  • 13 very important type tests of a low voltage switchgear

    Type Tests Defined in IEC 61439Type TestsAdditional Type TestsCertification of distribution assemblies is defined by international standard IEC 61439-1. This standard provides common rules that are recognized worldwide. Compliance with the standard is certified, depending on the country or market, by a declaration of the panel builder, the design office, the installer or the user. Just to mention before going into test, that low voltage switchgear and controlgear assemblies (Un ≤ 1000 V AC) may be used at the origin of an electrical installation with: 1. Low Voltage Main switchboard (transformer area) 2. Low Voltage Main Distribution Board (technical area) and 3. Sub Distribution boards Seven type tests are carried out officially on low voltage assemblies representative of the usual wiring configurations and equipment layouts. These assemblies are called ‘standard assemblies’. By definition, standard assemblies only contain layouts that have undergone type tests.
