ATCOMPACT T1 50kA- Protection for three phase lines with ATSHOCK 50kA

ATCOMPACT protection boxes are made of several kind of SPD aiming the protection of all lines out from single phase SPD, including the protective fuses against short circuits.

ATCOMPACT Surge Protective Devices are to be installed in parallel with the supply line, without altering at all its way of working under normal conditions. Combinations can be made for protection either in common mode (ground referred) or differential (between line/s and neutral).

Compact box easy to install and with the same advantages as Aplicaciones Tecnologicas SPDs give: robust, quick, reliable and tested according current standards (EN 61643-11) in Official independent laboratories.

Installation ATCOMPACT

ATCOMPACT T1 50kA - Bộ cắt sét nguồn điện 3P-50kA

ATCOMPACT boxes are to be installed in parallel with the Low Voltage supply line, connected to line, neutral and ground. Fuses or circuit breakers must be present upstream. They will be disconnected during the installation for working security. When this ATCOMPACT is installed as middle protection, other protectors must be separated by at least 10 meter cable or, it this is not possible. by decoupling inductors ATLINK, in order to achieve a correct coordination between them.

General nomenclature
- T1 : Three-phase protection type 2
- 50kA: Max. discharge current for single phase

Earthing connection

Earthing in all the installation must be bonded either directly or by a spark gap and resistance should be lower than 10 Ω. 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.
