Inner Range 995042 PSTN (Telephone Line) Surge Diverter

The PSTN (Telephone Line) Surge Diverter is designed to connect to the phone input on Inner Range Integriti or Concept Control Modules and other modules in the Inner Range family that have a PSTN connection. It can also be used for any third-party device where surge protection of the PSTN phone line is desired.

Sources of electrical surges are numerous. The most common is a nearby lightning strike, which will affect nearby data lines through induction. Industrial transient surges are also significant because they are man-made disturbances, caused by switching large power loads such as lighting systems, the start-up of electric motors, or industrial welders.

Surge Protectors limit the transient Voltage to a level that is safe for the equipment they protect, by conducting the large surge current safely to ground.
