Sentron Molded Case Circuit Breakers - Motor Circuit Protectors
Siemens instantaneous trip motor circuit protectors are recommended for use in combination motor starters to provide selective short-circuit protection for the motor branch circuit. The adjustable instantaneous trip feature of the Siemens motor circuit protector provides for a trip setting slightly above the peak motor in-rush current. This circuit breaker has no time-delay trip element. Therefore it must be used in conjunction with-and immediately ahead of-the motor-running over current protection device. Each Sentron motor circuit protector accepts the same terminals and accessories as the equivalent Sentron circuit breakers.
