Square D QO2100CP 100A Double Pole Circuit Breaker 240V

Product Description

The Square D by Schneider Electric QO2100CP is a double pole circuit breaker rated at 100 amps and 240 volts, designed for overcurrent protection in residential and light commercial electrical panels. This breaker interrupts circuit continuity when current exceeds its rated capacity, protecting wiring and connected equipment from damage due to overloads or short circuits. Sold individually, it is installed by licensed electricians during panel upgrades, service replacements, or new circuit installations. The QO series is a widely recognized format in the electrical trade, and this 100-amp, 2-pole configuration handles demanding loads such as electric ranges, dryers, HVAC equipment, and subpanel feeds.

This circuit breaker is suited for 240-volt double pole applications in residential main panels, subpanels, and light commercial distribution boards. The bulk packaging format makes it appropriate for service calls and contractor stock. The 100-amp rating positions it as a standard choice for high-draw appliance circuits and equipment branch circuits where a dedicated double pole breaker is required by code.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel at the utility disconnect or main breaker before handling any internal components. Verify that the load center is rated to accept QO series breakers before installation. Do not exceed the breaker ampere rating when sizing branch circuit conductors.
