ABB THHQB1120

The ABB THHQB1120 is a 20 Amp, 120/240 Volt AC, 1-pole breaker designed for reliable circuit protection. Part of the THHQB series, this miniature circuit breaker is bolt-on, meaning it mounts securely in panelboards and load centers, offering a sturdier connection compared to plug-in types. It interrupts electrical currents promptly when faults occur, helping to keep your system safe. The breaker connects directly to bus bars, which simplifies wiring by eliminating the need for pigtail connections and keeps your panelboard neat and organized. Rated with a 22 kAIC interrupting capacity, it’s UL listed for use in HVAC (heating, ventilation, and air conditioning) applications. Distributed by BSP Automation, this breaker is a solid choice for folks looking to keep their electrical setups running smoothly without any hassle.
