How can we help you today?

Issue:
Do the Powerpact H and J frame breakers have interchangeable thermal-magnetic trip units?

Product Line:
Molded Case Circuit Breaker

Environment:
Powerpact H- and J- Frame Circuit Breakers

Resolution:
Trip units can be changed on  Powerpact H, J, and L frame breakers with the T or R suffix only. Trip units without the T or R suffix cannot be changed.
Circuit breakers with interchangeable trip units are marked Line and Load and CANNOT be reverse fed.
Note that interchangeable trip units are not possible on I-Line H and J frame breakers or on 2 pole breakers.
