Square D QO220C 20A Double Pole Circuit Breaker 240V

Product Description

The Square D QO220C is a 20-amp double-pole circuit breaker rated for 240 volts, designed for use in QO-style load centers and panelboards. It provides overcurrent protection for 240-volt branch circuits by interrupting power when current exceeds the rated threshold. The breaker ships in a recloseable clamshell package and is sold in a package quantity of 3. Licensed electricians install this breaker during new construction, panel upgrades, or circuit replacement work in residential and light commercial applications.

The QO220C is suited for 240-volt branch circuit protection in residential and light commercial electrical panels. Common applications include dedicated circuits for electric dryers, water heaters, air conditioning equipment, and other double-pole loads requiring 20-amp overcurrent protection. Its double-pole configuration interrupts both ungrounded conductors simultaneously, which is required for 240-volt circuits under NEC guidelines.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always shut off main power to the panel before installing or replacing a circuit breaker. Verify that the panel is a QO-compatible load center before installation. Do not install in panels rated for a different breaker series, as improper fit can result in a hazardous connection.
