The industry leader in circuit protection is easily recognized by the industry's only trip indicator—the red Visi-Trip® Indicator makes it easy to spot a tripped circuit breaker. Compact 3/4 in wide format for one-pole circuit breakers helps minimize panel space and footprint. The Square D® exclusive Qwik-Open® protection is standard on all 15 A and 20 A circuit breakers— trip reaction within 1/60th of a second. No other circuit breaker trips faster.
