Product FAQs
5 answersWhat load centers are compatible with the NA3P25 circuit breaker?
This breaker is designed exclusively for Federal Pacific Stab-Lok load centers and panelboards. It features a proprietary plug-on design that will not fit in standard load centers from other manufacturers.
What is the modern cross-reference for the obsolete NA3P25?
The Connecticut Electric UBIF325N serves as a direct aftermarket replacement for the NA3P25, providing the exact same form factor and electrical ratings for Stab-Lok panels.
Are there known safety issues with Federal Pacific Stab-Lok breakers?
Yes, legacy Federal Pacific Electric (FPE) Stab-Lok panels have documented safety concerns, primarily involving breakers failing to trip during overcurrent events. Industry professionals often recommend a complete panel upgrade, though replacement breakers can restore temporary functionality.
How much panel space is required to install the NA3P25?
This three-pole breaker features a full-size body design, requiring three standard one-inch spaces on the Stab-Lok busbar.
Does the NA3P25 require any special mounting hardware?
No, it uses the standard Stab-Lok plug-on connection. It presses directly into the panel busbar without the need for bolting or additional adapter kits.
