EVS-EN 60947-5-4:2001

Applies to separable contacts used in the utilisation area considered such as switching element for control circuits. Two rated voltages are taken into consideration: - above (and including) 10 V (typically 24 V) where contacts are used for switching loads with possible electrical erosion; - below 10 V (typically 5 V) with neglible erosion, such as electronic circuits. Does not apply to contacts used in the very low energy area of measurement, for example sensor or thermocouple systems.
