Note
1 MCB is for non-professional operation by those untrained, and no
maintenance is required
2Satisfying conditions and applications as mentioned above,MCB with
ON-OFF indicating device is considered suitable for isolation
function.
3Particular devices such as surge protective devices,surge arrester
etc are recommended to install at upstream line to MCB as
precaution against potential surge voltage and current occurring at
its power input side.
4 Appropriate tripping curve being chosen and properly installed,
MCB trips and switches off its protected circuit in case of fault,
and thus provides protection against electric shock.
