NEF211015 - 15Amp Circuit Breaker

NEF211015 - 15Amp Circuit Breaker

The NEF211015 15 amp bolt-on circuit breaker is designed to protect a single branch circuit in 120/277VAC electrical systems. It uses a thermal magnetic trip system to help prevent damage caused by overloads and short circuits. The thermal portion reacts to sustained overcurrent conditions, while the magnetic trip responds quickly to higher fault levels. This type of protection is commonly used in commercial and light industrial panelboards where consistent, reliable circuit interruption is required. The bolt-on mounting style provides a secure connection to the bus bar, helping maintain solid contact over time.
