Square D QO250GFI - 50A, 2-Pole, GFCI Ground-Fault Circuit Breaker

Meet the Square D QO250GFI — a 50A, 2-Pole GFCI Ground-Fault Circuit Breaker engineered for demanding industrial, commercial, and OEM environments. This breaker delivers reliable overcurrent protection with integrated ground-fault sensing to help keep people and equipment safe in distribution panels, motor control centers, panelboards, and switchboards.

Why this matters for your project

• Ground-Fault Protection — detects even small leakage differences between conductors and neutral, tripping swiftly to isolate the fault and reduce shock risk in damp or exposed environments.
• 50 Amp, 2-Pole Design — provides robust protection for high-load circuits while ensuring a simultaneous trip on both hot legs for enhanced safety and coordination with other protective devices.
• Versatile Compatibility — specifically suited for use with Square D QO panelboards and switchboards, offering a streamlined replacement or installation path in existing systems.
• Ideal for Critical Applications — well-suited for distribution panels and motor control centers in industrial facilities, commercial buildings, and OEM applications where dependable protection matters most.

Practical use cases and scenarios

• Installing on circuits that feed equipment in wet, humid, or wash-down areas where ground-fault protection is important for safety.
• Upgrading older electrical rooms to modern safety standards by adding GFCI protection to high-current branch circuits.
• Integrating into OEM assemblies where reliable, code-responsive protection is required for distribution panels and control centers.

What you gain by choosing this breaker

• Enhanced personnel safety through rapid interruption of fault currents.
• Protection for valuable equipment from ground faults and insulation failures, helping reduce downtime and maintenance costs.
• A dependable, straightforward solution that aligns with existing Square D QO systems, reducing installation complexity and setup time.

In short, the Square D QO250GFI delivers precise 50A, 2-Pole GFCI protection tailored for environments where safety and reliability can’t be compromised.
