Lighting and receptacle circuits in homes and light commercial buildings need a dependable 15 A branch breaker that shows clearly when it has tripped. The Square D QO115 is a 1-pole, 15 A, 120/240 VAC plug-in miniature circuit breaker with a 10 kA interrupting rating, made for Square D QO load centres. Its thermal-magnetic trip and Visi-Trip indicator make it the standard replacement breaker in QO panels.

Pro tip from the counter
When a circuit is dead, look for the red Visi-Trip flag in the handle window instead of pushing every handle, because a tripped QO handle only sits slightly off the ON position. To reset, push the handle firmly all the way to OFF first, then back to ON; if it trips again right away, have an electrician find the fault before resetting it again.
Best for: residential lighting and receptacle circuits, QO panel replacements and additions, light commercial branch circuits, service and repair calls
