Federal Pacific Electric NEF-SWD 1-Pole Circuit Breaker is a 20 A unit designed to protect a single branch circuit inside electrical panels. It carries ratings for 277 VAC and 125 VDC, enabling use in circuits that require protection at either voltage level. This NEF-SWD type breaker provides overcurrent protection in commercial or industrial power-distribution systems where a compact, single-pole device is needed for a 20-amp circuit.
