Square D QOUQ225 225A 2-Pole 240 V Circuit Breaker

The Square D QOUQ225 225A 2-Pole 240 V Circuit Breaker is built to safeguard heavy 240V circuits with reliable, fast-acting overcurrent protection.

• Part Number: QOUQ225
• Current rating: 225 A
• Poles: 2
• Voltage rating: 240 V

Why the QOUQ225 stands out for demanding electrical systems: a true two-pole design that disconnects both hot legs simultaneously, reducing the risk of arc and shock on 240V circuits. With a 225 A rating, this breaker is purpose-built for high-current feeders and large loads, delivering dependable protection where it matters most in commercial and industrial panels.

• Rugged, long-lasting construction designed for challenging environments and demanding service conditions.
• Easy integration into compatible Square D panels and enclosures that support QOUQ-series breakers, minimizing downtime during upgrades or replacements.
• Clear, straightforward identification for fast troubleshooting and maintenance in busy electrical rooms.
• Effective short-circuit interruption helps shield cables, motors, and associated equipment from damaging faults.

Ideal use cases

• Feeder protection for large 240V loads such as HVAC equipment, compressors, pumps, and industrial motors in commercial facilities.
• Main feeder disconnects in service panels where high-current protection is required.
• Replacement breaker in existing Square D installations that demand robust 225A, 2-pole 240V protection.

Practical installation notes: ensure panel compatibility with QOUQ-series breakers, confirm the 240 V, 2-pole configuration matches your system requirements, and verify conductors and terminations are rated for up to 225 A continuous current. Proper sizing and safety practices help maximize protection and minimize downtime in critical electrical systems.
