External Automatic Transfer Switches ATS
The ATS (Automatic Transfer Switch) is a net-
work-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 trans-
fer procedure automatically, but also offer com-
mands 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 auto-
matic circuit-breakers and switch-disconnectors
of the Tmax XT family. The ATS021 and ATS022 de-
vices have been designed to be self-powered.
