MicroVersaTrip Plus or PM trip unit self-tests and
functional trip/no-trip tests. It also provides for defeat of
the ground-fault function and can be used in conjunction
with high-current test equipment. Interface is via a plug
on the front of the trip unit and tests can be conducted
with the breaker in service. The kit can also be powered
by a 120 Vac source.
