NEF431015 - 15Amp Circuit Breaker

NEF431015 - 15Amp Circuit Breaker

The NEF431015 circuit breaker is a 3-pole, 15 amp thermal magnetic molded case circuit breaker designed to protect three-phase electrical systems from overloads and short circuits. Built on the NEF frame platform, this bolt-on breaker delivers dependable circuit protection in commercial and industrial power distribution setups. With voltage ratings up to 480VAC and solid interrupting capacity, it’s a practical choice for maintaining existing electrical equipment and keeping systems operating safely. Electrical protection isn’t something you want to second guess. The NEF431015 responds to prolonged overloads through its thermal mechanism and reacts instantly to short circuits using its magnetic trip function. That combination helps reduce the risk of equipment damage, unexpected downtime, and costly repairs. Its bolt-on design provides a secure connection inside compatible panelboards or switchboards, helping ensure stable performance over time.
