Is the interchangeable trip unit in a PowerPacT H or J breaker different than in a H or J with a factory sealed trip unit?

Issue:
What is the difference between a PowerPacT H or J frame breaker with a factory sealed trip unit and an interchangeable trip unit?

Product Line:
Molded Case Breakers

Resolution:
The trip units are the same in either type of breaker. The breakers that have the field interchangeable trip units have line and load markings and they cannot be backfed. They are available as unit mount only and are not available as I-Line. The seal is the real difference. If the seal is broken on a trip unit that is not replaceable the warranty is void.
