Square D QOB230GFI - 30A, 2-Pole, GFCI Ground-Fault Circuit Breaker

Meet the Square D QOB230GFI—a 30A, 2-Pole GFCI ground-fault circuit breaker engineered to bring safer, more reliable protection to industrial, commercial, and OEM electrical systems. Designed for use in panelboards, switchboards, and control panels, this breaker delivers dependable overcurrent protection while adding critical ground-fault sensing to keep operators safe and equipment protected.

Why choose the QOB230GFI for your distribution and control applications

• Precise, two-hot-lead protection: The 2-Pole configuration protects multiwire circuits and 240V machinery by monitoring for ground faults across both conductors, interrupting power when leakage is detected.
• 30-amp circuit protection: Calibrated for common equipment feeders, feeders to motor starters, and light-to-medium loads in commercial environments, helping prevent overheating and nuisance trips on normal loads.
• GFCI safety in demanding environments: Ground-fault protection reduces the risk of electric shock and equipment damage in wet or damp locations, washdown areas, and other high-risk settings where safety matters most.
• Easy integration with Square D systems: Built to fit the QOB family’s form factor, enabling straightforward replacement or upgrade in existing panelboards, switchboards, and control panels without extensive rewiring.
• Versatile for industrial, commercial, and OEM needs: Ideal for distribution panels and motor control centers where reliable, code-forward protection and consistent performance are essential.

Practical use cases and scenarios

Use the QOB230GFI in electrical rooms serving conveyors, pumps, HVAC equipment, and processing line machinery where a ground fault could pose safety risks or cause equipment damage. It’s well-suited for panelboards in manufacturing floors, commercial facilities with exposed wet environments, and OEM assemblies requiring compact, dependable leakage protection without compromising on space or compatibility.
