GENERAL INFORMATION
The Mpro Trip Unit is an electronic device that interfaces with a
circuit breaker. It monitorsthe breaker phase currents, neutral
current and/or voltage and trips the breaker in the event of an
over-current or voltage related condiƟon.
It also can provide protecƟve relay funcƟons, advanced metering,
diagnosƟc features, and communicaƟons. The Trip Unit can be
removed or replaced in the Įeld by de-energizing and removing the
cover of the circuit breaker.
The Trip Unit also connects with the circuit breaker Ňux shiŌer to
provide the electromechanical tripping funcƟon.
A user interface is provided on the front panel to allow adjustment of
the Trip Unit’s parameters.
