Overview

The ABB THQL2140ST1 (SKU: THQL2140ST1) is a UL-listed, 2-pole circuit breaker featuring a shunt trip mechanism, designed for industrial and commercial applications requiring remote shutdown capabilities. This breaker provides standard thermal and magnetic tripping protection along with the added flexibility of external activation via remote switches or control systems. It is rated for 40A continuous current and operates at 120/240V AC, offering a robust interrupting rating of 10kAIC for reliable performance under fault conditions. The shunt trip function makes it ideal for emergency shutdowns, load shedding, or automated safety protocols in critical environments such as data centers, manufacturing plants, and healthcare facilities. Manufactured in the USA by ABB - Electrification, a global leader in electrical distribution, the THQL2140ST1 requires 3 pole spaces (2P+1ST) in standard panel configurations, allowing for straightforward integration into existing systems. Its compact design facilitates upgrades or replacements. Engineered for durability and compliance with the highest safety standards, this 40A breaker with 10kAIC interrupting capacity ensures dependable performance for applications where operational continuity and equipment safety are paramount.
