Description

Three Phase T2/3 Surge arrester

Designed for installation at the boundary of LPZ 1 -2 or higher, to protect low voltage equipment from surge damage. Designed according to IEC 61643-11, this device is a pluggable, modular, Class II SPD for TT, TN-S and TN-C-S power supply system. This surge protective device is usually installed in a distribution board or other control panel, protecting devices or equipment downstream.

Type 2 - Class II - Three Phase - 4 Pole - 20kA - 50kA - 275VAC

The T2PDM3/20/50/275 & T2PDM3/20/50/275R (Remote Version) are four pole,metal oxide varistor surge arrester combined with gas discharge tube,Type 2 according to EN 61643-11 and IEC 61643-11.

These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 1-2 (according to IEC 1312-1 and EN 62305), where they provide the equipotential bonding and discharge of the switching overvoltage, which is generated in power supply systems entering the building.

The main uses of these arresters is in all kinds of industry, residential and administration buildings.

They are to be placed into the subsidiary switchboards or control boxes.

These units have removable and replaceable modules.
