Product FAQs
5 answersWhich panelboards are compatible with the NJL632300 circuit breaker?
This bolt-on breaker is designed specifically for use in legacy Federal Pacific NJL series panelboards and switchboards.
What are the acceptable wire sizes for the lugs on the NJL632300?
The standard factory lugs accept aluminum or copper conductors ranging from 250 kcmil to 500 kcmil. Ensure proper torque specifications are followed during installation.
How does the fixed thermal magnetic trip unit operate on this N-Frame breaker?
The LI (Long-Time, Instantaneous) trip unit provides non-adjustable thermal protection against sustained overloads and fixed magnetic protection for immediate short-circuit clearing.
Is the Federal Pacific NJL632300 still in active production?
Federal Pacific is a legacy brand and no longer manufactures new molded case circuit breakers. When replacing an NJL frame, facilities must either source exact legacy replacements or consult an engineer for a modern retrofit kit.
Does the NJL632300 share the same design as Federal Pacific Stab-Lok breakers?
No. The NJL632300 is a heavy-duty industrial molded case circuit breaker with a bolt-on connection. It is completely different from the residential Stab-Lok plug-on design.
