SIEMENS Q220GF Ground Fault Circuit Interrupter, 20 Amp, 2-Pole – Replaces QF220A

Overview

The Siemens Q220GF is a 20-amp, 2-pole ground fault circuit interrupter designed for 120/240-volt systems. It adheres to UL Listed and cUL Certified standards, delivering Class A GFCI protection for circuits where safety and reliability matter across residential and light commercial settings.

Self-Test, Lockout and Reliable Protection

Engineered with automatic Self-Test and Lockout features per UL 943, the GFCI continuously checks itself to help ensure proper operation. If the device is ever compromised, it trips and signals for replacement, supporting ongoing fault protection without constant manual checks. A current imbalance of 4-6 mA or more between load conductors triggers the trip mechanism, reducing the risk associated with undetected faults on protected circuits.

These design choices aim to provide dependable protection in everyday environments where water exposure or moisture may be present, without promising guaranteed outcomes, but with a clear path toward safer operation.

Design, Compatibility and Capacity

The Q220GF features a reduced profile that creates additional space for wire bending in crowded panels, making installations smoother and neater. It is a 2-pole device suitable for 120/240-volt AC systems and replaces Siemens models QF220AP and QF220A, providing a straightforward upgrade path for existing installations. With a 10,000 AIR rating, it is built to handle typical surge and fault scenarios in demanding environments.

• UL Listed and cUL Certified for reliability and compliance
• LED indicators help identify fault conditions at a glance
• Compact form factor frees up space and improves wiring flexibility

Ideal Use Locations

Specifically suited for wet and damp locations, this breaker is well suited for pools, spas, HVAC equipment, kitchens, and bathroom circuits. In homes or light commercial spaces, it can be a practical choice wherever water exposure or moisture is a concern, offering a balance of protection and convenience.

• Great for kitchens, bathrooms, and spa-related equipment
• Suitable for pool or spa equipment and other moisture-prone installations

What to Expect in Your Panel

Designed for seamless integration with standard electrical panels, the Q220GF supports 120/240-volt systems and offers robust ground fault protection across multi-wire branch circuits. It serves as a reliable upgrade option when replacing older 2-pole GFCI breakers.
