Why customers choose TaskHolt Tools

Meet the Siemens Q220GF Ground Fault Circuit Interrupter, a 20 Amp, 2-Pole GFCI breaker designed to protect people and circuits in demanding environments. This model is UL Listed and cUL Certified, delivering Class A protection for 120/240-Volt systems.

At the heart of its performance is precise sensing: current imbalances of 4–6 mA trigger the sensor to shut off power, reducing the risk of shock in critical zones.

Self-Test and Lockout for ongoing reliability

With UL 943-compliant self-test and lockout, the Q220GF automatically tests itself and signals if it has been compromised. The device then trips to alert you that replacement may be needed to maintain protection.

Designed for professional installations, this 20A, 2-Pole unit is rated for a 10,000 AIR environment and supports 120/240-V AC systems, making it compatible with a wide range of panels and configurations.

Upgrade or replace with confidence

The Q220GF replaces older Siemens models QF220AP and QF220A, offering a modern design and updated safety features while preserving compatibility with existing wiring.

In real-world use, the compact form-factor frees more room for wire bending, making space for additional conductors in crowded panels. The LED trip indicators provide a quick visual cue when a ground fault occurs, streamlining maintenance checks.

In addition to protection, this device is well suited for installations in damp or wet locations. Think pool equipment, spas, HVAC lines, kitchen and bathroom circuits, and other areas where water or moisture is a factor. The Siemens GFCI is built to endure these environments and help keep electrical systems compliant with code expectations.
