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.
