Can the Powerpact M circuit breaker with ET1.0 trip unit be secondary injection tested?
Issue: Powerpact M with ET1.0 trip unit secondary injection compatibility
Product Line: Circuit Breakers
Environment: Powerpact M with ET1.0 trip unit
Resolution:
The old style ET1.0 trip unit with a single blue Ii adjustment dial is compatible with the hand held test kit (HHTK) and full function test kit (FFTK) but not compatible with the Service Interface and EPC software automatic trip curve test. NOTE: Older ET1.0 trip units have the test port covered. Cut the label to access the trip unit port.
The new style ET1.0 trip unit with white dials (breaker catalog number has the E10 suffix) is not compatible with the HHTK, FFTK or the service interface EPC software.
