NC050 - 50Amp Circuit Breaker

NC050 - 50Amp Circuit Breaker

The NC050 50 Amp circuit breaker is built for dependable protection in existing electrical panels that require a higher amp rating in a compact footprint. Designed as a 1-pole, stab-on breaker, the NC050 uses a thermal magnetic trip system to respond to both sustained overloads and sudden short circuits. With a 10kA interrupting capacity at 120VAC, it is rated to safely clear fault currents while helping protect wiring and connected equipment. Its slim profile makes it a practical fit in tight load centers where every inch of space matters, and the stab-on connection helps speed up installation during routine service or replacement work.
