Product FAQs
4 answersWhat panels are compatible with the NA3P90 breaker?
This plug-on breaker is designed exclusively for use in legacy Federal Pacific Stab-Lok three-phase load centers. It will not fit in standard load centers from other manufacturers.
How much panel space does the NA3P90 require?
As part of the NA series of thick Stab-Lok breakers, it requires three inches of panel space, taking up one inch per pole.
Is there a modern replacement for the obsolete NA3P90?
Yes, Connecticut Electric manufactures the UBIF390N, which is an ETL-listed, modern replacement designed to fit the same Federal Pacific Stab-Lok panels.
Are there safety concerns when installing legacy FPE Stab-Lok breakers?
Yes. Legacy Federal Pacific Stab-Lok panels and breakers have a well-documented history of failing to trip during overcurrent conditions. Many licensed electricians and inspectors strongly recommend replacing the entire panel to ensure building safety.
