25 C. the permiss ble storage-temperature range for Compact NS circuit breakers in the original packing is -50 C (1) to +85 C.
Discrimination
As standard, the Compact NS range ensures discrimination between two circuit breakers positioned in series in an installation.

Positive contact indication
All Compact NS circuit breakers are suitable for isolation as defined in IEC standard 60947-2: b the isolation position corresponds to the O (OFF) position b the operating handle cannot indicate the OFF position unless the contacts are effectively open b padlocks may not be installed unless the contacts are open. Installation of a rotary handle or a motor mechanism does not alter the reliability of the position-indication system. The isolation function is certified by tests guaranteeing: b the mechanical reliability of the position indication system b the absence of leakage currents b overvoltage withstand capacity between upstream and downstream connections.
E18569
Installation in class II switchboards

All Compact NS circuit breakers are class II front face devices. They may be installed through the door of class II switchboards (as per IEC standard 60664), without downgrading switchboard insulation. Installation requires no special operations, even when the circuit breaker is equipped with a rotary handle or a motor mechanism.
Degree of protection
As per standards IEC 60529 (IP degree of protection) and EN 50102 (IK degree of protection against external mechanical impacts).

STR trip units for Compact NS400 to 630
12481
Compact NS400 to 630 circuit breakers, types N, H and L, 3-pole and 4-pole, may be equipped with any of the STR23SE, STR23SV, STR53UE and STR53SV electronic trip units. The STR53UE and STR53SV trip units offer a wider range of settings and the STR53UE offers a number of optional protection, measurement and communications functions.

Standard protection with selectivity Protection of systems supplied by generators. Protection of long cables
Protection of systems with an overloaded neutral Protection of systems U > 525 V
Selection of the trip unit depends on the type of distribution system protected and the operational voltage of the circuit breaker. Protection for all types of circuits, from 60 to 630 A, is possible with only five trip-unit catalogue numbers, whatever the circuit-breaker operational voltage: b U y 525 V: STR23SE, STR23SE OSN or STR53UE b U > 525 V: STR23SV or STR53SV. Trip units do not have a predefined rating. The tripping threshold depends on the circuit breaker rating and the LT (long time) current setting. For example, for an STR23SE trip unit set to the maximum value, the tripping threshold is: v 250 A, when installed on a Compact NS400 250 A v 630 A, when installed on a Compact NS630.

Setting example
What is the overload-protection threshold of a Compact NS400 circuit breaker equipped with an STR23SE (or STR23SV) trip unit set to Io = 0.5 and Ir = 0.8 ? Answer. In x Io x Ir = 400 x 0.5 x 0.8 = 160 A. The identical trip unit, with identical settings but installed on a Compact NS630 circuit breaker, will have an overload-protection threshold of: 630 x 0.5 x 0.8 = 250 A.

Ammeter (I)
A digital display continuously indicates the current of the phase with the greatest load. The value of each current (I1, I2, I3, Ineutral) may be successively displayed by pressing a scroll button. LEDs indicate the phase for which the current is displayed. Ammeter display limits: b minimum current u 0.2 x In. Lower currents are not displayed b maximum current y 10 x In.
Zone selective interlocking (ZSI)

A number of circuit breakers are interconnected one after another by a pilot wire. In the event of a short-time or earth fault: b if a given STR53UE trip unit detects the fault, it informs the upstream circuit breaker, which applies the set time delay b if the STR53UE trip unit does not detect the fault, the upstream circuit breaker trips after its shortest time delay. In this manner, the fault is cleared rapidly by the nearest circuit breaker. The thermal stresses on the circuits are minimised and time discrimination is maintained throughout the installation. The STR53UE trip unit can handle only the downstream end of a zone selective interlocking function.Consequently,the ZSI option cannot be implemented between two Compact NS circuit breakers equipped with STRE53UE trip units. The ZSI option of the STR53UE trip unit operates only with an upstream circuit breaker equipped with a Micrologic A, P control unit. Opto-electronic outputs Using opto-transistors, these outputs ensure total isolation between the internal circuits of the trip unit and the circuits wired by the user.
Communications option (COM)

This option transmits data to Digipact distribution monitoring and control modules. Transmitted data: b settings b phase and neutral currents (rms values) b highest current of the three phases b overload-condition alarm b cause of tripping (overload, short-circuit, etc.).

Overload alarm
A yellow alarm LED goes on when the current exceeds the long-time trip threshold. Micrologic A control units measure the true (rms) value of currents. They provide continuous current measurements from 0.2 to 20 In and are accurate to within 1.5 % (including the sensors). A digital LCD screen continuously displays the most heavily loaded phase (Imax) or displays the I1, I2, I3, IN, Ig,In, stored-current (maximeter) and setting values by successively pressing the navigation button. The optional external power supply makes it poss ble to display currents < 20 % In. Below 0.05 In, measurements are not significant. Between 0.05 and 0.2 In, accuracy is to within 0.5 % In + 1.5 % of the reading.

Micrologic control units

Micrologic P "power" for Compact NS630b to 1600
Protection settings
12481
Micrologic P control units include all the functions offered by Micrologic A. In addition, they measure voltages and calculate power and energy values. They also offer new protection functions based on currents, voltages, frequency and power reinforce load protection in real time.
The adjustable protection functions are identical to those of Micrologic A (overloads, short-circuits, earth-fault and earth-leakage protection). Fine adjustment Within the range determined by the adjustment dial, fine adjustment of thresholds (to within one ampere) and time delays (to within one second) is poss ble on the keypad or remotely using the COM option. IDMTL (Inverse Definite Minimum Time Lag) setting Coordination with fuse-type or medium-voltage protection systems is optimised by adjusting the slope of the overload-protection curve. This setting also ensures better operation of this protection function with certain loads.
DB101485
Neutral protection On three-pole circuit breakers, neutral protection may be set using the keypad or remotely using the COM option, to one of four positions: neutral unprotected (4P 3d), neutral protection at 0.5 Ir (4P 3d + N/2), neutral protection at Ir (4P 4d) and neutral protection at 1,6 Ir (4P 3d + 1,6N). Neutral protection at 1,6 Ir is used when the neutral conductor is twice the size of the phase conductors (major load imbalance, high level of third order harmonics). On four-pole circuit breakers, neutral protection may be set using a three-position switch or the keypad: neutral unprotected (4P 3d), neutral protection at 0.5 Ir (4P 3d + N/2), neutral protection at Ir (4P 4d). Neutral protection produces no effect if the long-time curve is set to one of the IDMTL protection settings.
Programmable alarms and other protection

Depending on the thresholds and time delays set using the keypad or remotely using the COM option, the Micrologic P control unit monitors currents and voltage, power, frequency and the phase sequence. Each threshold overrun is signalled remotely via the COM option. Each threshold overrun may be combined with tripping (protection) or an indication carried out by an optional M6C programmable contact (alarm), or both (protection and alarm).
Load shedding and reconnection

Load shedding and reconnection parameters may be set according to the power or the current flowing through the circuit breaker. Load shedding is carried out by a supervisor via the COM option or by an M6C programmable contact.
Measurements
The Micrologic P control unit calculates in real time all the electrical values (V, A, W, VAR, VA, Wh, VARh, VAh, Hz), power factors and cos j factors. The Micrologic P control unit also calculates demand current and demand power over an adjustable time period. Each measurement is associated with a minimeter and a maximeter. In the event of tripping on a fault, the interrupted current is stored. The optional external power supply makes it possible to display the value with the circuit breaker open or not supplied.
Histories and maintenance indicators
The last ten trips and alarms are recorded in two separate history files. Maintenance indications (contact wear, operation cycles, etc.) are recorded for local access.

The M6C (six contacts) auxiliary contacts may be used to signal threshold overruns or status changes. They can be programmed using the keypad on the Micrologic P control unit or remotely using the COM option.
Communication option (COM)

The communication option may be used to: b remotely read and set parameters for the protection functions b transmit all the calculated indicators and measurements b signal the causes of tripping and alarms b consult the history files and the maintenance-indicator register. b maximeter reset. An event log and a maintenance register, stored in control-unit memory but not available locally, may be accessed in addition via the COM option.
Note: Micrologic P control units come with a non-transparent lead-seal cover as standard.

Navigation from one display to another is intuitive. The six buttons on the keypad provide access to the menus and easy selection of values. When the setting cover is closed, the keypad may no longer be used to access the protection settings, but still provides access to the displays for measurements, histories, indicators, etc.

Demand metering The demand is calculated over a fixed or sliding time window that may be programmed from 5 to 60 minutes. According to the contract signed with the power supplier, an indicator associated with a load shedding function makes it possible to avoid or minimise the costs of overrunning the subscribed power. Maximum demand values are systematically stored and time stamped (maximeter). Currents

Additional technical characteristics

Setting the display language System messages may be displayed in six different languages. The desired language is selected via the keypad. Protection functions All current-based protection functions require no auxiliary source. Voltage-based protection functions are connected to AC power via a voltage measurement input built into the circuit breaker. Measurement functions Measurement functions are independent of the protection functions. The high-accuracy measurement module operates independently of the protection module, while remaining synchronised with protection events. Measurement-calculation mode b measurement functions implement the new "zero blind time" concept which consists in continuously measuring signals at a high sampling rate. The traditional "blind window" used to process samples no longer exists. This method ensures accurate energy calculations even for highly variable loads (welding machines, robots, etc.) b energies are calculated on the basis of the instantaneous power values, in two manners: v the traditional mode where only positive (consumed) energies are considered v the signed mode where the positive (consumed) and negative (supplied) energies are considered separately. Accuracy of measurements (including sensors) b voltage (V) 0.5 % b current (A) 1.5 % b frequency (Hz) 0.1 % b power (W) and energy (Wh) 2 %. Stored information The fine setting adjustments, the last 100 events and the maintenance register remain in the control-unit memory even when power is lost. Time-stamping Time-stamping is activated as soon as time is set manually or by a supervisor. No external power supply module is required (max. drift of 1 hour per year). Reset An individual reset, via the keypad or remotely, acts on alarms, minimum and maximum data, peak values, the counters and the indicators.

Reflex tripping
Compact NS100 to 630 devices incorporate the exclusive reflex-tripping system. This system breaks very high fault currents by mechanically tripping the device via a "piston" actuated directly by the pressure produced in the breaking units resulting from a short-circuit. For high short-circuits, this system provides a faster break and a trip guarantee, as well as natural total discrimination. Reflex-tripping curves are exclusively a function of the circuit-breaker rating.
