NB221020 - 20Amp Circuit Breaker Description
NB221020 - 20Amp Circuit Breaker
The NB221020 20A double pole circuit breaker is a straightforward, dependable option for protecting 120/240V electrical circuits. Designed with a thermal magnetic trip, it automatically shuts off power when a circuit is overloaded or when a short circuit occurs. That quick response helps protect wiring, connected equipment, and the overall panel from damage. With a 20 amp rating and a 10kA interrupting capacity, this breaker is commonly used in residential and light commercial applications where consistent, properly rated protection is required. The bolt-on design secures the breaker firmly in place, helping ensure a solid connection inside compatible panels.
