Tmax XT Range

ABB has expanded the range of molded case circuit breakers with the new Tmax XT. The series combines extremely high breaking capacities and excellent protective properties with extremely precise measurement and connectivity functions. The Tmax XT is suitable for demanding applications from 160 to 1,600 A. In conjunction with electronic triggers of the smallest sizes, it guarantees uninterrupted operation and protects the plant investments made. Thanks to the integrated connectivity, the status and performance data of the molded case circuit breakers are transferred to the ABB Ability Cloud platform and can be called up in real time via smartphone, tablet or PC. The intelligent overcurrent protection releases can reduce energy consumption by up to 20%. All sizes have the same logic, the same functions and the same intuitive interface, which saves considerable time during installation.

- Uniform device family from 160 to 1,600 A.
- Improved protection, measurement and connectivity functions
- High breaking capacities in demanding applications
