Your cart is empty.The Square D by Schneider Electric QO 45 Amp Two-Pole Circuit Breaker is intended for overload and short-circuit protection of your electrical system. The ANSI-certified and UL-listed unit is rated for 120/240 VAC and 10,000 AIR. 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. QO circuit breakers have features no other manufacturer can offer. They come in many different sizes and can meet the needs of virtually every function in your home or business. These types of quality, industry exclusive products keep the Square D brand ahead of the competition and are builders' and electrical contractors' first choice in electrical protection.

My AC stopped cooling, just blowing air, found out it was the Circuit Breaker that tripped.Each time it was switched back on, it tripped again and again every time the AC was turned on.Decided it needed to be changed. It has only this specification Square D 45 AMP, couldn't find it instore at Home Depot.Purchased it on Amazon, arrived on time, in perfect condition. Fit perfectly after removing the old one.My AC is back on cooling again.
