Description
Maintaining older electrical infrastructure demands precise hardware matching. This 90-amp, two-pole device delivers essential long-time and instantaneous trip functions for legacy 120/240VAC applications. Built to integrate with classic Federal Pacific Stab-Lok load centers, the unit installs into the original busbar configuration. It effectively replaces aging equipment and serves as an alternative to the UBIF0290N model. The long-body construction includes a color-coded handle for quick ID.Specifications

Product FAQs
4 answersWhat is the difference between Federal Pacific NA and NC series breakers?
The NA series features a full-size design measuring 1 inch per pole, making a 2-pole breaker 2 inches wide overall. The NC series is a thin or half-size design measuring 1/2 inch per pole. The NA2P90 is a full-size NA frame breaker and requires two full 1-inch spaces in a Stab-Lok panel.
Are there known safety concerns with Federal Pacific Stab-Lok panels?
Yes. Legacy Federal Pacific Electric (FPE) Stab-Lok panels have a documented history of breakers failing to trip during overcurrent or short-circuit conditions. Many home inspectors and licensed electricians recommend evaluating or completely replacing legacy FPE panels with modern, code-compliant load centers to mitigate fire risks.
How does the NA2P90 connect to the panel busbar?
The NA2P90 uses a proprietary plug-on Stab-Lok connection specific to Federal Pacific load centers. It pushes directly onto the panel busbar without the need for mounting bolts.
Are there modern UL-classified replacements for legacy Federal Pacific breakers?
Yes. Connecticut Electric manufactures new, UL-classified replacement breakers under the UBI brand that are specifically designed to fit legacy Federal Pacific Stab-Lok load centers.
