Reaffirmed December 2010. This guide provides assistance in selecting the most appropriate type of surge protector for a particular data, communication, and/or signaling circuit application. The purpose of this guide is to enable an understanding and an evaluation of the functions of the various typ...

This standard applies to surge protectors for application on multiconductor balanced or unbalanced data, communications, and signaling circuits with voltages equal to or less than 1000 V rms, or 1200 V dc. These surge protectors are designed to limit voltage surges, current surges, or both.This stan...

This guide describes the waveform of currents likely to exist on DC feeds to equipment located at the tops of towers due to a lightning strike, and the consequences of that waveform for protector design.

An introduction to a series of guides on the application of surge protectors and protective circuits used in information and communications technology circuits, including Smart Grid data networks, is provided in this guide.
