NLDB1L-63 series residual current circuit breaker is suitable for AC 50Hz (or 60Hz) lines with rated voltage 400V(230V for single phase) and rated current from 3A to 63A. It has protective functions such as leakage and electric shock, overload, and short circuit. According to user requirements, overvoltage protection can be added to ensure personal safety and prevent equipment accidents caused by leakage current. It can also be used to protect lines from overload and short circuit. Under normal circumstances, it can used as infrequent circuit breaker for breaking and switching, and leakage circuit breaker with rated residual operating current of 30mA can provide direct protection against personal electric shock.

This product complies with the standards: GB/T16917.1, GB/T16917.22, IEC61009-1, IEC61009-2-2.
