No the Powerpact H & J frame breakers are thermal magnetic breakers and do not have interchangeable rating plugs.
You can change the trip units in the unit mount breakers (not I-Line mount) if they were order with this capability, however, the 15-60 amp trip units can only be used in the 60 amp frame and the 70 - 150 amp trip units can only be used in the 150 amp frame.
