Varistor based two pole Combined Type 1+2 lightning current and Surge Arrester. Use in TN-S and TN-C-S system main distribution boards on the boundary of LPZ0 and LPZ1 and sub-distribution boards on the boundary of LPZ1 and LPZ2 (if >50m away from the MDB).Suitable for houses, commercial and industrial buildings.Kingsmill’s coordinated mains devices provide complete protection from the entry point to equipment.
Benefits: No follow-through current. No leakage current. Coordinated range (install in close proximity to each other)Standards: BS:EN 62305 (Lightning Protection) and EN 61643-11 (Surge Protection Devices).
LPL I + IISystem: Single Phase TN-S &TN-C-SMDB: –SDB: Boundary of LPZ1 and LPZ2 if >50m away from MDB.

A lightning surge protection device prevents damage to electrical and electronic equipment from transient over-voltage events by blocking or redirecting surge current to the ground instead of passing through the equipment. In a well -designed system, it is important that for each building, both the incoming and outgoing circuits are protected by surge protection devices (where the cables enter and exit the building).
This includes:
Field-based electronic equipment also needs to be protected.
