ABB SACE Tmax XT / Emax 2 Automatic Transfer Switch ATS Series

The ATS (Automatic Transfer Switch) is a network-unit transfer device used in installations where switching from the main power line to an emergency line is required in order to ensure that power is supplied to the loads in the case of power loss or abnormalities from the main line.
These devices are able to control the entire transfer procedure automatically, but also offer commands for performing the procedure manually.
The new generation of ATSs (ATS021 and ATS022) offers the most advanced and complete solution for ensuring service continuity.
The ATS021 and ATS022 devices can also be used with all automatic circuit-breakers and switch-disconnectors of the Tmax XT family.
The ATS021 and ATS022 devices have been designed to be self-powered.
