Can the trip unit be replaced on electronic trip breaker with a Micrologic Series B trip unit?

Issue:
Series B Micrologic trip unit on older breaker needs to be replaced.

Product Line:
Legacy Series Electronic Trip breakers with Series B Micrologic trip units.

Resolution:
Series B Micrologic trip units installed in the legacy L, M, N, and P breakers are not replaceable. Only Series B trip units installed in SEF/D breakers can be replaced. Series B trip units CANNOT be installed to replace older trip unit series in SEF/D breakers. All of these breakers are now obsolete and need to be replaced with PowerPact or MasterPact electronic trip breakers.
