Description

Built to maintain older electrical systems, the NC025 is a single-pole miniature circuit breaker designed for legacy Federal Pacific enclosures. It features the signature Stab-Lok mounting style, ensuring a precise fit into existing panelboards without the need for adapters. The ultra-thin half-inch wafer profile maximizes available space while delivering 25A of thermal-magnetic protection. Rated for 10kAIC at 120VAC, this component is fully cross-referenced to be replaced by the UBIF025N.

Product FAQs

7 answers
Which load centers are compatible with the Federal Pacific NC025?

The NC025 is designed exclusively for use in legacy Federal Pacific Electric (FPE) Stab-Lok load centers. It features the proprietary Stab-Lok plug-on mounting design and will not fit in standard panels from other manufacturers.

Is there a modern replacement available for the FPE NC025?

Yes, Connecticut Electric manufactures the UBIF025N, which serves as a direct, newly manufactured replacement for the legacy Federal Pacific NC025. It fits the same Stab-Lok enclosures and provides identical 25-amp, single-pole protection.

What is the physical footprint of the NC025 breaker?

The NC series breakers, including the NC025, feature a half-inch thin profile. This ultra-thin wafer design allows them to maximize space within the panelboard compared to standard one-inch thick NA series breakers.

Can I use an NC025 in place of an NA series breaker?

The NC025 is a half-inch thin breaker, whereas the NA series breakers are one-inch thick. While both use the Stab-Lok mounting design, replacing an NA breaker with an NC breaker requires verifying that the specific panel busbar configuration accepts thin breakers in that slot.

What wire sizes are accepted by the lugs on the NC025?

The terminal lugs on this breaker accept copper or aluminum conductors ranging from 14 AWG to 6 AWG. Always ensure proper torque specifications are met during installation to prevent loose connections.

How does the trip mechanism function on the NC025?

The NC025 utilizes a fixed thermal-magnetic trip unit. The thermal component provides long-time protection against sustained overloads, while the magnetic component delivers instantaneous protection against short circuits.

Are there safety concerns associated with legacy Federal Pacific Stab-Lok panels?

Yes. Legacy FPE Stab-Lok panels and breakers have a documented history of failing to trip during overcurrent conditions and experiencing loose busbar connections. Many home inspectors and licensed electricians recommend upgrading the entire panel rather than replacing individual breakers.

    Purchased four circuit breakers

    Was happy with all the service would’ve wished the person would inform me if I would’ve spent $15 more I could’ve got free shipping. That way I could’ve ordered another 20 amp circuit breaker. And got it for free.

    Federal Pacific breakers

    I wasn't sure about ordering my particular breakers online because they don't make replica replacements but found the warranty outstanding. The follow-up call as a new customer and the speed with which my order was processed and completed was superior. The price was 1/3 what the ONE local supplier charged.
