Molded case circuit breakers for system protection in accordance with EN 60947-2 (DIN0660, Part 101), molded case load disconnectors in accordance with EN 60947-3 (DIN0660, Part 107). The Tmax XT molded case/load disconnectors meet the different system requirements of direct and alternating current networks. Tmax XT with thermomagnetic or electronic releases can be used to protect power distribution systems, cables, generators and motors. Many of these circuit breakers can also be used in communication systems. Extensive connection conversion kits, mechanical and electrical accessories as well as version conversion kits (plug-in / withdrawable) are available. Various fieldbus and IP communication protocols can be used. The installation process is simplified thanks to Bluetooth and Ekip connectivity for mobile devices. The connectivity integrated into the SACE Tmax XT series links smartphones, tablets and PCs in real time with data analysis tools on the ABB AbilityTM Cloud platform.
