Product FAQs
6 answersWhich panelboards accept the Federal Pacific NE224050 circuit breaker?
The NE224050 is a bolt-on molded case circuit breaker designed specifically for legacy Federal Pacific NE series commercial panelboards. It will not fit standard residential load centers.
What wire gauge range is supported by the NE224050 terminals?
The integrated lugs on this 50A breaker accommodate conductors ranging from 14 AWG to 2 AWG.
What is a direct replacement or cross-reference for the NE224050?
The UBINE224050 is a direct aftermarket substitute for the original Federal Pacific NE224050, matching the physical dimensions, bolt-on mounting, and electrical specifications required for NE panelboards.
Is the NE224050 part of the Federal Pacific Stab-Lok series?
No. The NE224050 is an NE frame commercial bolt-on breaker. It is completely different from the plug-on Stab-Lok breakers commonly found in older residential FPE load centers and cannot be used as a replacement for them.
What trip functions are included in the NE224050 thermal-magnetic breaker?
This breaker features fixed long-time and instantaneous (LI) trip functions. The thermal component provides delayed protection against sustained overloads, while the magnetic component trips instantly during severe short circuits up to 18kAIC at 240VAC.
How is the NE224050 secured inside the panelboard?
This breaker utilizes a bolt-on connection. It must be mechanically fastened to the busbar of a compatible Federal Pacific NE panelboard using screws, ensuring a secure and reliable contact for commercial applications.
