Description

A seamless replacement for aging infrastructure, the Federal Pacific NAGF25 delivers 25 amps of ground-fault protection. It secures 120VAC branch circuits against leakage currents. This plug-on breaker installs into classic Federal Pacific Stab-Lok enclosures. It provides a perfect fit for older panels and acts as a verified cross-reference for the UBIF225N. The device utilizes thermal-magnetic trip mechanisms alongside a 5mA Class A GFCI threshold and includes a pigtail neutral wire.

Product FAQs

5 answers
Will the NAGF25 fit standard modern load centers?

No. This breaker features a specific plug-on configuration designed exclusively for legacy Federal Pacific (FPE) Stab-Lok load centers and will not fit modern panels from other manufacturers.

How is the neutral connection handled during installation?

The breaker includes a factory-installed pigtail neutral wire. This wire must be routed and secured to the neutral bus bar in the Stab-Lok panel to enable the ground fault detection circuitry.

What level of ground fault protection does this breaker offer?

It provides Class A ground fault protection, meaning the internal circuitry is calibrated to trip and interrupt power when a leakage current of 5mA or greater is detected.

Does this breaker provide standard overcurrent protection in addition to GFCI?

Yes. It utilizes a thermal-magnetic trip mechanism to protect against standard overloads and short circuits, alongside the dedicated ground fault protection.

Can I use a Connecticut Electric breaker in place of the NAGF25?

Yes. Connecticut Electric manufactures new, safety-agency-listed UBI series replacement breakers specifically designed to fit FPE Stab-Lok panels, serving as a direct cross-reference for original NAGF models.

    Just what we ordered

    The circuit breaker arrived in a timely manner (delayed a day due to weather). The website was easy to maneuver. The refurbished breaker works great!
