NJL631200 - 200Amp Circuit Breaker

The NJL631200 200 amp circuit breaker is built for situations where you need dependable protection without overthinking the install. Designed for maintenance and replacement work, this three-pole breaker helps protect electrical systems from overloads and short circuits while handling higher current demands with ease. The bolt-on mounting style keeps the breaker firmly seated once installed, and the thermal magnetic trip mechanism reacts quickly when current levels move outside safe limits. With load-side lug terminals already included, this breaker fits cleanly into many existing setups and helps keep downtime to a minimum.
