NFJ631200 - 200Amp Circuit Breaker

NFJ631200 - 200Amp Circuit Breaker

The NFJ631200 is a 200 amp, 3-pole molded case circuit breaker commonly used in commercial and industrial electrical systems. It’s designed for situations where dependable overload and short-circuit protection is needed without adding unnecessary complexity to the panel. The thermal magnetic trip responds to electrical faults in a predictable way, which is why this breaker is often selected for maintenance or replacement work. With a bolt-on mounting style and load-side lugs, it installs cleanly and stays secure once in place. For electricians and maintenance crews, that means fewer issues during installation and fewer callbacks later.
