What is the culture of CGZ 63 amp circuit breaker ?

Product Description

Special Tips

1.63 amp circuit breaker is for nonprofessional operation by those untrained, and no maintenance is required

2. Satisfying conditions and applications as mentioned above,MCB with “ON-OFF” indicating device is considered suitable for isolation function.

3. Particular 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.

5. B,C,D tripping curve(see graphics 1):
