THQL2140GF1 - 40Amp Circuit Breaker

THQL2140GF1 - 40 Amp Circuit Breaker

The THQL2140GF1 is a 40-amp, 2-pole ground fault circuit breaker used in compatible Q-Line load centers and panelboards. Rated for 120/240 VAC with a 10kA interrupting capacity, it helps you protect electrical circuits from overloads, short circuits, and ground fault conditions.

This breaker uses a plug-on design and fits applications where a THQL-series device is specified. Its HACR rating makes it suitable for use with heating, air conditioning, and refrigeration equipment. The molded case construction is built for everyday service and is intended to provide long-lasting protection in residential, commercial, and light industrial electrical systems.

Whether you're replacing an existing breaker or maintaining an installed panel, the THQL2140GF1 offers the form, fit, and function required for compatible equipment without requiring modifications to the original setup.
