NDD1 Series Motor Protection Circuit Breaker

● Description

The NDD1 series of motor protection circuit breakers (referred to as circuit breakers) apply to be put in the circuit with the AC 50/60Hz, the rated voltage to 690V and the rated current to 80A for the overload, short circuit, open phase and three-phase imbalance protection as well as infrequent starting control of the three-phase cage asynchronous motor, which are also used as isolators for the distribution line protection and infrequent load transfer. The circuit breakers can also be used with alarm contacts, auxiliary contacts, shunt and under-voltage release accessories.

◆ Current setting value adjustable: Adjusted to the indication position of the appropriate current setting value according to the actual working current.

◆ Portable design of accessories: Several auxiliary accessories can be simply and reliably inserted and snapped to be fitted outside the body.

◆ Tripping design of the simulatable mechanism: The mechanism can be tripped via Test to facilitate simulation and testing of the supportive alarm accessories.

◆ Front laser engraving: The engraving mark contents are clear and durable.

NDD1 series of motor protection circuit breaker has obtained China Compulsory Certification (CCC) for products.
