Square D QO230GFI - 30A, 2-Pole, GFCI Ground-Fault Circuit Breaker

Meet the Square D QO230GFI — a 30A, 2-Pole GFCI ground-fault circuit breaker engineered for dependable overcurrent protection with built-in ground-fault sensing. Designed to slot into Square D’s QO family, this unit delivers precise protection in panelboards, switchboards, and control panels across industrial, commercial, and OEM environments.

• Current rating: 30A for reliable protection of circuits that require stronger interrupting capacity.
• Poles: 2-Pole configuration ensures simultaneous disconnection of both hot legs, enhancing safety and revert protection in multi-wire applications.
• Breaker type: GFCI Ground-Fault Circuit Breaker, integrating ground-fault protection with standard overcurrent protection to quickly isolate faulted circuits.
• Applications: Ideal for panelboards, switchboards, and control panels in industrial settings, commercial installations, and OEM equipment where robust, safe operation is critical.

This GFCI breaker is purpose-built for environments where ground faults pose a real risk to people and equipment. By detecting imbalances between live conductors, it interrupts power before a fault can cause harm or damage, giving operators peace of mind in critical distribution points and motor control centers.

Key benefits and practical use cases

Whether you’re wiring a warehouse conveyor circuit, a pump station, or a control panel for automated equipment, the QO230GFI provides:

• Quick disconnection on ground faults protects personnel from shock and reduces the potential for equipment damage.
• Simplified protection strategy: A single device covers both overcurrent and ground-fault protection, streamlining panel layouts and maintenance checks.
• Versatile integration: Fits in standard QO-series installations, making it a straightforward upgrade or retrofit for existing panels.
• Reliability in demanding environments: Built to perform in commercial and industrial panels where consistent protection is essential.

Best-fit scenarios

The Square D QO230GFI is particularly well-suited for:

• Distribution panels in manufacturing floors where motor loads are present and fault exposure must be mitigated.
• Commercial electrical rooms and equipment rooms requiring enhanced safety on vital circuits.
• OEM panels where a compact, all-in-one protection solution simplifies design and compliance.

Choosing the QO230GFI means selecting a trusted, purpose-built GFCI breaker that combines the familiarity of the QO form factor with proactive ground-fault protection. It’s the pragmatic choice for safer, more reliable electrical distribution in the systems you rely on every day.

Note for installers and specifiers: Verify panel compatibility with QO-series devices and ensure proper alignment for a secure, code-compliant installation. This 2-Pole configuration provides coordinated interruption of both hot conductors, delivering a safer shutdown in fault conditions.
