VL Motor Circuit Protectors
Siemens instantaneous trip VL 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. Each motor circuit protector has six settings to choose from. With this setting, no delay is introduced in opening the circuit when a fault occurs. 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 type VL motor circuit protector accepts the same terminals and accessories as the equivalent VL circuit breakers.
