CNC Electric Solar DC 250V 500V 750V 1000V 63A 80A MCB 1p 2p 3p 4p Miniature Circuit Breaker

Product Description

General
 

YCB9-80DM DC series circuit breaker is specially used for the photovoltaic system, it's rated working voltage can be up to DC1000V. The circuit breaker adopts a special extinguishing and current limiting system, which can quickly switch off the fault current of the DC distribution system, to protect
photovoltaic module, the important component in solar power generation system from the harm of high DC reverse current and AC feedback current caused by inverter failure, and ensure the reliable operation of solar photovoltaic power generation system.

Standard: IEC/EN 60947-2
