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
| 분야 | TC 121/SC 121A : Low-voltage switchgear and controlgear |
|---|---|
| 적용범위 | 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. |
