Factory Smart Intelligent AC Circuit Breaker Wsb5 (L) -40 MCB ODM OEM
WSB5-40/WSB5 (L) -40 series MCB is one of updated type MCCBs researched and developed by the company by using advanced design and manufacture technology internationally.
WSB5-40 series “phae line + neutral line” circuit breaker is applied in single residential line of AC 50Hz or 60Hz, rated voltage 230V to make overload and short circuit protection to the electrical line. The product is big in breaking capacity and small in volume with width 18mm. It is null line and live line breakd at same time which put personal harm and risk an end that may caused by reverse connecting of null line or potential of null line earthing. It is the optimal distribution protecting switch for resisdual houses at present, meets standards IEC 60898 and GB 10963.1
WSB5L-40 sereis (phase + neutral + earth leakage) circuit breaker is applied in single phase residential line of AC 50Hz or 60Hz, rated voltage 230V for earth leakage protection, as well as protection of overload and short circuit for civil electrical line. The product is small in volume, big in breaking capacity. It can still make earth leakage protection even null and live lines cut meanwhile, and live line connects reversely. It meets standards IEC 61009 and GB 16917.1
