When Testing GE M-PACT Plus Circuit Breaker, M-PRO Test Box is a Must
Now available for rent from Protec, the GE M-PRO Test Box, is a must have when testing the health and configuration of the GE M-PACT Plus Air Circuit Breaker.
The GE M-PRO Test Box is used as a means of powering up an M-PRO Plus Protection Relay – Electronic Trip Unit, simulating faults by secondary injection or for performing a forced trip of the breaker.
M-PACT Plus breaker will be in the test mode while M-PRO Plus is connected to the Test Box through the test connector.
Connect the Test Box to the M-PRO Plus via the front panel 26-pin connector using a 15-pin to 26-pin converter.
Do not test the M-PRO Plus with the charger still connected, as this will disable power to the M-PRO Plus.
The GE M-PRO Test Box may be used as a simple power box to facilitate viewing of faults (e.g. after a trip) or the
history of trips.
