Product FAQs
6 answersWhat panels are compatible with the NA3P15 circuit breaker?
The NA3P15 is designed exclusively for use in 3-phase Federal Pacific Stab-Lok electrical panels and load centers. It features a plug-on connection specific to the Stab-Lok busbar design.
Can I use the NA3P15 in a single-phase residential panel?
No. The NA3P15 is a 3-pole breaker intended for 3-phase electrical systems, which are typically found in commercial or industrial settings. Standard residential Stab-Lok panels are single-phase and cannot accommodate a 3-pole breaker.
How much panel space does the NA3P15 require?
The NA3P15 is a standard-width breaker. It requires three full 1-inch spaces, totaling 3 inches of space on the panel busbar.
Does the NA3P15 require a bolt-on connection?
No. The NA3P15 utilizes a plug-on connection. If your Federal Pacific panel requires a bolt-on connection, you will need the NB series equivalent instead.
Are there modern alternatives to the Federal Pacific NA3P15?
Yes. Because original Federal Pacific Electric breakers are obsolete, Connecticut Electric manufactures new, ETL-listed aftermarket replacement breakers under the UBI brand that are designed to fit legacy Stab-Lok panels.
Are there safety concerns with legacy Federal Pacific Stab-Lok breakers?
Yes. Original FPE Stab-Lok panels and breakers have a documented history of failing to trip during overcurrent or short-circuit conditions. Many industry professionals and inspectors recommend replacing the entire panel when possible rather than installing replacement breakers.
