Technical Specification
29.130.20 Low voltage switchgear and controlgear
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.
