    Abstract - (Show below) - (Hide below)

    Explains the principles for selection, operation, location and co-ordination of SPDs to be connected to 50 Hz to 60 Hz a.c. power circuits and equipment rated up to 1000 V r.m.s.

    Scope - (Show below) - (Hide below)

    This Technical Specification describes the principles for selection, operation, location and co-ordination of SPDs to be connected to 50 Hz to 60 Hz a.c. power circuits and equipment rated up to 1 000 V r.m.s..

    NOTE 1 This Technical Specification deals only with SPDs and not with SPDs components integrated inside equipment.

    NOTE 2 Additional requirements may be necessary for special applications such as electrical traction, etc.

    NOTE 3 It should be remembered that IEC 60364 series and EN 62305-4 are also applicable.
