NC020 - 20Amp Circuit Breaker

NC020 - 20 Amp Circuit Breaker

The NC020 20 Amp circuit breaker is a straightforward, single-pole breaker designed for 120VAC branch circuits in existing electrical panels. Rated at 20 amps with a 10kA interrupting capacity, it helps shut off power when a circuit becomes overloaded or a short circuit occurs—reducing the risk of damage to wiring and connected equipment. Its slim 0.50-inch width makes it a good fit for panels where space is limited, which is often the case in older or tightly configured setups. The thermal magnetic trip design responds to both gradual overloads and sudden faults, offering dependable protection in everyday residential and light commercial use. With a stab-on mounting style, it installs directly onto the bus bar for a secure connection during replacement.
