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.
