Built to support 240V residential and commercial circuits, the NA215 provides 15 amps of two-pole thermal-magnetic protection. The two-inch wide design features a color-coded handle and an internal common trip mechanism to disconnect both legs simultaneously during an overcurrent event. This legacy component mounts into original Federal Pacific Stab-Lok panelboards. It serves as an exact fit for older installations and can be replaced by the UBIF215N when upgrading.

Product FAQs
4 answers
What is the exact panel footprint of the NA215 breaker?
The NA series designates a standard thick-style Federal Pacific circuit breaker body. Measuring 1 inch per pole, this 2-pole breaker requires exactly 2 inches of horizontal space on a Stab-Lok busbar.
What is the modern cross-reference for the NA215?
The Connecticut Electric UBIF215N is a direct, newly manufactured replacement for the legacy Federal Pacific NA215. It shares the same 2-inch thick body and Stab-Lok mounting design.
Are there specific inspection steps when installing replacement Stab-Lok breakers?
Yes. Legacy Federal Pacific Stab-Lok load centers are known for busbar connection issues. Before installing a replacement breaker, licensed electricians must carefully inspect the panel busbar prongs for pitting, arcing, or thermal damage.
How does the Stab-Lok connection differ from standard plug-on breakers?
Instead of gripping a central bus rail, Stab-Lok breakers like the NA215 use slots on the back of the breaker casing to plug directly onto specialized prongs protruding from the panel busbar.
