description

These devices are designed to limit overvoltages on the telephone line. Overvoltages are normally caused by

a.c. power system or lightning flash disturbances which are induced or conducted on to the telephone line. A

single device provides 2-point protection and is typically used for the protection of 2-wire telecommunication

equipment (e.g. between the Ring to Tip wires for telephones and modems). Combinations of devices can be

used for multi-point protection (e.g. 3-point protection between Ring, Tip and Ground).
