Square D QO130C 30A Single Pole Circuit Breaker 120V

Product Description

The Square D QO130C is a single-pole circuit breaker rated at 30 amps and 120 volts, designed for use in QO-series load centers and panelboards. It occupies one space per pole and features a recloseable clamshell design that allows the breaker to be reset after tripping without requiring replacement. Licensed electricians install this breaker during new panel construction, service upgrades, or branch circuit additions. It provides overcurrent and short-circuit protection for residential and light commercial branch circuits across a wide range of applications.

This breaker is suited for residential and light commercial electrical systems where QO-series panelboard compatibility is required. Typical applications include dedicated branch circuits for appliances, HVAC equipment, lighting, and general-purpose outlets. The single-pole configuration handles standard 120-volt branch circuits. It is sold in a package of 6 units, making it practical for contractors stocking material for multiple jobs or panel installations requiring several circuits of the same amperage.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panel and verify the absence of voltage before handling or installing any breaker. Confirm the load center is rated for QO-series breakers before installation. Do not install a 30-amp breaker on branch circuit wiring that is not sized to carry that load rating.
