IEC 60947-5-4:2002
IEC 60947-5-4:2002 applies to separable contacts used in the utilization area considered, such as switching elements for control circuits. This standard takes into consideration two rated voltage areas: a) above (and including) 10 V (typically 24 V) where contacts are used for switching loads with possible electrical erosion, such as programmable controller inputs; b) below 10 V (typically 5 V) with negligible electrical erosion, such as electronic circuits. This second edition cancels and replaces the first edition which was issued as a technical report in 1996. It now has the status of an International Standard.
