NE231020 - 20Amp Circuit Breaker

NE231020 - 20Amp Circuit Breaker

The NE231020 is a 20 amp, three-pole bolt-on circuit breaker designed for dependable protection in three-phase electrical systems. Built with a thermal magnetic trip mechanism, this molded case circuit breaker helps protect wiring and connected equipment from overloads and short circuits. It’s commonly used in commercial and light industrial panelboards where consistent performance and secure installation matter. With its bolt-on mounting style, the NE231020 provides a firm connection to the panel bus, helping reduce the risk of loose contacts over time.

If you’re maintaining or replacing a breaker in an existing NE frame panel, this model is designed to fit properly and perform as expected under its rated conditions. Its compact footprint makes it suitable for panels where space is limited, while still delivering the protection required for 20 amp three-phase circuits.
