UEW5 SERIES INTELLIGENT AIR CIRCUIT BREAKER UEW5 Series intelligent Air Circuit Breaker(ACB) is applicable for the power distribution circuit under the condition of AC50HZ, rated working voltage 400V

1 UEW5 SERIES INTELLIGENT AIR CIRCUIT BREAKER UEW5 Series intelligent Air Circuit Breaker(ACB) is applicable for the power distribution circuit under the condition of AC50HZ, rated working voltage 400V or 690V, and rated current 200A-6300A. The circuit breakers with high braking capacity and Zero Flashover, take the role of distributing power and protecting wires and equipment from being damaged by overload, under-voltage, short circuit and ground fault etc. The circuit breakers provide intelligent protection function and precise selective protection which will improve reliability and safety of power supply to avoid unnecessary power failure. Relative Standard: IEC low-voltage switchgear and control gear part 2:circuit breaker GB low-voltage switchgear and control gear part 2:circuit breaker Operating Temperature Range:Common type:-5 ~40 Low temperature type: -40 ~55 Storage Temperature Range:-40 ~70
