Federal Pacific Electric NB NB220 Circuit Breaker

The Federal Pacific Electric NB NB220 is a two-pole, 20-amp, 240-volt circuit breaker built to protect 240-volt circuits by automatically interrupting current when an overload or short circuit occurs. It is designed for use in electrical panels that accept this specific breaker style, and its 2-pole configuration ensures both hot legs are disconnected simultaneously to prevent uneven voltages on a circuit. The NB220 model designation identifies the device as a 20-amp, 240-volt unit within the NB family, and it is intended for installation where a 240-volt, two-pole protection scheme is required. In practical terms, this breaker protects 240-volt branch circuits in suitable residential, commercial, or industrial electrical distribution setups, providing reliable interruption at the rated current and voltage to help maintain electrical safety and circuit integrity.
