Overview

The ABB Electrification THQB3440 is a 1-inch module, bolt-on industrial circuit breaker designed for reliable power distribution in load centers and lighting panels. Rated at 40 Amperes with a 240 Vac operating voltage, this Type THQB breaker delivers 10,000 AIC (Ampere Interrupting Capacity) for robust fault protection. The THQB3440 features a Quick-make / Quick-break mechanism, ensuring rapid response during overcurrent events while maintaining operational safety. Common trip bars provide simultaneous disconnection across poles, preventing unbalanced loads and enhancing system reliability. An easy-to-spot trip indication allows for quick visual confirmation of fault conditions, reducing downtime during maintenance. This breaker is part of ABB’s Q Line series, a line of compact, thermal-magnetic devices engineered for residential, commercial, and light industrial applications. Compatible with standard 1-inch per pole mounting configurations, the THQB3440 integrates seamlessly into existing electrical panels. Manufactured in the US, this model is built to meet the demands of industrial environments where dependable circuit protection is critical. The bolt-on design simplifies installation and replacement, making it a practical choice for panel upgrades and new installations alike.
