RMNF22TB30 3-phase control relay, Harmony Control Relays 8A 2CO overfrequency and underfrequency 208-480V AC

3-phase control relay iyi ndi ya Schneider Electric Harmony Control relays range. 3-phase control relay iyi ikuphatikizidwa ndiukadaulo wa NFC womwe umabweretsa ntchito ya digito m'malo mwa analogi. Ichi ndi 8A multifunction 3-phase control relay yomwe imayang'anira 3-phase kapena 3-gawo ndi Neutral network ndipo imakhala ndi nthawi yosinthika ya 0.1s mpaka 60min. Ndi Harmony NFC App, ma alarm osiyanasiyana amatha kuphatikizidwa pogwiritsa ntchito NDI, KAPENA komanso OSATI malingaliro kuti apange kuphatikiza kwapadera kowunikira pazotulutsa ziwiri zomwe zimatha kusinthidwa payekhapayekha. NFC 3-phase control relay ndi katchulidwe kamodzi kothandizira ntchito 7 zomwe ndi gawo lotayika, gawo lotsatizana, Asymmetry, Undervoltage, Overvoltage, Under-frequency, ndi Over-frequency. Gawo la 3-phase control relay ndi IP20 (terminals), IP40 (nyumba), ndi IP40 (patsogolo) yotetezedwa. Kuphatikiza apo, mawu achinsinsi a manambala 4 amathandizira chitetezo popewa kusintha kosaloledwa kwa zosintha.
