NDD1

The NDD1 Series Motor Protection Circuit Breaker (hereinafter referred to as the breaker) is suitable for AC 50/60Hz circuits with a rated voltage up to 690V and a rated current up to 80A. It provides overload, short-circuit, phase failure, and phase unbalance protection for three-phase squirrel-cage asynchronous motors, as well as infrequent starting control. It can be used for distribution line protection and infrequent load switching, and can also serve as an isolator. The breaker can be used in conjunction with alarm contacts, auxiliary contacts, shunt releases, and undervoltage release accessories.
