This Malaysian 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 overcurrent protection
