THQL1120DF - 20Amp Dual Function Circuit Breaker Description
THQL1120DF - 20 Amp Dual Function Circuit Breaker
The THQL1120DF is a 20-amp, single-pole dual-function circuit breaker designed to protect 120V branch circuits in residential and light commercial panels. It combines AFCI (arc fault) and GFCI (ground fault) protection into one breaker, helping protect both wiring and people from common electrical hazards. Instead of installing separate devices, this all-in-one solution simplifies the job while helping you meet modern code requirements.
Built on the THQL-DF Q-Line platform, this breaker features a convenient plug-on design for quick installation in compatible load centers. With a 10k A.I.C. rating at 120VAC, it’s engineered to safely interrupt short circuits while maintaining consistent performance. It’s also HACR rated, making it suitable for heating and air conditioning applications where that rating is required.
If you’re upgrading a panel or replacing an existing breaker, the THQL1120DF offers dependable protection without adding unnecessary complexity.
