Spare Module L-N (L-PE) | KM1+2-25 |
Heavy-duty Varistor and spark gap based Type 1+2 combined lightning current and Surge Arrester. Use in TT system main distribution boards on the boundary of LPZ0 and LPZ1.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-CMDB: Boundary of LPZ0 and LPZ1SDB: Boundary of LPZ1 and LPZ2 if >100m 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.
