Description
Built for residential and commercial applications, the NA220 delivers 20 amps of thermal-magnetic protection. This legacy component maintains older electrical systems without requiring a panel upgrade. It mounts into classic Federal Pacific Stab-Lok load centers, utilizing a standard plug-on design. For modern alternatives, this unit is replaced by the UBIF220N aftermarket breaker. Rated at 10 kAIC at 120/240VAC, it features a full-size 1-inch per pole width and common trip functionality.Specifications

Product FAQs
6 answersWhat load centers are compatible with the Federal Pacific NA220?
The NA220 is designed exclusively for legacy Federal Pacific Electric (FPE) Stab-Lok load centers. It requires two full one-inch spaces on the busbar and will not fit in panels manufactured by other brands.
Can the NA220 replace a Federal Pacific NC220 breaker?
No. The NA220 is a full-size thick breaker that requires one inch of space per pole, totaling two inches of panel space. It cannot be used in slots designed strictly for half-inch thin NC-series breakers like the NC220.
What is the modern aftermarket equivalent for the Federal Pacific NA220?
The Connecticut Electric UBIF220N is a modern, safety-agency-listed replacement designed to function as a direct equivalent for the obsolete NA220 in FPE Stab-Lok panels.
How is the NA220 installed into a Stab-Lok panel?
The NA220 features a plug-on mounting design that engages directly with the Stab-Lok busbar. Ensure the panel is de-energized before seating the breaker, and verify that the 14 AWG to 2 AWG load wires are properly torqued in the lugs.
Are there known safety issues with legacy Federal Pacific Stab-Lok equipment?
Yes. Original Federal Pacific Stab-Lok breakers have a documented industry history of failing to trip during overcurrent or short-circuit conditions. It is highly recommended to have legacy FPE panels evaluated by a licensed electrician to ensure system safety.
What applications are suitable for this 20A 2-pole breaker?
A 20-amp, 240-volt double-pole breaker is typically installed to protect dedicated 240V circuits, such as electric baseboard heaters, small air conditioners, or 240V shop equipment, provided the continuous load remains within safe operating limits.
