NBSM1-125 Series Mini Circuit Breaker , din mount circuit breaker


A residual-current device (RCD), or residual-current circuit breaker (RCCB) is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor. Such an imbalance may indicate current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions. RCCBs are designed to disconnect quickly enough to prevent injury caused by such shocks. They are not intended to provide protection against overcurrent (overload) or all short-circuit conditions.


1. Application

DN DK mcb 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 equipment and lighting circuit under nrmal conditionl

the product is suitable for industry,business,building,ressidence,etc.

It's conformity with CE GB10963,IEC60898 EN898 standards.
