Product FAQs
6 answersWhich panelboards are compatible with the NEJH223225 circuit breaker?
This breaker is designed for installation in legacy Federal Pacific NDP panelboards. It requires a bolt-on connection and fits into the N-Frame spaces within these specific distribution panels.
Is there a direct aftermarket replacement for the Federal Pacific NEJH223225?
Yes, the Connecticut Electric UBI series offers a direct cross-reference under part number UBINEJH223225. This aftermarket option is designed to fit the same Federal Pacific NDP panelboards without requiring modification kits.
What mounting hardware is required to install this breaker in an NDP panelboard?
To mount NEJ, NEJH, or HEJ frame breakers into a Federal Pacific NDP panelboard, you typically need the NDPNEJ twin mounting strap kit. This hardware secures the bolt-on connections to the panel bus.
Does the NEJH223225 feature adjustable trip settings?
No, this breaker utilizes a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous protection but does not allow for field adjustments of the trip curve.
What wire sizes are accepted by the lugs on the NEJH223225?
The factory lugs accept aluminum or copper conductors ranging from 4 AWG up to 300 kcmil. Ensure proper torque specifications are followed during installation to maintain a secure connection.
Are there any safety concerns with legacy Federal Pacific equipment?
While this commercial N-Frame breaker is distinct from the residential Stab-Lok series, many facilities choose to upgrade aging Federal Pacific distribution equipment due to the obsolescence of original parts. Always have a licensed electrician inspect legacy panelboards for signs of busbar wear or thermal damage before installing replacement breakers.
