Square D QO245GFI - 45A, 2-Pole, Circuit Breaker

Meet the Square D QO245GFI — a 45A, 2-Pole Circuit Breaker designed to deliver dependable overcurrent protection in demanding electrical environments. Built on the Square D QO platform, this breaker integrates seamlessly with panelboards, switchboards, and motor control centers, offering flexible protection for a range of 240V circuits.

• Two-pole configuration protects two hot conductors and guarantees a simultaneous trip, preventing neutral or grounding issues in 240V circuits.
• 45A current rating is ideal for feeders and branch circuits in commercial, industrial, and OEM installations where steady, predictable protection is required.
• Plug-on mounting into compatible QO panelboards enables fast, secure installation with minimal tools.
• Durable construction built for the rigors of daily use in distribution panels and motor control centers.
• Provides reliable overcurrent protection, reducing the risk of wiring damage and electrical fires while enabling fast isolation of faulted circuits.

Where this breaker shines

• Industrial environments with multiple feeders and critical loads, such as manufacturing lines, conveyors, and automated equipment.
• Commercial distribution panels supporting HVAC, lighting, and power circuits that require streamlined protection solutions.
• OEM applications where a compact, dependable 2-pole breaker is needed to fit within standard enclosures and back panels.

Design, compatibility, and daily use

• Part of the QO family, renowned for reliable performance and straightforward installation in Square D systems.
• Suitable for use in distribution panels, switchboards, and control panels that rely on consistent, code-compliant overcurrent protection.
• Clear, immediate trip indication and simple one-hand reset support quick maintenance checks and safe servicing.

Practical guidance for selection and installation

• When replacing or expanding, choose a 2-pole 45A unit that matches your existing QO panel’s mounting and bus configuration for a smooth fit.
• Ensure the circuit’s protection needs align with the breaker's rating to maintain safe, compliant operation across your panel network.
• Use in systems that require simultaneous disconnection of both conductors to meet safety requirements for 240V circuits.

With the Square D QO245GFI 45A 2-Pole Circuit Breaker, you gain a reliable shield for critical loads, streamlined installation, and a robust solution tailored to panelboards, switchboards, and motor control centers in industrial, commercial, and OEM settings.
