Square D QOB220GFI - 20A, 2-Pole, GFCI Ground-Fault Circuit Breaker

Meet the Square D QOB220GFI — a 20A, 2-Pole GFCI ground-fault circuit breaker crafted for demanding electrical environments. This unit combines reliable overcurrent protection with integrated ground-fault sensing, tripping quickly to minimize shock risk and protect both personnel and equipment in distribution panels and motor control centers.

Key features that set the QOB220GFI apart

• 20A current rating with a 2-Pole configuration, suitable for circuits that use two hot legs in 120/240V systems and related panel layouts.
• GFCI (ground-fault) protection built into the breaker, providing automatic disconnection when leakage current is detected to enhance safety and reduce the chance of shock.
• Flexible integration in panelboards, switchboards, and control panels, helping simplify wiring and cabinet layouts in complex electrical rooms.
• Specifically designed for industrial, commercial, and OEM applications where dependable protection and safe operation are critical in distribution panels and motor control centers.

Where this breaker shines

• Industrial control panels and motor control centers that require fast, reliable ground-fault interruption alongside overcurrent protection.
• Commercial electrical rooms and equipment enclosures where protecting personnel and sensitive equipment from ground faults is a priority.
• OEM installations that demand a compact, integrated solution to meet safety codes without adding extra components.

Why choose this 2-Pole GFCI breaker for your system

Unlike traditional breakers that only manage overcurrent, the Square D QOB220GFI delivers ground-fault protection in the same compact form factor. This means fewer components, easier panel design, and a clearer path to meeting safety standards in critical electrical infrastructure. Its 2-Pole design ensures comprehensive protection across both hot conductors in multi-wire or 240V circuits, helping you maintain safe operation across your distribution panels and MCCs.
