Product FAQs
3 answersWhat panelboards accept the Federal Pacific NEJ223125 circuit breaker?
The NEJ223125 is a bolt-on molded case circuit breaker designed exclusively for legacy Federal Pacific Electric (FPE) panelboards and switchboards configured for N-Frame or NEJ-Frame devices.
What type of mounting hardware is required for the NEJ223125?
Installing this breaker into legacy FPE distribution equipment requires specific bus connection hardware. Depending on the panelboard type, you may need a strap kit such as the NEJ1K for CDP panels or the NEJ3K for BDP panels.
Are there direct aftermarket replacements for the NEJ223125?
Yes. Because Federal Pacific Electric is defunct, exact replacements are sourced from legacy stock. However, aftermarket manufacturers produce compatible NEJ-frame breakers engineered to fit the same FPE panelboards without requiring adapters.
