Product Description

The Federal Pacific NA50 is a 50 Amp, 1-pole, 120VAC Type NA Stab-Lok circuit breaker designed for use in compatible Federal Pacific Electric (FPE) electrical panels and load centers.

The NA50 features the original full-size 1-inch Type NA design with a plug-in Stab-Lok connection. It provides thermal-magnetic overload and short-circuit protection with a 10,000 AIC interrupting rating at 120VAC.

This breaker accepts #14 through #2 AWG copper or aluminum conductors and provides long-time and instantaneous trip functions. The NA50 is a discontinued legacy breaker commonly used as a replacement for an existing NA50 in a compatible Federal Pacific Stab-Lok panel.

Important Compatibility Information

The NA50 is a full-size 1-inch Type NA Stab-Lok breaker. It should not be confused with the NC050, which is the thinner 1/2-inch Type NC Stab-Lok breaker.

Before ordering, verify the Federal Pacific manufacturer, NA50 part number, Type NA configuration, 50A rating, 1-pole configuration, 120VAC rating, 1-inch body size, and Stab-Lok connection against your existing breaker and panel.

Do not select a replacement breaker based on amperage alone.
