Square D QO220CP 20A Double Pole Circuit Breaker 240V

Product Description

The Square D QO220CP is a 20-amp, double pole circuit breaker rated for 240 volts, designed for use in QO-series load centers and panel boards. It provides overcurrent protection for 240-volt branch circuits by interrupting power when current exceeds the rated ampacity. The double pole configuration handles two-pole loads such as HVAC equipment, water heaters, electric dryers, and subpanels. Sold in bulk packaging with 5 units per package, the QO220CP is a practical choice for electrical contractors stocking panels or completing multiple rough-in installations at once.

This breaker is suited for residential and light commercial electrical systems where QO-series panel hardware is already installed. Typical applications include branch circuit protection for 240-volt HVAC systems, resistance heating units, well pumps, and similar two-wire loads. The bulk pack format reduces per-unit cost and simplifies inventory management for electricians handling multi-unit projects or service work across multiple panels.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (National Electrical Code) and all applicable local codes. Always shut off the main breaker and verify the panel is de-energized before installing or replacing any circuit breaker. Confirm the panel is a QO-series load center before inserting the breaker to ensure proper bus engagement. Do not exceed the panel's total ampacity or the number of breaker spaces specified by the panel manufacturer.
