QBGF1020 - 20 Amp Circuit Breaker

Eaton QBGF1020 Ground Fault Circuit Breaker (20 Amp, Single‑Pole)

If you’re looking for reliable protection against ground faults in your electrical panel, the Eaton QBGF1020 Ground Fault Circuit Breaker (20 Amp, Single‑Pole) is engineered to deliver peace of mind. It senses current leakage (as small as 5 mA) and quickly interrupts the circuit, which helps prevent shock and fire risks. Designed for 120/240‑volt systems and with a 10 kAIC interrupt capability, it handles fault events without failing. Because it’s a bolt‑on style breaker with non‑interchangeable trip components, you get consistent installation and performance. Whether you’re a professional electrician or doing serious DIY work, this breaker gives you solid protection and simple integration.

Key Features and Benefits

• Ground Fault Detection: Detects even very small leakages (5 milliampere sensitivity) and shuts off power rapidly to protect people and property.
• Strong Interrupting Capacity: Rated to break fault currents up to 10 kiloamps – built to handle stressful conditions without damage.
• Bolt‑On Design: Securely attaches to compatible Eaton panel boards, making installation safe and straightforward.
• Single‑Pole Configuration: Saves panel space and is ideal for switching/protecting individual branch circuits.
• Non‑Interchangeable Trip Mechanism: Prevents incorrect replacement parts from being used, maintaining safety and code compliance.

Material Compliance and Certifications

• This breaker meets or exceeds established safety and manufacturing standards. It is UL‑489 certified, which is the standard for molded‑case circuit breakers and ensures the device passes rigorous safety and performance tests.
• It is manufactured by Eaton / Cutler‑Hammer, a company with long‐standing reputation in electrical protection equipment.
• For wire connections and components, material is chosen to resist degradation, heat, and electrical stress. Some versions are treated for moisture or fungus resistance, which improves durability in harsh environments.

Where It Works Best

• Bathrooms, kitchens, laundry rooms, or any location where water or moisture is present, because ground fault protection is especially important there.
• Outdoor circuits, garages, or workshops, where exposure to dampness or fluctuating humidity could pose risks.
• Commercial locations with panel boards that need single‑pole ground fault protection, such as retail stores, small offices, or food service areas.
• For homeowners or maintenance professionals doing upgrades to meet modern electrical safety codes; this breaker helps you comply with NEC (or your local regulations) regarding ground fault protection.
