NM632600 - 600Amp Circuit Breaker

NM632600 - 600Amp Circuit Breaker

The NM632600 is a 600 amp, 3-pole molded case circuit breaker that’s typically used in larger electrical systems where dependable overcurrent protection is expected. It’s most often installed as a replacement during maintenance work, especially in commercial or industrial panels that carry heavy electrical loads. The breaker uses a standard thermal-magnetic trip, so it responds to overloads over time and also reacts quickly to short circuits when they occur. It installs using a bolt-on connection and comes with load-side lugs already in place, which helps keep the install process simple and familiar for electricians working on existing equipment.
