NBSe NBSX1 Series New Design 4P 40A 6kA Breaking Capacity MCB Micro
Circuit Breaker, 3 phase circuit breaker
Tips:
1. MCB is for non-professional 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.
1. Application
The product is mainly used in AC50/60Hz single pole230V or
two,three,four pole 400V voltage for overload and short-circuit
protection as well as for unfrequent on-and-off switching electric
