Federal Pacific Electric NA350 Circuit Breaker

The Federal Pacific Electric NA350 is a three-pole, 50-ampere, 240-volt circuit breaker rated to interrupt up to 10,000 amperes (AIC). This model is designed to fit Federal Pacific Electric panels that accept NA350 breakers and protects three hot conductors in 240V circuits. With its 3P configuration and 50 A rating, it provides branch-circuit protection for installations that rely on NA350‑compatible form factors in FPE panel ecosystems. The 10 kA interrupting capacity specifies the maximum short-circuit current the breaker can safely interrupt at rated voltage, a key specification for controlling fault events in compatible panels. As a dedicated NA350 component, it serves as a replaceable protective device within Federal Pacific Electric distributions for 240V, three-pole protection needs, ensuring proper disconnection behavior when overcurrent occurs.
