Micrologic Trip Units

To be filled

Part of Pact Series

For PowerPact P- and R-frame and Masterpact NW/NT power circuit breakers.

Micrologic Trip Units
  • Features

    PowerPact® P- and R-frame molded case circuit breakers and all Masterpact® power circuit breakers are equipped with the Micrologic® trip system to protect power circuits and loads. Micrologic trip systems use a set of current transformers (called CTs or sensors) to sense the current, a trip unit to evaluate the current m and a tripping solenoid to trip the circuit breaker. Micrologic trip-units are field-interchangeable.
