An AC contactorchinhu chemagetsi chine voltage shoma chinoshandiswa kubatanidza nekubvisa ma AC main circuits nguva nenguva munzvimbo refu. Chinoshandiswa zvakanyanya mukudzora mota, kugovera simba, otomatiki yemaindasitiri, uye kuvaka masisitimu emagetsi. Basa rayo guru nderekudzora nekumisa michina yemagetsi nekukwevera ma contacts kuburikidza nema electromagnetic coils, uye ine kugona kushandiswa pamwe chete nemasisitimu ekudzivirira overload. Ac contactors dzinowanzo shandiswa mumapombi emvura, mafeni, ma air conditioner, ma elevator, michina yekugadzira, makabati ekutanga mota uye masisitimu ekudzora mwenje, izvo zvinogona kusimudzira zvakanyanya kuchengetedzeka uye otomatiki nhanho yekudzora circuit.

Mukushandiswa kwazvinoitwa, macontactor eAC anosarudzwa zvichienderana nemagetsi azvo, voltage ye coil, huwandu hwemapango uye nzvimbo yekushandisa. Semuenzaniso, michina midiki yemumba kana yemumaindasitiri inowanzo tora zvirevo zve 9A kusvika 32A, nepo michina mikuru yemufekitori inogona kushandisa macontactor ane simba guru ane simba rinodarika 65A. Mhando dzakajairika dzinosanganisira Schneider Electric, Siemens, ABB uye brand yemuno yeChint, nezvimwewo.

Panyaya yemutengo, macontactor eAC anosiyana zvakanyanya nekuda kwezvakagadzirwa uye mabrandi: mutengo wemusika wezvigadzirwa zvidiki zve9A kusvika 18A ungangove 50 kusvika 150 yuan pachidimbu chimwe nechimwe, wepakati nepakati wezvigadzirwa zve32A kusvika 65A ungangove 150 kusvika 500 yuan pachidimbu chimwe nechimwe, uye wezvigadzirwa zvine simba guru zve100A zvichikwira kazhinji ungangove 500 kusvika 2,000 yuan kana kutopfuura. Mabrandi anotengwa kunze kwenyika anowanzo kudhura kupfuura emuno, asi ane zvakanakira zvakasiyana maererano nekugadzikana, hupenyu uye kuvimbika. Saka, mumapurojekiti einjiniya, kusarudzwa kwakaringana kunofanirwa kuitwa pamwe chete nekukwanisa kurema, nzvimbo yekushandisa uye bhajeti.
