Varistor based three-pole Type 2 Surge arrester. Use in TN-C system sub-distribution boards on the boundary of LPZ1 and LPZ2 (if >10m away from the MDB).Suitable for houses, commercial, and industrial buildings.Kingsmill fully coordinated mains devices to provide complete protection from 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: Three Phase TN-CSDB: Boundary of LPZ1 and LPZ2 if >10m away from MDB.
LPL III + IVSystem: Three Phase TN-CSDB: Boundary of LPZ1 & LPZ2 if >10m 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 need to be protected.
