Item Name: DW17 series Air Circuit Breaker
The breaker is applicable to the circuit of AC380V, 660V and 50Hz as the distribution of electric energy and unfrequent conersion of line. May be applied to protect the overload, under-voltage and short-circuit of line and electric equipment. And has the function of hierarchical-seiecting protection, and can protect the motor, engine, commutating device etc from being broken because of overload short-circuit and under-voltage etc.
