Square D | QGA222252 | Circuit Breaker | 225A | 2-Pole | 240V | 65kA

Square D QGA222252 delivers reliable, high-capacity protection for demanding electrical systems. This 225A, 2-pole circuit breaker operates at 240V and offers a 65kA interrupting rating, making it suitable for commercial and light industrial panels where robust fault protection is critical. Use this part when you need a precise match for replacement, retrofit, or maintenance projects and when the panel requires QGA-series compatibility.

Key specifications

• Amperage: 225 A
• Poles: 2-Pole
• Voltage: 240 V
• Interrupting rating: 65 kA
• Part number: QGA222252

Where and how you’ll use it

Ideal for replacing a failed breaker in Square D distribution panels, retrofitting older panels to handle higher fault currents, or integrating into new installations that demand a 225A, 2-pole device. The 240V rating aligns with standard 120/240V service panels found in many commercial buildings and industrial sites.

Why this matters

The 65kA interrupting capacity provides a margin of safety against high-energy faults. For facilities with critical loads—HVAC systems, motors, lighting, and controls—a breaker with this rating helps prevent collateral damage and reduces downtime by quickly isolating faults. The 2-pole design ensures both hot legs trip together, preserving system balance and simplifying protection coordination.

Fit, compatibility and installation tips

• Always confirm fit and ratings before ordering. The part number QGA222252 is the best reference for compatibility.
• Verify your panel accepts QGA-series breakers and that the voltage and interrupting rating match your service conditions.
• Follow manufacturer wiring and torque specifications during installation and observe all safety protocols.

Who benefits most

Electrical contractors, maintenance engineers, and facility managers working in commercial facilities, data centers, manufacturing floors, or campus buildings will appreciate the precise fit, robust interrupting capacity, and clear replacement path this breaker provides.
