Application

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.

Ambient temperature: -25°C~+40°C, the average during 24 hours should not exceed +35°C; if more than +40°C or less than -25°C,contact with manufacturer;The atmosphere condition; ≤95% Altitude:≤2000m, if exceed 2000m, altitude derating is required;Pollution degree:ll
