Product FAQs
5 answersWhat panelboards accept the Federal Pacific NFJ631200?
This N-Frame molded case circuit breaker is designed specifically for legacy Federal Pacific commercial panelboards and switchboards that require bolt-on NFJ series breakers.
Can the NFJ631200R replace a standard NFJ631200 breaker?
Yes. The NFJ631200R serves as an exact drop-in replacement for the standard NFJ631200. The R designation indicates it includes a factory-installed rotary handle, but it maintains the same physical footprint and bolt-on configuration for legacy enclosures.
How is the NFJ631200 installed into the panel?
This breaker utilizes a standard bolt-on mounting configuration to secure directly to the panelboard bus. The load side features lug terminals that accept conductors from 4 AWG up to 300 kcmil.
Does this breaker share the safety issues associated with Federal Pacific Stab-Lok panels?
No. The NFJ631200 is a commercial-grade, N-Frame molded case circuit breaker with a bolt-on mounting design. It is completely distinct from the residential Stab-Lok plug-on breakers that are known for documented safety and reliability concerns.
Are the trip settings adjustable on the NFJ631200?
No. This breaker is equipped with a non-interchangeable thermal-magnetic trip unit featuring fixed long-time and fixed instantaneous (LI) trip functions.
