Product Description

The Federal Pacific NA240 is a 40 Amp, 2-pole, 120/240VAC Type NA Stab-Lok circuit breaker designed for use in compatible Federal Pacific Electric (FPE) electrical panels and load centers.

The NA240 features the original full-size Type NA design with a 2-inch-wide body and plug-in Stab-Lok connection. Its 2-pole configuration provides common circuit protection for compatible 240V and 120/240V applications.

This breaker provides thermal-magnetic overload and short-circuit protection with long-time and instantaneous trip functions and a 10,000 AIC interrupting rating at 240VAC. It accepts #14 through #2 AWG copper conductors.

The NA240 is a discontinued legacy breaker commonly used as a replacement for an existing Federal Pacific NA240 in compatible Stab-Lok panels.

Product appearance, labeling, and handle style may vary from the images shown.

Important Compatibility Information

The NA240 is a 40A, 2-pole, full-size Type NA Stab-Lok breaker. It should not be confused with thinner Federal Pacific Type NC breakers or with other Stab-Lok breakers that share the same amperage.

Before ordering, verify the Federal Pacific manufacturer, NA240 part number, Type NA configuration, 40A rating, 2-pole configuration, voltage rating, physical size, and Stab-Lok connection against your existing breaker and panel.

Do not select a replacement breaker based on amperage alone.
