American NEF437030 Three Pole Circuit Breaker

Federal Pacific Electric (FPE) NEF437030 is a three-pole molded-case circuit breaker in the NEF series, designed for industrial power distribution. This bolt-on device carries a 30 A rating and is intended for 480 VAC three-phase circuits, enabling protection for feeders and motors in commercial and industrial panels. The unit's interrupting capacity is 14 kAIC at 480 VAC, providing short-circuit protection for typical industrial loads. As a bolt-on MCCB, it is installed on compatible bus assemblies using standard mounting hardware, with three poles ensuring simultaneous protection of all three phases. Although sold under the Federal Pacific Electric (FPE) umbrella, distributors often list the NEF437030 as part of the American/FPE catalog family due to branding variations in the market. The NEF series is widely used in industrial environments requiring bolt-on, three-pole protection for 480 VAC systems, including applications such as conveyor motors, pumps, and HVAC equipment.
