Federal Pacific Electric NM631175 Circuit Breaker

The Federal Pacific Electric NM631175 circuit breaker is a three-pole protective device rated for 175 amperes at 480 volts, designed to interrupt fault currents in a 3‑phase power system. Identified by the NM631175 part number, this unit comes from Federal Pacific Electric and is intended for use in electrical panels and distribution panels that handle 3‑phase, 480V service. It carries a 30K rating, indicating its capability to interrupt high fault currents typical in commercial and industrial installations; this makes it suitable for protecting feeders, branch circuits, and equipment connected to a 480V, 3‑phase distribution network. As a 3P breaker, it protects individual circuits within a 480V distribution environment and helps isolate faults to prevent damage to wiring and connected loads. The available details specify the model as NM631175 from FPE, aiding in compatibility checks when replacing or stocking a like‑for‑like unit in systems that require Federal Pacific Electric protection devices.
