Ta del standarda IEC 60947 velja za opremo za samodejno predajanje stikanja (TSE), ki je namenjena uporabi v napajalnih sistemih s prekinitvijo napajanja zaradi obremenitve med prenosom, katerih nazivna napetost ne presega 1000 V izmenične napetosti ali 1500 V enosmerne napetosti. Zajema: - ročno upravljano opremo za samodejno predajanje stikanja (MTSE); - daljinsko upravljano opremo za samodejno predajanje stikanja (RTSE); - avtomatsko opremo za samodejno predajanje stikanja (ATSE). Zajema samodejno opremo za predajanje stikanja z ohišjem ali brez. Naprave, ki so potrebne za krmiljenje (npr. krmilna stikala, itd.) in zaščito (npr. odklopniki, itd.) opreme za samodejno predajanje stikanja zajemajo ustrezni standardi IEC. Namen tega dela standarda IEC 60947 je, da navede: 1) Značilnosti opreme: a) določene vrste opreme; b) opreme, katere glavni del so naprave, ki jih zajemajo drugi standardi za proizvode IEC 60947. 2) Pogoje opreme glede na: a) dejavnost, za katero je oprema namenjena; b) delovanje in vedenje v primeru navedenih izrednih razmer, na primer kratkega stika; c) dielektrične lastnosti. 3) Preskuse, katerih cilj je potrditi, da oprema izpolnjuje te pogoje, in metode izvajanja teh preskusov. 4) Podatke, ki morajo biti navedeni na opremi in ki jih mora zagotoviti proizvajalec.
