Overview

The ABB THQB2120HID is a 2-pole, 20A thermal-magnetic circuit breaker from the Q Line series, specifically designed for bolt-on mounting onto the bus connections of load centers and lighting panels. This compact breaker occupies a single inch of width per pole, making it an efficient choice for space-constrained electrical panels. Engineered for High-Intensity Discharge (HID) applications, the THQB2120HID provides reliable overcurrent protection with a 10,000 AIC (Ampere Interrupting Capacity) rating, suitable for 120/240 Vac systems. It features ABB's Quick-make / Quick-break mechanisms for rapid fault response and a common trip bar to ensure simultaneous disconnection of all poles, preventing unbalanced loads. The breaker includes an easy-to-spot trip indicator for quick fault identification and maintenance. It is UL 489 and cUL listed, meeting stringent safety standards for residential and commercial electrical systems. The THQB2120HID is part of ABB’s Q Line series, known for its versatility and compatibility with auxiliary contact and shunt trip accessories, allowing for customization to meet specific application needs. The bolt-on design ensures secure and stable connections to bus bars, enhancing system reliability. Key applications include lighting systems, particularly HID lighting, where precise overcurrent protection is critical. The breaker’s thermal-magnetic tripping mechanism responds to both overloads and short circuits, safeguarding circuits from damage. With a 20A rating, it is optimized for systems requiring stable current flow and rapid fault interruption. Manufacturer: ABB - Electrification. SKU: THQB2120HID. Country of Origin: US.
