Type 1+2 Lightning Current and Surge Arrester (KM1+2 12.5 3+0 SC)

Product Information:

Varistor based combined Type 1+2 lightning current and surge arrester. Use in TN-C system sub-distribution boards on the boundary of LPZ0 and LPZ1 and main distribution boards on the boundary of LPZ1 and LPZ2 (if >50m away from the MDB).Suitable for houses, commercial and industrial buildings.Kingsmill fully coordinated mains devices provide complete protection from 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)

Standards: BS:EN 62305 (Lightning Protection) and EN 61643-11 (Surge Protection Devices).

LPL I + IISystem: Three Phase TN-CMDB: –SDB: Boundary of LPZ1 and LPZ2 if >50m away from MDB.

LPL III + IVSystem: Three Phase TN-C & TN-C-CMDB: Boundary of LPZ0 & LPZ1SDB: Boundary of LPZ1 & LPZ2 if >50m away from MDB.

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, signaling lines
• Coaxial lines for CCTV, TV, & antenna cables

Field based electronic equipment also need to be protected.
