THQL1120GFT - 20Amp GFCI Circuit Breaker

THQL1120GFT - 20Amp GFCI Circuit Breaker

When you’re dealing with electrical safety, you don’t want “good enough.” The THQL1120GFT ABB 20 Amp GFCI circuit breaker is built for situations where protection matters—plain and simple. Designed for residential and light commercial panels, this breaker helps guard against ground faults by cutting power the moment something isn’t right. That’s the kind of protection you want in kitchens, bathrooms, garages, and anywhere moisture can turn into a real hazard.

This model is part of ABB’s trusted Q-Line series, known for its straightforward installation and dependable performance. It’s a plug-in style breaker, so it seats cleanly into compatible load centers without fuss. Once installed, you get the benefit of a thermal-magnetic trip system, which handles both overloads and short circuits with consistency. On top of that, the quick-make/quick-break mechanism helps ensure the breaker reacts fast when it needs to—no hesitation.

Another small but important detail: the trip indicator is easy to spot. That saves time when you’re troubleshooting, especially in a busy panel. It’s one of those features you don’t think about until you need it—and then you’re glad it’s there.
