Item Name: GTW2 series Air Circuit Breaker
GTW2 series intelligent air circuit breakers (hereinafter referred to as ACB), are applied to rated voltage 400V, 50Hz, rated current 630A~4000A, They are designed for power distribution in distribution network end for protection of electric circuit and power equipment against over load, under voltage, short-circuit and single phase earthed fault, The intelligent trip unit designed specially for the ACBs can be ised for discrimination protection in order to avoid unnecessary down time, and can also be available for increasing the reliability of power supply.
Standard: IEC 60947-2
