Std1-63 Miniature Circuit Breaker 2p 250VDC MCB

Product Description

Product Description

GENERAL

STD1-63 ;STD11-125 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 excellent performance,and avoid the occurrence of the fault. The products can protects the solar photovoltaic power

generation in the important devices in PV module from high DC reverse current and due to failure of the inveter AC feedback current hazards,to enture the reliable operation of solar photovoltaic power generation system. It is used on bulidnings and similar places the line facilities of over current protection,can also be used in less frequent break operation.And has small volume,breaking capacity, arcing distance is short,fast closing and installation is convenient .
