Scope and object

This International Standard is applicable to mechanical switching devices designed as "circuit-breakers for equipment" (CBE) intended to provide protection to circuits within electrical equipment.

NOTE 1 The term "equipment" includes appliances.

NOTE 2 The protected components are usually motors, transformers, internal wiring, etc.

CBEs may have a rated short-circuit capacity higher than that required for overload conditions and may, in addition, have a conditional short-circuit current rating in association with a specified short-circuit protective device (SCPD).

This standard is also applicable to switching devices for protection of electrical equipment in case of undervoltage and/or overvoltage.

It is applicable for a.c. not exceeding 440 V and/or d.c. not exceeding 250 V and a rated current not exceeding 125 A.

This standard covers CBEs which are intended for

- automatic interruption and non-automatic or automatic resetting;

- automatic interruption and non-automatic or automatic resetting and manual switching operation.

It also covers CBE-switches, in which the means for automatic interruption are inhibited or not present by construction (see 3.1.3).

NOTE 3 This standard may be used as a guiding document for voltages up to 630 V a.c.

NOTE 4 Requirements for CBEs suitable for isolation are under consideration.

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.
