THQB1120GFT - 20Amp Circuit Breaker

THQB1120GFT - 20 Amp Circuit Breaker

The THQB1120GFT is a 20-amp, 1-pole ground fault circuit interrupter (GFCI) circuit breaker designed to provide both dependable circuit protection and enhanced personnel safety in your 120VAC electrical systems. As part of the trusted THQB Q-Line series, this bolt-on circuit breaker helps you to protect against overloads, short circuits, and potentially dangerous ground faults that can occur in residential, commercial, and light industrial applications. Featuring a 10kA interrupting capacity at 120VAC, the THQB1120GFT is engineered for installations where reliable fault protection is essential. Its integrated Ground Fault Circuit Interruption (GFCI) functionality helps you detect leakage currents and quickly disconnect power when ground fault conditions are present, reducing the risk of electrical shock. The compact bolt-on design provides a secure connection within compatible panelboards, while its HACR rating makes it suitable for use in heating, air conditioning, and refrigeration applications. Whether you're upgrading an existing electrical system or replacing a breaker in a Q-Line panel, the THQB1120GFT offers a practical combination of protection, safety, and dependable performance.
