ATSHOCK series protectors have been tested in offi cial, independent
laboratories obtaining their characteristics according to applicable
standards (shown in the table).
ATSHOCK T25 surge protection devices are to be installed in parallel
with the low voltage supply line, connected to a phase, neutral and
The power should be disconnected during the installation of the
It can be installed in combination with ATSUB or ATCOVER. In either
case, both must be separated by at least 10 meter cable or, if this is
not possible, by a decoupling inductor ATLINK, in order to achieve a
correct coordination between them.
