RMNF22TB30 3-waahanga mana relay, Harmony Mana Relays 8A 2CO overrequency and underfrequency 208-480V AC

No te awhe relay mana whakahaere 3-waahanga tenei a Schneider Electric Harmony Control. Ko tenei rei whakahaere 3-waahanga kua whakauruhia ki te hangarau NFC e kawe mai ana i te mahi matihiko hei utu mo te mahi tairitenga. He 8A multifunction 3-phase mana relay tenei e aro turuki ana i nga wahanga-3, 3-waahanga ranei me te whatunga Neutral me te wa roa e taea te whakarite mai i te 0.1s ki te 60min. Ma te Harmony NFC App, ka taea te whakakotahi i nga momo whakaoho ma te whakamahi i te AND, OR me te NOT arorau hei hanga i nga huinga aroturuki ahurei mo nga putanga rei e rua ka taea te whirihora takitahi. NFC 3-waahanga mana relay he tohutoro kotahi e tautoko ana i nga mahi e 7 ara ko te mate Wāhanga, te raupapa Wāhanga, Asymmetry, Undervoltage, Overvoltage, Under-frequency, and Over-frequency. Ko te relay mana 3-waahanga he IP20 (whakapae), IP40 (whare), me te IP40(paepae o mua) kua tiakina. I tua atu, ko te kupuhipa 4 mati ka whakarei ake i te haumarutanga ma te aukati i nga whakarereketanga kore mana.
