Issue:
Can the trip unit on a PowerPacT R frame breaker be upgraded in the field?

Product Line:
Powerpact Circuit Breakers

Resolution:
Only if it is a Micrologic trip unit. Breakers with the ET1.0I cannot be upgraded or replaced.

Note for RJ and RL only:  New trip units can only go on breakers with date codes 09011 (first day of 2009) or higher. For breakers prior to 09011, must use older trip units with date codes prior to 09011. Older trip units with date codes prior to 09011 are not sold. If one cannot be located, then the breaker would also have to be replaced to upgrade the trip unit.
