This part of the IEC 61643 series is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages.
These devices are intended to be connected to telecommunications and signalling networks, and equipment rated up to 1 000 V RMS and 1 500 V DC.
These telecommunications and signalling networks may also provide power on the same line, e.g Power over Ethernet (PoE).
Performance and safety requirements, tests and ratings are specified in this standard. These devices contain at least one voltage-limiting component (clamping or switching) and are intended to limit surge voltages and divert surge currents.
