Overview

The ABB THQB22045 is a 2-pole, 45 Amp bolt-on circuit breaker from the ABB Q Line series, designed for reliable electrical protection in residential and commercial load centers and lighting panels. This compact, thermal-magnetic device features a one-inch width per pole, optimizing space within panelboards. Manufactured by ABB Electrification, the THQB22045 is a bolt-on version of the established Q Line, specifically engineered for secure attachment to bus connections. Its robust construction and thermal-magnetic tripping mechanism provide dependable protection against overloads and short circuits. The breaker operates at a voltage of 240 Vac and offers a 10,000 AIC (Ampere Interrupting Capacity), making it suitable for standard applications. Key safety and reliability features include Quick-make / Quick-break mechanisms, which minimize arcing and contact wear for extended operational life. A common trip bar ensures that all poles trip simultaneously in the event of a fault, preventing phase imbalances. The easily visible trip indication allows for quick identification of a tripped breaker, facilitating faster system restoration and troubleshooting. This model is manufactured in the USA. The UNSPSC code for this product is 39121603. The THQB22045 is part of a broader Q Line series available in 1, 2, and 3 pole configurations, with options for auxiliary contact and shunt trip accessories, and suitability for HID applications.
