Overview

The ABB Electrification THQB1120GFT is a 1-pole, 20 Amp Q Line plug-in circuit breaker designed for residential and commercial applications. This thermal-magnetic device features a compact, one-inch wide per pole design, making it ideal for integration into ABB and GE load centers, meter combos, and lighting panels. As a plug-in variant of the Q Line, it offers simplified installation and connection to bus bars. The THQB1120GFT breaker is built to UL and cUL standards (UL 489) and boasts an interrupting rating of 10,000 AIC. Key features include Quick-make / Quick-break mechanisms for rapid and reliable circuit interruption, common trip bars for simultaneous pole operation, and easily visible trip indication for quick fault identification. This specific model is rated for 120 Vac. Optional accessories such as auxiliary contacts and shunt trip units can be ordered separately to enhance functionality, and the Q Line breakers are also available for High-Intensity Discharge (HID) applications. The THQB1120GFT is suitable for HACR (heating, air conditioning, and refrigeration) applications. The Q Line circuit breakers, including the THQB1120GFT, are known for their safety and reliability due to these integrated mechanisms. The 0GFT designation signifies the 20 Amp rating for this particular breaker. The plug-in design specifically caters to efficient connection within load centers and lighting panels, a hallmark of the QL breaker series. The common trip bars ensure that in the event of a fault, all poles are disconnected simultaneously, further enhancing safety. The easily spotted trip indication provides a clear visual cue when the breaker has operated, simplifying troubleshooting and maintenance. The availability of accessories allows for customization to meet specific application needs, whether it's monitoring circuit status with auxiliary contacts or remote tripping capabilities with shunt trip units. The Q Line's versatility extends to specialized environments like HID applications, demonstrating its robust design. Manufacturer: ABB - Electrification. SKU: THQB1120GFT.
