An Isixhobo soqhagamshelwano lwe-ACyinxalenye yombane ene-voltage ephantsi esetyenziselwa ukudibanisa nokuqhawula iisekethe eziphambili ze-AC rhoqo kumgama omde. Isetyenziswa kakhulu kulawulo lweemoto, ukusasazwa kwamandla, ukuzisebenzela kwemizi-mveliso, kunye nokwakha iinkqubo zombane. Umsebenzi wayo ophambili kukufezekisa ulawulo lokuqala nolokumisa izixhobo zombane ngokutsala oonxibelelwano ngeekhoyili ze-electromagnetic, kwaye ikwanakho ukusetyenziswa kunye neenkqubo zokukhusela ukugqithiswa. Ii-contactor ze-AC zisetyenziswa rhoqo kwiimpompo zamanzi, iifeni, ii-air conditioner, ii-elevator, izixhobo zemveliso, iikhabhinethi zokuqalisa iimoto kunye neenkqubo zokulawula izibane, ezinokuphucula ngempumelelo umgangatho wokhuseleko kunye nokuzisebenzela we-automation wolawulo lwesekethe.

Kwiindlela ezisebenzayo, ii-contactors ze-AC zikhethwa ngokusekelwe kumlinganiselo wazo wamandla, i-voltage yekhoyili, inani leepali kunye nendawo yokusetyenziswa. Umzekelo, izixhobo ezincinci zasekhaya okanye zemizi-mveliso ezikhaphukhaphu zihlala zisebenzisa iinkcukacha ze-9A ukuya kwi-32A, ngelixa izixhobo ezinkulu zasemzimbeni zinokusebenzisa ii-contactors ezinamandla aphezulu ezinomthamo ongaphezulu kwe-65A. Iimpawu eziqhelekileyo ziquka iSchneider Electric, iSiemens, iABB kunye ne-brand yasekhaya iChint, njl.

Ngokwexabiso, ii-contactors ze-AC zahluka kakhulu ngenxa yeenkcukacha kunye neempawu: ixabiso lemarike leemveliso ezincinci ze-9A ukuya kwi-18A limalunga ne-50 ukuya kwi-150 yuan ngesiqwenga ngasinye, elo leemveliso eziphakathi ze-32A ukuya kwi-65A limalunga ne-150 ukuya kwi-500 yuan ngesiqwenga ngasinye, kwaye elo leemveliso ezinamandla aphezulu ze-100A nangaphezulu liqhele ukuba yi-500 ukuya kwi-2,000 yuan okanye ngaphezulu. Iimpawu ezingenisiweyo zihlala zibiza kakhulu kunezasekhaya, kodwa zineengenelo ezithile ngokubhekiselele kuzinzo, ubomi bokuphila kunye nokuthembeka. Ke ngoko, kwiiprojekthi zobunjineli, kufuneka kwenziwe ukhetho olufanelekileyo kunye nomthamo womthwalo, indawo yokusetyenziswa kunye nohlahlo-lwabiwo mali.
