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.
