DC circuit breaker, 2-pole, 40A, 1000V DC
Features:The DC mini circuit breaker is designed for use in photovoltaic power generation and distribution systems, such as small-circuit photovoltaic combiner box, DC controller and other electrical equipment.The rated voltage of the DC circuit breaker can reach 1000V, and the rated operating current is 40A.It has a scientific arc extinguishing and current limiting system,which can quickly disconnect the fault current at the DC side of the photovoltaic system, and realize reverse current protection, providing sufficient guarantee for the safe operation of the DC side of the photovoltaic system.Used for isolation, short circuit and overload protection.Modular design. Convenient mounting on a DIN rail.Complies with IEC/EN 60947-2 standards and environmental protection requirements.
