AT82 Series – ATSUB-D M 3/4DIN
Compact Single-phase protector for household environment
Efficient protection against transient overvoltages for single-phase
power supply lines with neutral type TT, using a metal oxide varistors
and gas discharge tubes. Medium protection according to coordinated
stages protection recommended in Regulation of Low Voltages (RBT
ITC23). Specially prepared to be installed in houses according to ITC25 from REBT.
Tested and certified as Type 2 and 3 according to regulations EN
61643-11 and GUIDE-BT-23 from REBT. Suitable for Categories I, II,
III and IV equipment according to ITC-BT-23 from REBT.

Coordinable with other SPDs such as ATSHOCK, ATSHIELD and
ATCOVER series.

Made up of zinc oxide varistors and gas discharge tubes able to
ATSUB-D M 3/4 DIN
withstand very high currents.
AT-8219 ATSUB-D M 3/4 DIN

Removable cartridge than can be change in case of failure
without cable disconnection.

Thermodynamic control device, mechanical warning and remote
alarm. Red light in case of cartridge failure.
AT82 Series SPDs have been tested in official and independent
laboratories, obtaining their characteristics according to relevant
standards (shown in the table).
INSTALLATION
Install in parallel with the Low Voltage supply line, connected
to line, neutral and to ground.
When they are installed as middle protection, they must be
separated from the other protections 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.
Their installation is recommended for the houses main
switchboard according to the article 16.3 from REBT.
.
Earth connection is a must. Earthing in all the
installation must be bonded either directly or by a spark gap
and resistance should be lower than 10Ω. If the indications
of this datasheet are not fulfilled during the use or
installation of the SPDs, the protection assured by this
device could be endangered.
