Type 3 Surge Arrester (KM3 10 1+1 SC)

Product Information:

Combination of varistor SPD and encapsulated spark gap connected in the 1 + 1 mode. Use in TN-C, TN-S, TN-C-S, and TT systems on the boundary of LPZ2 and LPZ3. Locate as close as possible to the equipment to be protected.Suitable for houses, commercial and industrial buildings.Kingsmill fully coordinated mains devices to 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 + II and LPL III + IVSystem: Single Phase TN-C, TN-S, TN-C-S and TTLocation: Boundary of LPZ2 and LPZ3 (if the electronic equipment is >5m away from SDB)

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.
