General
L7-63Z miniature DC circuit breaker, the special arc, current limiting system, can quickly break the fault currents in DC power distribution system, the differential complexes have been greatly improved. Especially for the DC system of power projects in measurement and protection screen and electric screen between leapfrog tripping accident, .The products can protects the solar photovoltaic power generation system in the important devices in PV module from high DC reverse current and due to failure of the inverter AC feed back current hazards, to ensure the reliable operation of solar photovoltaic power generation system.The circuit breaker has small volume, breaking capacity, arcing distance is short, fast closing and installation is convenient wait for a characteristic. This product applicable to non professionals use and do not need to maintain.
