Designed to safeguard commercial networks, this 200A breaker features a robust thermal-magnetic trip mechanism. It manages overloads across single-phase 240VAC applications. The unit mounts into standard Federal Pacific panelboards using a secure bolt-on connection. It functions as a drop-in replacement for obsolete hardware, maintaining compatibility with UBIFPE200N. Built with a non-interchangeable trip unit, it preserves strict factory calibration alongside a 10kA rating.
What panelboards are compatible with the NEJ223200?
This breaker is designed specifically for legacy Federal Pacific (FPE) commercial panelboards configured to accept N-frame or NEJ-series bolt-on breakers.
Will this fit in a standard Federal Pacific Stab-Lok residential load center?
No. The NEJ223200 is a bolt-on molded case circuit breaker for commercial panels. It is not compatible with residential Stab-Lok plug-on load centers.
What size wire can be used with the lugs on this 200A breaker?
The included lugs are designed to accept wire gauges ranging from 4 AWG up to 300 kcmil. Ensure your conductor sizing aligns with local electrical codes for a 200-amp circuit.
How is this breaker secured inside the panelboard?
It features a bolt-on connection type, meaning it must be mechanically bolted directly to the panelboard busbars rather than snapping or plugging into place.
Is the Federal Pacific NEJ223200 still in active production?
No. Federal Pacific Electric is no longer in business, so original NEJ-series breakers are obsolete and typically sourced through legacy inventory.
What is the aftermarket cross-reference for this Federal Pacific breaker?
If an original FPE breaker is unavailable, it is commonly cross-referenced with aftermarket drop-in replacements, such as the Connecticut Electric UBIFPE200N.
Can the trip settings on the NEJ223200 be adjusted?
No. This breaker utilizes a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-calibrated and non-adjustable.
