Product Information:
Varistor based single pole Combined Type 1+2 Lightning Current and Surge Arrester. Use in TN-C 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.
Features:
- Remote signalling
- 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)

More Information:
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:
- Mains power supplies – including UPS
- Telephone lines
- Data communication lines
- Instrumentation, control, signalling lines
- Coaxial lines for CCTV, TV, & antenna cables
Field based electronic equipment also need to be protected.
