NM632700 - 700Amp Circuit Breaker

NM632700 - 700Amp Circuit Breaker

The NM632700 is a 700 amp, 3-pole molded case circuit breaker used in commercial and industrial power systems where high current and dependable protection are required. It’s built for applications that run heavy loads and need a breaker that reacts correctly when something goes wrong. The thermal magnetic trip helps protect equipment from overloads and short circuits without being overly sensitive during normal operation.

This breaker mounts using a bolt-on design, which makes it easier to install during maintenance or replacement work. Load-side lug terminals are included, so there’s no guessing or retrofitting just to make proper connections. With a 40°C temperature rating and an NM frame, the NM632700 fits well into existing systems that already call for this style and size of breaker.
