Detailed
APPLICATION:
DZ20 series molded case circuit breaker (hereinafter referred to as circuit breaker) is suitable for distributing line of AC50Hz, rated working voltage 380V(400V)and below, rated current 16A~1250A, used to distribute electric energy and protect circuitry and equipment against overload, short-circuit and under-voltage. Hereinto, type Y, J and G circuit breakers of rated current 225A and below and type Y circuit breakers of rated current 400A also can be used to protect motor. Under normal condition, they also can be applied to switch circuitry and start the motor infrequently and respectively. MAIN TECHNICAL
