Overview

The ABB Electrification THQB32070ST1 is a robust 2-pole, 70 Amp, 240 Vac Q Line bolt-on circuit breaker engineered for reliable thermal-magnetic protection in residential and commercial electrical systems. This compact device features a one-inch width per pole, optimizing space within load centers and lighting panels. Designed for direct bolt-on connection to bus connections, the QB series ensures secure and stable installation, crucial for system integrity. Safety and reliability are paramount, with the inclusion of Quick-make / Quick-break mechanisms for rapid and decisive circuit interruption, minimizing arc flash duration and safeguarding equipment. Common trip bars are integrated to guarantee simultaneous tripping of all poles, effectively preventing single-phased conditions and enhancing overall system safety. An easy-to-spot trip indication provides clear visual confirmation of a tripped breaker, simplifying troubleshooting and reducing potential downtime. This breaker offers a 10,000 AIC (Amperes Interrupting Capacity) and is suitable for HID (High-Intensity Discharge) applications. Auxiliary contact and shunt trip accessories can be specified for customized functionality. The THQB32070ST1 is built, tested, and listed to UL and cUL standards (UL 489). It is also UL Listed as HACR (heating, air conditioning, and refrigeration). SKU: THQB32070ST1. Country of Origin: US. UNSPSC Code: 39121603.
