It features a full-size one-inch-per-pole footprint and common trip functionality for three-phase applications. Rated at 10kAIC at 240VAC, it handles standard commercial loads without requiring aftermarket adapters. For modern alternatives, the UBIF0330N serves as a recognized substitute.Specifications

Product FAQs
6 answersWhat panels accept the NA3P30 circuit breaker?
The NA3P30 is designed exclusively for Federal Pacific Electric (FPE) Stab-Lok load centers and panelboards. It features a proprietary plug-on design that is not compatible with standard load centers from other manufacturers.
What is the modern replacement for the obsolete FPE NA3P30?
The Connecticut Electric UBIF330N serves as an exact, modern cross-reference for the NA3P30. It provides the same 30-amp, 3-pole configuration and fits directly into Stab-Lok panels.
How does the NA series differ from the NB series for installation?
The NA series, including the NA3P30, features a plug-on mounting style that snaps directly onto the panel busbar. The NB series is the bolt-on equivalent designed for commercial Stab-Lok panels that require bolted connections.
How much panel space does the NA3P30 require?
This is a full-size Stab-Lok breaker that measures 3 inches wide. It requires three standard 1-inch spaces on the panel busbar for installation.
Why do inspectors often flag Federal Pacific Stab-Lok breakers?
Original FPE Stab-Lok breakers have a documented history of high defect rates, often failing to trip during overcurrent or short-circuit conditions. Electricians frequently recommend evaluating or replacing older Stab-Lok panels to mitigate fire risks and ensure system safety.
Are there other brand names that manufactured the NA3P30?
Yes. Due to corporate changes and licensing, identical Stab-Lok breakers were also manufactured and branded under names like Federal Pioneer, American Circuit Breaker, and Challenger.
