Low-voltage switchgear and controlgear - Control circuit devices and switching elements. Method of assessing the performance of low-energy contacts. Special tests1 Scope and object This part of IEC 60947 applies to separable contacts used in the utilization area considered, such as switching elements for control circuits. This standard takes into consideration two typical 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
