2 Pole - T1PDM1/12.5/25/230 & 230R

Type 1 - Class I / Type 2 - Class II - Single Phase - 2 Pole - 12.5kA - 25kA - 230VAC

The T1PDM1/12.5/25/230 and the T1PDM1/12.5/25/230R are two-pole, Type 1 and 2 MOV + GDT lightning arrester according to EN 61643-11 and IEC 61643-11.

These arresters are recommended for use in theLightning Protection Zones Concept at the boundaries of LPZ 0 – 1 (according to IEC 1312-1 andEN 62305) where they provide the equipotential bonding and discharge of both, the lightning current and the switching surge, which are generated in power supply systems entering the building.

The use of these arresters is mainly in the power supply lines, which are operated as TN-S and TT systems.

The main use of arrester is in structures of LPL III – IV according to EN 62305.Function of Remote Monitor Terminals (RMT)* When the T1PDM1/12.5/25/230R is operating correctly, the terminations 1-2 are connected tonormally closed contacts, 2-3 are normally open. If the internal varistor component is damaged asa result of thermal overloading, terminations 1-2 will then be open and 2-3 closed.
