M611 Motor Protection Circuit Breaker

APPLICATION

The (MPCB) products conform to the standard of JEC 282-1 IEC157-1. VDE0660. IEC947-2. IEC947-4-1. IEC947-5-1. They are used for the circuit of AC voltage-660V. DC voltage-440V, curreut0.1-40A Used for protection of electrical motor's overload and breaker. And also being start of electrical motor. In order to enlarge the range of use, we produce twenty-eight attach-ments for you to choose. For example, vdtage protection, separating unbutton leakage explode protecting, opening door type circuit breaker in adding power, and sealed Fitting case, pan-EL type fitting, track fitting panel, operating key with lock and all kinds of special terminals.
