Federal Pacific Electric NEF421020 2 Pole Circuit Breaker

Federal Pacific Electric NEF421020 is a 2 pole circuit breaker rated for 20 amps at 480 volts. Identified by the NEF421020 part number, this Federal Pacific Electric (FPE) device is designed to interrupt current to protect electrical circuits from overloads and short circuits by disconnecting power when the current exceeds its rating. In a two-pole configuration, it provides simultaneous interruption of both conductors in a circuit, offering dual-line protection for the protected circuit. The 20 amp, 480 volt specification defines the electrical capacity and operating range of this unit, helping technicians confirm it matches the needs of higher-voltage, two-pole protection applications. By interrupting current during fault conditions, it helps protect conductors, devices, and circuits from damage and reduces the risk of fire due to overcurrent. The part number NEF421020 uniquely identifies this unit for ordering or cross-reference in compatible Federal Pacific Electric installations.
