Ole vacuum circuit-breakers fa'asologa o Saina VD4 o masini ia mo le fa'apipi'iina o mea e sui ai totonu.Fa'amolemole fa'afeso'ota'i ROCKWILL mo mana'oga fa'apipi'i fa'apitoa.VD4-R fa'asologa va'a vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum vacuum fatafa'i fa'ata'ita'i mo fa'apipi'i totonu fa'aalia le auala fau fau pou.O pou ta'itasi o lo'o i ai se vacuum interrupter o lo'o tu'uina i totonu o le resini pe a fa'apipi'i le pa'u fa'afetai i se faiga fa'apitoa o le gaosiga.O lenei faiga faufale e puipuia ai le vacuum interrupter mai te'i, filogia ma condensation.
O le masini fa'aogaina o le ituaiga malosi e teuina e aunoa ma se malaga e tatala ma tapuni tuto'atasi tusa lava po'o le a le gaioiga a le tagata fa'afoe.O le faʻaogaina o masini e faʻaaogaina lautele i VD4-R faʻasologa vaʻavaʻavaʻavaʻa faʻatasi ma le pule i luma.
E mafai ona fa'amamao le va'ava'ava'a pe a fa'apipi'i i mea fa'a-eletise fa'apitoa (gearmotor, tatala ma tapuni tatala).
O le faʻaogaina o le masini, o pou e tolu ma masini o loʻo iai nei (pe a tuʻuina atu) o loʻo faʻapipiʻiina i luga o se faʻavaa uʻamea e aunoa ma ni uili.O le faufale e fa'apitoa, malosi ma fa'atapula'aina le mamafa.
VD4-R fa'asologa va'ava'ava'a va'ava'ai fa'atasi ai ma fa'agaioiga fa'agaoioiga pito i tua o masini fa'amau fa'amaufa'ailoga mo le olaga atoa. (Tulaga IEC 62271-100)
