标准简介：This standard applies to circuit-breakers, the main contacts of which are intended to be
connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.;
it also contains additional requirements for integrally fused circuit-breakers.
It applies whatever the rated currents, the method of construction or the proposed applications
of the circuit-breakers may be.
The requirements for circuit-breakers which are also intended to provide earth-leakage
protection are contained in Annex B.
The additional requirements for circuit-breakers with electronic over-current protection are
contained in Annex F.
The additional requirements for circuit-breakers for IT systems are contained in Annex H.
The requirements and test methods for electromagnetic compatibility of circuit-breakers are
contained in Annex J.
The requirements for circuit-breakers not fulfilling the requirements for over-current protection
are contained in Annex L.
The requirements for modular residual current devices (without integral current breaking
device) are contained in Annex M.
The requirements and test methods for electromagnetic compatibility of circuit-breaker
auxiliaries are contained in Annex N.
Supplementary requirements for circuit-breakers used as direct-on-line starters are given in
IEC 60947-4-1, applicable to low-voltage contactors and starters.
The requirements for circuit-breakers for the protection of wiring installations in buildings and
similar applications, and designed for use by uninstructed persons, are contained in
IEC 60898.
The requirements for circuit-breakers for equipment (for example electrical appliances) are
contained in IEC 60934.
For certain specific applications (for example traction, rolling mills, marine service) particular or
additional requirements may be necessary.
NOTE Circuit-breakers which are dealt with in this standard may be provided with devices for automatic opening
under predetermined conditions other than those of over-current and undervoltage as, for example, reversal of
power or current. This standard does not deal with the verification of operation under such pre-determined
conditions.
The object of this standard is to state:
a) the characteristics of circuit-breakers;
b) the conditions with which circuit-breakers shall comply with reference to:
1) operation and behaviour in normal service;
2) operation and behaviour in case of overload and operation and behaviour in case of
short-circuit, including co-ordination in service (discrimination and back-up protection);
3) dielectric properties;
c) tests intended for confirming that these conditions have been met and the methods to be
adopted for these tests;
d) information to be marked on or given with the apparatus.
