NE231050 - 50Amp Circuit Breaker

NE231050 - 50Amp Circuit Breaker

The NE231050 50 Amp circuit breaker is a three-pole, bolt-on thermal magnetic molded case circuit breaker designed to protect electrical systems from overloads and short circuits. Rated at 50 amps with a 10kA interrupting capacity at 240VAC, this breaker is commonly used in commercial and industrial panelboards where steady, dependable circuit protection is required. Its thermal magnetic trip unit responds to prolonged overcurrents with a time-delay action, while also reacting instantly to high-level short circuits. The bolt-on mounting style provides a tight, secure connection to the panelboard bus, helping maintain consistent electrical contact over time.
