Ko te AC contactor he mea hanga whakamua me te whakamahanga nui i te ao i roto i ngā rara a - huri (AC) o ngā rārangi ā - waha. Hei tūmomo whakarite pūngao tonu ia hei whakatū whakaaetanga, e whai ana i te kawe i te take ā - waha ki ngā whatunga rerekē, ko ngā motokā e utu nei, engari heoi anō hoki ki ētahi atu whenua pūngao, pēnei i ngā rārangi mārama, ngā take whakawhitiwā, me ngā putiputi mahi. Ko te whakapae mahi matua o te AC contactor kei roto i te kotahiwhā o te take pūngao. I te waehere i te take pūngao ki te kōura o te contactor, ka puta mai he take maero. Ka whakahīnaki tēnei take maero i te kōpu kīrearea, e honohono ana ki tētahi wāhi takotoranga. Ka whakapā kē ngā takotoranga, ka taea e rātau ki te noho i runga i ngā take tika (NO) rānei ko ngā take here (NC). Ki te whakatakoto i te motokā, hei tauira, ka mutu ngā take tika (NO) i te waehere i te kōura, ka whakamutu te take ā - waha, ka whakaae kē ki te kuhu mai i te take AC ki te motokā. I te whakatū i te motokā, ka taea e te contactor te whakatau ki te whakarite i te motokā, i te mutu i te waehere i te kōura, ka hinga te take maero, ka hoki ngā takotoranga ki ō rātau wāhi tuatahi, ka whakamutu te kuhu mai o te take. E rahi atu ana ngā AC contactor i ngā momo rahi me ngā tohu, e hāngai ana ki ngā hiahia taunakitanga. Ko te take kawe o te contactor he mea nui. Ko ngā contactor iti - take e pai ana ki ngā hiahia iti - take, pēnei i te whakarite i ngā motokā iti i roto i ngā whare whakaruruhau rānei ko ngā putiputi mahi iti. Ki te taha ki reira, ko ngā contactor rahi - take i hangaia hei kawe i ngā take nui i roto i ngā wāhi mahi, pēnei i ngā take i roto i ngā whare hanga, ngā take whakaputa, me ngā whare nui ā - porihanga. Ko te hanga o ngā AC contactor e mahi ana i ngā take hoki, pēnei i te whakaiti i te take whakapapa. I te whakatūpū i ngā takotoranga o te contactor, ka kitea te take whakapapa i te take nui me te take ā - waha. Ki te whakamana i te whakakore i ngā takotoranga, ka kitea te take whakapapa i te take nui me te take ā - waha. Ko ngā AC contactor e whakarite ana i ngā take whakapapa, pēnei i ngā take whakapapa, me ngā whenua kiko kia whai mana ki te take whakapapa. Ko ngā AC contactor he mea nui i roto i ngā maru whakarite motokā (MCCs), ka whakamahi hei whakarite me te tiaki i ngā motokā rerekē i roto i ngā wāhi mahi rānei ko ngā ā - porihanga. Ka whakamahi hoki i ngā ratonga whakaritenga, ka taea e rātau te whakarite i te motokā i te tūmahi rānei ko te wāhanga o te hanga. Ki te taha, ko ngā AC contactor ka whakamahi i roto i ngā ratonga whakarite mārama hei whakakuhu i ngā take mārama nui ki te tūmahi rānei ko te mutu, me ngā ratonga whakawhitiwā me ngā whakarite i te mahi o ngā pūkōkō, ngā pūtake, me ētahi atu whenua. Ko ō rātau take whakarite me ō rātau take whakarite e mahi ana i te take whakarite me te take whakarite i ngā take ā - waha.
