Square D QO230C 30A Double Pole Circuit Breaker 240V

Product Description

The Square D QO230C is a 30-amp, double-pole circuit breaker rated for 240 volts, designed for residential and light commercial electrical panels. It provides overcurrent and short-circuit protection for 240-volt branch circuits, interrupting power to both hot legs simultaneously when a fault is detected. The breaker ships in a recloseable clamshell package and is sold in a package quantity of 3. Licensed electricians install this breaker as part of service panel builds, subpanel feeds, and dedicated appliance circuit work. At 2 pounds per unit, it is a standard form-factor breaker suited to QO-series load centers.

The QO230C is used in residential load centers and light commercial electrical panels where a double-pole, 30-amp branch circuit is required. Typical applications include electric dryers, water heaters, HVAC disconnect circuits, and other 240-volt dedicated loads. It is well suited for new construction panel builds as well as panel upgrade and service replacement work where a QO-series breaker position is available.

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 and verify absence of voltage with a meter before handling any bus or wiring connections. Confirm the load center is rated for QO-series breakers before installation. Do not exceed the breaker ampere rating or the conductor ampacity of the connected circuit wiring.
