WSP-T1PDM3/12.5/50/230R

The WSP-T1PDM3/12.5/50/230R is a Type 1 and 2 lightning arrester according to BS EN 61643-11. These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0-1 (according to IEC 1312-1 and BS EN 62305) for lightning current equipotential bonding and elimination of switching surges that originate in power supply system’s entering the building. The main use of these arresters is structures of LPL III to IV according to BS EN 62305.

The WSP-T1PDM3/12.5/50/230R is mainly intended for use in TNS, TNC-S or TT systems.

When the WSP-T1PDM3/12.5/50/230R is operating correctly, the terminations 1-2 are connected to normally closed contacts, 2-3 are normally open. If the internal varistor component is damaged as a result of thermal overloading, terminations 1-2 will then be open and 2-3 closed.
