Low-voltage switchgear and controlgear - Part 5: Control circuit devices and switching elements - Section 4: Method of assessing the performance of low energy contacts. Special tests
OVERVIEW
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, such as programmable controller inputs, and below 10 V (typically 5 V) with neglible erosion, such as electronic circuits. It is a proposed method of assessing the performances of low energy contacts giving: useful definitions; general principles of test methods which are to monitor and record the behaviour of contacts at each operation; functional bases for the definition of a general testing equipment; preferred test values; particular conditions for testing contacts intended for specific applications (such as switching of PC inputs); information to be given in the test reports; interpretation and presentation of the test results.
