NEF421015 - 15Amp Circuit Breaker Description
NEF421015 - 15Amp Circuit Breaker
The NEF421015 15 amp 2-pole circuit breaker protects commercial and industrial electrical systems from overloads and short circuits. Designed for NEF frame panelboards, this molded case circuit breaker uses a thermal magnetic trip unit to detect sustained overcurrent conditions and respond instantly to short circuits. It helps prevent damage to wiring and connected equipment while supporting safe, consistent system performance. The bolt-on mounting style allows electricians to secure the breaker firmly into place, making it a reliable choice for replacing an existing breaker in a compatible panel.
