Federal Pacific Electric NB232040U Circuit Breaker

The Federal Pacific Electric NB232040U circuit breaker is a 40-amp, 3-pole device rated for 240 volts, designed to interrupt current and protect electrical circuits from overloads and short circuits. Identified by the NB232040U part number, this unit is a component within electrical distribution systems where a 3-pole configuration and a 240V operating level are required, providing a defined protection threshold at 40 amperes. The 3-pole design means three separate conductors are controlled by the device, allowing it to protect multi-line circuits, while the 240V rating indicates the voltage at which the device is intended to operate safely. As part of Federal Pacific Electric’s NB-series, the NB232040U communicates a specific rating and pole arrangement, offering a straightforward 40A protection option for applications that demand a 3P, 240V breaker. Because this description reflects the listed model and ratings only, ensure that the panel, wiring, and local electrical codes align with this unit’s specifications before installation.
