NA50 - 50Amp Circuit Breaker

NA50 - 50Amp Circuit Breaker

If you need a dependable 50 amp single-pole circuit breaker for a compatible Stab-Lok panel, the Schneider Electric NA50 is built to handle the job. Rated for 120V AC systems, this breaker helps protect branch circuits from overloads and short circuits before damage can occur. With a 10 kA interrupting rating, it’s designed to safely stop higher fault currents that can happen in residential and light commercial environments. The plug-in Stab-Lok style makes installation straightforward, while the solid screw terminal connections support both copper and aluminum conductors for flexible wiring setups.
