Product FAQs
4 answersWhat equipment is the NEJ223175 designed to fit?
This N-frame breaker is engineered for direct installation into legacy Federal Pacific panelboards that require bolt-on NEJ series molded case circuit breakers.
Is the NEJ223175 a direct replacement for older N-frame breakers?
Yes, this unit serves as an exact replacement for obsolete Federal Pacific N-frame 175A, 2-pole breakers, allowing you to maintain existing infrastructure without requiring adapter kits.
Are the trip settings on the NEJ223175 adjustable?
No. It features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) trip functions, meaning the trip curve cannot be field-adjusted.
What are the acceptable wire sizes for the terminals on this breaker?
The factory-installed load lugs accommodate wire gauges from 4 AWG up to 300 kcmil. Verify that your conductor size aligns with the panelboard bending space requirements before installation.
