All QO circuit breakers are equipped with the exclusive visi-trip indicator. When a QO visi-trip circuit breaker trips, the handle snaps to a midpoint position between Off and On and a highly visible, red indicator easily identifies the tripped breaker. This enables you to easily distinguish which breaker has tripped in a load center that may contain up to 42 different circuit breakers. | Schneider Electric | | Square D QO 20 amps Plug In 2-Pole Circuit Breaker | Best Buy
