Overview

The ABB QB Series THHQB22060 is a 60 ampere, 2-pole bolt-on miniature circuit breaker designed for direct mounting to bus connections in load centers and lighting panels. Part of ABB’s Q-Line family, this thermal-magnetic breaker features a 1-inch per pole width, optimizing panel space while delivering reliable overcurrent and short-circuit protection for residential and commercial electrical systems. Rated for 22,000 AIC at 240Vac, it provides robust fault current interruption, ensuring system safety and compliance with branch circuit requirements. This breaker incorporates a Quick-make/Quick-break mechanism for rapid fault response, minimizing downtime and reducing the risk of equipment damage during fault conditions. The common trip bar ensures balanced protection across both poles, preventing unbalanced current flow and enhancing system reliability. An easy-to-spot trip indicator simplifies maintenance and troubleshooting, allowing technicians to quickly identify tripped circuits and restore power. It is available in 1-, 2-, and 3-pole configurations to accommodate single-phase lighting circuits, split-phase distribution, and three-phase systems. Optional accessories such as auxiliary contacts and shunt trips enable customization for specialized installations, including remote monitoring and emergency shutdown capabilities. Designed for compatibility with 120Vac, 120/240Vac, and 240Vac systems, the THHQB22060 is suitable for reverse feed applications, offering installation flexibility in both new construction and retrofit projects. Its non-interchangeable trip design prevents unauthorized adjustments, maintaining consistent protection levels. With a continuous current rating of 60A and fixed long-time and instantaneous trip functions, this breaker delivers predictable performance under normal and fault conditions. Order SKU THHQB22060 for reliable, space-efficient circuit protection in your next electrical installation.
