Product Information:

Compact Type 3 Surge Arrester for final circuit protection. Install close to low voltage equipment for additional protection. Use with single-phase power supply systems.

Provides audible fault indication.

Features:

  • Compact design
  • Fits in a wall socket
  • Simple installation
  • Audible fault indication
  • Equipment protection up to 5m from device on connected circuit
  • Suitable up to 16A circuits

Benefits: Can be fitted in ducts, trunking, or flush type wiring boxes. Provides “fine” protection to individual sockets or circuits

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

LPL I + II and LPL III + IV
System: Single Phase TN-C, TN-S, TN-C-S and TT
Location: Boundary of LPZ2 and LPZ3 (if the electronic equipment is >5m away from SDB)

More Information:

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 needs to be protected.
