## Description

Product Description The Square D by Schneider Electric QO 40 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. From the Manufacturer Full size 3/4" breakers, 120/240 Volts ac; 10,000 AIR. U.L. Listed as HACR type for use with equipment having motor group combinations and marked for HACR breakers.

Review: High quality genuine Square-D breaker for QO panel, no issues - Fits QO load center and operates as advertised, no issues, and about $10 less than at local Home Despot and Loew's, if you're willing to wait 5-10 days for free shipping. Screw contacts for load wires are "new improved" half-conical design vs. the older "flat crusher" style in older designs, which is a nice improvement especially for stiff 6-ga Al stranded wire. Screw threads are combo standard+philips cross, with sufficiently deep slots that it's easy to tighten them down hard. In short, it's a standard Square-D quality breaker, no surprises.
