NE231100 - 100Amp Circuit Breaker

NE231100 - 100Amp Circuit Breaker

The NE231100 100 Amp circuit breaker is a three-pole, bolt-on molded case breaker built to protect three-phase electrical systems from overloads and short circuits. Rated at 100 amps with a 10kA interrupting capacity at 240VAC, this breaker is designed for dependable performance in commercial, industrial, and residential applications where steady, consistent protection is critical. Its thermal magnetic trip unit responds to prolonged overloads with a time-delay function and reacts instantly to short-circuit faults, helping reduce the risk of equipment damage and unexpected downtime. The bolt-on design creates a tight, secure connection to the panelboard, which helps prevent loosening over time and supports long-term reliability.
