Description
High-amperage commercial applications relying on vintage infrastructure can depend on the Federal Pacific NJJ232600 for robust overcurrent safety. This 600A, 3-pole molded case circuit breaker is purpose-built to mount into legacy FPE distribution panels and switchboards, bypassing the complexity of modernizing entire enclosures. Delivering 22kAIC at 240VAC, it features a non-interchangeable thermal-magnetic trip unit. It is an ideal replacement option, cross-referencing with the NJL631600.Specifications

Product FAQs
6 answersWhat types of enclosures or panels are compatible with the NJJ232600?
This breaker is designed specifically for legacy Federal Pacific Electric (FPE) distribution panels and switchboards that accept N-Frame bolt-on circuit breakers.
What are the wire size requirements for the terminal lugs on this breaker?
The included lugs are designed to accept two conductors per phase, accommodating wire sizes from 3/0 AWG up to 500 kcmil.
How is this FPE 600A breaker secured within the panel?
It utilizes a bolt-on mounting style, meaning the breaker must be mechanically bolted directly to the busbars of a compatible FPE switchboard or distribution panel to ensure a secure electrical connection.
What type of trip unit is equipped on the NJJ232600?
It features a fixed thermal magnetic trip unit that provides Long-Time and Instantaneous (LI) protection functions for standard commercial overcurrent and short-circuit defense.
Is the Federal Pacific NJJ232600 still in active production?
No, Federal Pacific Electric is no longer in business. This unit is sourced as a legacy replacement component to maintain existing FPE commercial and industrial electrical systems.
Can the NJJ232600 be installed in a standard residential Stab-Lok load center?
No. This is a large 600-amp N-Frame molded case circuit breaker intended strictly for commercial and industrial distribution panels, and it will not fit or operate in residential Stab-Lok panels.
