Description
Commercial facilities utilizing older Federal Pacific infrastructure can rely on this 35-amp, three-pole unit for continued operation. It features the proprietary Stab-Lok mounting system, allowing it to snap into original load centers without modification. The breaker includes a color-coded handle for quick visual identification and delivers a 10kAIC rating at 240VAC. When original stock is unavailable, the UBIF335N serves as an exact functional substitute.Specifications

Product FAQs
6 answersWhat load centers are compatible with the NA3P35 circuit breaker?
This breaker is designed exclusively for use in Federal Pacific Stab-Lok 3-phase load centers. It features the proprietary Stab-Lok plug-on mounting system and will not fit panels from other manufacturers.
Can the NA3P35 be used in a single-phase panel?
No. As a 3-pole breaker, the NA3P35 is designed specifically for 3-phase Federal Pacific Stab-Lok load centers. It requires three spaces on the busbar and will not operate correctly in a single-phase system.
Is there a modern replacement available for the Federal Pacific NA3P35?
Yes. If original Federal Pacific stock is unavailable, the Connecticut Electric UBIF335N serves as an exact functional substitute for this 3-pole, 35-amp breaker.
Are there safety concerns associated with legacy Federal Pacific Stab-Lok breakers?
Yes. Legacy FPE Stab-Lok panels and breakers have a documented history of failing to trip under overload or short-circuit conditions. Licensed electricians often recommend replacing the entire panel. If a replacement breaker is required to maintain an existing system, use a modern certified substitute like the UBIF335N or ensure the replacement is properly tested.
What wire sizes are accepted by the lugs on the NA3P35?
The load side lug terminals on this breaker accommodate wire sizes ranging from 14 AWG up to 2 AWG.
How does the trip mechanism function on the NA3P35?
It utilizes a fixed thermal-magnetic trip mechanism. The thermal component provides long-time protection against sustained overloads, while the magnetic component offers instantaneous protection against short circuits.
