THQL1120GFT - 20Amp GFCI Circuit Breaker

THQL1120GFT - 20 Amp Single Pole GFCI Circuit Breaker

The THQL1120GFT is a 20 amp, single pole Q-Line circuit breaker engineered to provide dependable overcurrent protection along with built-in 5mA ground fault circuit interrupter (GFCI) functionality. Designed for 120VAC systems and rated at 10kA A.I.C., this molded case breaker helps safeguard both electrical equipment and personnel by quickly interrupting power during overloads, short circuits, or ground faults. Its plug-on design allows for straightforward installation in compatible load centers, making it a practical solution for residential and light commercial applications where code-compliant ground fault protection is required. As part of the THQL-GFT frame family, this breaker combines thermal-magnetic trip performance with sensitive ground fault detection. The HACR rating also supports use in heating, air conditioning, and refrigeration equipment circuits, giving electricians and facility managers added flexibility when selecting protection for HVAC-related loads. Compact yet durable, the THQL1120GFT is built to meet demanding electrical standards while maintaining ease of integration into Q-Line panelboards.
