Overview

The ABB MTK series is part of ABB’s System pro M compact family of miniature circuit breakers (MCBs). These breakers are engineered to protect electrical circuits against overloads and short circuits, ensuring safety and reliability in low-voltage installations. Moreover, their modular DIN-rail design allows quick installation, flexible configuration, and easy maintenance. In addition, ABB MTK breakers comply with IEC/EN 60898‑1 and IEC/EN 60947‑2 standards, making them suitable for both residential and industrial applications.

The MTK series is valued for its high breaking capacity, compact footprint, and long service life, reflecting ABB’s expertise in electrical protection technology.
