THQL1120AF - 20Amp Circuit Breaker

THQL1120AF - 20 Amp Circuit Breaker

The THQL1120AF is a 20-amp, single-pole circuit breaker designed for you to use in compatible Q-Line load centers. It combines standard circuit protection with Arc-Fault Circuit Interruption (AFCI) technology, which helps detect potentially dangerous arcing faults in household wiring. The plug-on design allows the breaker to seat directly onto the panel bus for a secure connection, making it a practical replacement when maintaining existing electrical systems. With a 10kA interrupting rating at 120VAC, the THQL1120AF is commonly used on branch circuits that require AFCI protection under applicable electrical codes. Its molded case construction is built for long-term service, and the compact footprint allows it to fit neatly within designated panel spaces. Whether you're replacing a damaged breaker or maintaining a Q-Line panel, this breaker provides the form, fit, and function needed for the application.
