High-performance four-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 >100m 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.
- Remote signaling
- Reversible installation
- Biconnect terminals
- Locking pluggable modules
- Optical lifetime status indication
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 + II
System: Three Phase TN-S
MDB: Boundary of LPZ0 and LPZ1
SDB: 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).
- Mains power supplies – including UPS
- Telephone lines
- Data communication lines
- Instrumentation, control, signaling lines
- Coaxial lines for CCTV, TV, & antenna cables
Field based electronic equipment also need to be protected.
