Low-voltage switchgear and controlgear - Part 5-4: Control circuit devices and switching elements - Method of assessing the performance of low-energy contacts - Special tests

DS/EN 60947-5-4-2004 发布历史

This part of IEC 60947 applies to separable contacts used in the utilisation area considered, such as switching elements for control circuits. This standard takes into consideration two rated voltage areas: - above (and including) 10 V (typically 24 V) where contacts are used for switching loads with possible electrical erosion, such as programmable controller inputs; - below 10 V (typically 5 V) with neglible electrical erosion, such as electronic circuits. This standard does not apply to contacts used in the very low energy area of measurement, for example sensor or thermocouple systems. The object is to propose a method of assessing the performances of l
