Square D QO240CP 40A Double Pole Circuit Breaker 240V

Product Description

The Square D by Schneider Electric QO240CP is a double pole circuit breaker rated at 40 amps and 240 volts, designed for overcurrent protection in residential and light commercial electrical panels. This breaker interrupts the circuit automatically when current exceeds the rated load, protecting wiring and connected equipment from damage. Supplied in bulk packaging with a package quantity of 5 units, it suits electricians stocking service vans or completing multi-circuit jobs. Installation follows standard NEC requirements for branch circuit protection.

The QO240CP fits QO-series load centers and enclosures, making it a common choice for residential panel work, subpanel builds, and service upgrades. Double pole configuration supplies 240-volt branch circuits for equipment such as HVAC units, water heaters, dryers, and ranges. Electricians performing panel installations, service changes, or adding dedicated circuits will find this a standard-fit component for QO-series equipment.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes.
