_____________

1 Scope
Replace the entire existing text by the following:
This International Standard is applicable to mechanical switching devices designed as "circuit-
breakers for equipment" (CBE) for household and similar applications. CBEs according to this
standard are intended to provide protection to circuits within electrical equipment including its
components (e.g. motors, transformers, internal wiring). This standard covers also CBEs
applicable for protection of electrical equipment in case of undervoltage and/or overvoltage.
This standard also covers CBEs which are suitable for isolation.
NOTE The term "equipment" includes appliances.
CBEs are not applicable for overcurrent protection of wiring installations of buildings.
CBEs according to this standard have:
– a rated voltage not exceeding 440 V a.c. (between phases) and/or d.c. not exceeding
250 V;
– a rated current not exceeding 125 A;
– a short-circuit capacity (I ) of at least 6xI (a.c types) and 4xI (d.c.-types) but not
cn n n
exceeding 3 000 A.

60934 Amend. 2 © IEC:2013 – 3 –
CBEs may have a conditional short-circuit current rating in association with a specified short-
circuit protective device (SCPD). A guide for coordination of a CBE associated in the same
circuit with a SCPD is given in Annex F.
For CBEs having a degree of protection higher than IP20 according to IEC 60529, for use in
locations where hazardous environmental conditions prevail (e.g. excessive humidity, heat or
cold or deposition of dust) and in hazardous locations (e.g. where explosions are liable to
occur), special constructions may be required.
This standard contains all the requirements necessary to ensure compliance with the
operational characteristics required for these devices by type tests. It also contains the details
relative to test requirements and methods of testing necessary to ensure reproducibility of test
results.
This standard states:
a) the characteristics of CBEs;
b) the conditions with which CBEs shall comply, with reference to:
1) their operation and behaviour in normal service;
2) their operation and behaviour in case of overload;
3) their operation and behaviour in case of short-circuits up to their rated short-circuit
capacity;
4) their dielectric properties;
c) the tests intended for confirming that these conditions have been met and the methods to
be adopted for the tests;
d) the data to be marked on the devices;
e) the test sequences to be carried out and the number of samples to be submitted for
certification purposes (see Annex C);
f) the routine tests to be carried out to reveal unacceptable variations in material or
manufacture, likely to affect safety (see Annex J).
3 Terms and definitions
