NB231100 - 100Amp Circuit Breaker

NB231100 - 100Amp Circuit Breaker

The NB231100 100 Amp circuit breaker is built for dependable protection in residential and light commercial electrical panels. With a 3-pole design and a 120/240VAC rating, it helps protect wiring and connected equipment from overloads and short circuits. The bolt-on mounting style creates a tight, secure connection to the panelboard, which is especially important in applications where vibration or long-term use can loosen clip-in breakers. Whether you’re replacing a worn unit or maintaining an existing system, the NB231100 offers the steady performance electricians expect from an NB frame breaker.
