FPV-125-4P 1000V DC MCB PV Mini Circuit Breaker

FUNCTIONS: Used to protect power distribution facilities from overload and short-circuit damage, and can also be used for control and isolation. APPLICATION:1.DC power supply:Such as communication power supply, EPS, UPS, etc. in the information industry;2.Rail transit and electric locomotive;3.Ship power system and electrical propulsion system Excellent current limiting performance, which can accurately protect relay protection and automatic devices from overload, short circuit and other fault hazards Special arc extinguishing and current limiting system, which can quickly break the fault current of the DC distribution system, greatly improving the differential coordination ARC EXTINGUISHING: DC arc extinguishing is harder than AC; DC mini circuit breaker has magnetic system for assistance.
