GENERAL
WD11-125 Series DC Miniature circuit breaker can quikcly break the fault currents in DC power distribution system, Especially for the DC system of power projects in measurement and protection screen and electric screen between leapfrong tripping accident, the series has excellentperformance, and avoid the occurrence of the fault. The products can protects the solar photovoltaic power generation in the important devicesin PV module from high DC reverse current and due to failure of the inveter AC feedback currenthazards, to enture the reliable operation of solar photovoltaic power generation system. It is used on buildings and similar places the line facilities of over current protection, can also be usedin less frequent break operation. And has small volume, breaking capacity, arcing distance is short, fast closing and installation is convenient.
