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.

    • two alignment tabs
Size: Pack of 1
This perfect, fits just like the old one and does have two clips at the base to snap on to the alignment bar. I ordered a 30 amp from another vendor and it only has one of the alignment clips for a double breaker. I am very happy with this breaker, no knock-off here, it is the real thing!

    • The Square D HQ series is one the most respected Breaker Panels
Size: Pack of 1
I installed a Square D Breaker Panel at several projects during the past 30 years. All have been outstanding, safe, well designed and very durable. I only use the panels that accept "HQ" breakers and have never been disappointed.

This is the QO240CP. It's a 40 Amp brake, I will use it to run an air compressor (Ingersoll suggested this 40Amp) See the attached pictures, it really helps seen the back, the place when the lines attached to it and the front of it.
