THQL1115DF - 15Amp Dual Function Circuit Breaker

THQL1115DF - 15 Amp Dual Function Circuit Breaker

The THQL1115DF is a 15-amp, single-pole, dual-function molded case circuit breaker engineered to deliver dependable circuit protection in residential and light commercial electrical systems. Designed as part of the trusted THQL Q-Line series, this plug-on breaker combines GFCI (Ground Fault Circuit Interrupter) and AFCI (Arc Fault Circuit Interrupter) protection in a single compact unit—helping safeguard people and property from electrical hazards. With a 10k A.I.C. rating at 120VAC, the THQL1115DF is built to interrupt fault currents effectively while maintaining consistent performance in standard branch circuit applications. Its HACR rating also makes it suitable for heating, air conditioning, and refrigeration equipment circuits where code compliance and reliability are critical.

If you’re upgrading a panel, replacing an existing breaker, or meeting current NEC requirements for arc fault and ground fault protection, the THQL1115DF offers a space-saving, efficient solution. The plug-on design allows for straightforward installation into compatible Q-Line load centers, while the dual protection functionality reduces the need for separate protective devices—streamlining your panel layout without sacrificing safety.
