Overview

The ABB Electrification THHQB2120GFEP is a 1-pole, 20 Amp, 120/240 Vac bolt-on circuit breaker from the Q Line series. This thermal-magnetic device is designed for residential and commercial applications, featuring a compact, one-inch wide per pole footprint, ideal for installation in load centers and lighting panels. The THHQB2120GFEP incorporates ABB's Quick-make / Quick-break mechanisms for rapid and reliable circuit interruption, a common trip bar for enhanced safety, and easily visible trip indication. This specific model is part of the versatile Q Line, offering 1, 2, and 3 pole configurations and supporting optional auxiliary contact and shunt trip accessories. Q Line breakers are also available for High-Intensity Discharge (HID) lighting applications. Manufactured in the USA, the THHQB2120GFEP meets UL 489 standards and is UL Listed as HACR (heating, air conditioning, and refrigeration). Its interrupting rating is 22,000 AIC, indicated by the 'HH' in the model number. This breaker is suitable for switching duty (SWD) rated for 120 Vac fluorescent lighting loads. The Q Line circuit breakers are specifically designed as bolt-on versions, intended for direct connection to the bus connections found in load centers and lighting panels, ensuring a secure and reliable electrical connection. The Quick-make / Quick-break mechanisms ensure that the breaker trips and makes contact quickly and decisively, minimizing arcing and potential damage. The common trip bars ensure that all poles of a multi-pole breaker trip simultaneously, preventing single-phased conditions. The easy-to-spot trip indication provides immediate visual confirmation when a breaker has tripped, allowing for quick identification of circuit faults. The availability of auxiliary contact and shunt trip accessories allows for integration into more complex control and monitoring systems, enabling remote signaling and tripping capabilities. The inclusion of HID application suitability highlights the breaker's robustness for demanding lighting circuits. SKU: THHQB2120GFEP.
