Square D QOU135 35A 240V 1-pole Miniature Circuit Breaker

Product Description

The SQUARE D QOU135 is a single-pole miniature circuit breaker rated at 35 amps and 240 volts AC. It provides overcurrent protection for branch circuits in residential and light commercial panelboards. The QOU135 uses box lug terminal connections and mounts directly to a compatible panel. Accepted wire sizes range from 14 to 2 AWG, giving installers flexibility across a range of conductor gauges. It meets CSA, IEC, UL, and RoHS standards, making it suitable for a broad range of protected applications. Licensed electricians install this breaker as part of panel service work or equipment circuit additions.

The QOU135 is rated for use with air conditioning, refrigeration, and heating equipment circuits. Its 35-amp rating covers many single-phase motor load and resistance heat applications common in residential and light commercial electrical systems. The panel-mount design integrates into QOU-compatible loadcenters and panelboards. This breaker is a practical choice when adding or replacing a circuit feeding HVAC equipment, electric heat strips, or similar single-phase 240-volt loads.
