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 inch 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.
A comprehensive selection of 10 kA rated circuit breakers are available including:
Plug-on QO circuit breakers are for use in QO load centers, NQ panelboards or Speed-D switchboard distribution panels. Bolt-on QOB circuit breakers are for use in NQOD panelboards.
