SimpactTM : General characteristics
Function of LV Switchgear
National and international standards define the manner in which electric
circuits of LV installations must be realised, and the capabilities and limitations
of the various switching devices which are collectively referred to as switchgear.
Selection of a MCCB.
The choice of a MCCB is made in terms of :
n Electrical characteristics of the installation
Icc
Fault current limitation technology:
The fault-current limitation of a MCCB concerns its ability, more or less Prospective
fault-current peak
effective, in preventing the passage of the maximum prospective fault-
current, permitting only a limited amount of fault current to flow.
Advantages Prospective
Limited fault-current peak
n Current-limiting MCCB strongly attenuate all harmful effects associated

with short-circuit currents
Limited
n Reduction of thermal effects: Conductors heating is significantly reduced, current

1 Circuit breaker (IEC 60947-2) "Mechanical switching device, capable of making, carrying and breaking
currents under normal circuit conditions and also making, carrying for
a specified time and breaking currents under specified abnormal circuit
conditions such as those of short circuit. Circuit breakers are the device
of choice for protection against overloads and short-circuits"
2 Rated current (In) This is the current that the device can carry continuously with the
contacts closed and without abnormal temperature rise.
3 Rated impulse withstand voltage (Uimp) The peak value of an impulse voltage of prescribed form and polarity
which the equipment is capable of withstanding without failure under
specified conditions of test and to which the values of the clearances
are referred. The rated impulse withstand voltage of an equipment
shall be equal to or higher than the values stated for the transient
overvoltages occurring in the circuit in which the equipment is fitted.
4 Rated insulation voltage (Ui) The rated insulation voltage of an equipment is the value of voltage
to which dielectric tests and creepage distances are referred. In no
case shall the maximum value of the rated operational voltage exceed
that of the rated insulation voltage.
5 Rated operational voltage (Ue) "A value of voltage which, combined with a rated operational current,
determines the application of the equipment and to which the relevant
tests and the utilisation categories are referred. For multipole equipment,
it is generally stated as the voltage between phases." This is the
maximum continuous voltage at which the equipment may be used.
7 Making capacity Icm Value of prospective making current that a switching device is capable
of making at a stated voltage under prescribed conditions of use and
behaviour. Reference is generally made to the short-circuit making
capacity Icm.
8 Ultimate breaking capacity (Icu) "Expressed in kA, it indicates the maximum breaking capacity of the
circuit breaker. It is confirmed by a test with one opening and one
closing/opening at Icu, followed by a check that the circuit is properly
isolated. This test ensures user safety."
9 Service breaking capacity (Ics) "Expressed as a percentage of Icu, it provides an indication on the
Protocol / Internet Protocol) robustness of the device under severe conditions. It is confirmed by
a test with one opening and one closing/opening at Ics, followed by
a check that the device operates correctly at its rated current, i.e. 50
cycles at In, where temperature rise remains within tolerances and the protection system suffers no damage."

10 Degree of protection (IP) IEC 60529 "Defines device protection against the penetration of solid objects and
liquids, using two digits specified in standard IEC 60259. Each digit
corresponds to a level of protection, where 0 indicates no protection."
First digit (0 to 6): protection against penetration of solid foreign
objects. "1 corresponds to protection against objects with a diameter
> 50 mm, 6 corresponds to total protection against dust." Second digit (0 to 8): protection
against penetration of liquids (water). "1 corresponds to protection against falling drops of water
(condensation),"
8 corresponds to continuous immersion.
11 Ethernet TCP/IP (Transmission Control Ethernet is a very common network protocol and complies with IEEE
standard 802.3. Ethernet TCP/IP is the protocol that brings web
functions to Ethernet networks. Most PCs have an Ethernet 10/100
card (10 or 100 Mbit/s) for connection to the internet.
12 Electrical durability IEC 60947-1 "With respect to its resistance to electrical wear, equipment is
characterised by the number of on-load operating cycles, corresponding
to the service conditions given in the relevant product standard, which
can be made without replacement."
