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

ʻO kēia 3-phase control relay no ka Schneider Electric Harmony Control relays. Hoʻohui ʻia kēia relay mana 3-phase me ka ʻenehana NFC e lawe mai i ka hana kikohoʻe ma mua o ka hana analog. ʻO kēia kahi 8A multifunction 3-phase control relay e nānā ana i ka 3-phase a i ʻole 3-phase me ka pūnaewele Neutral a loaʻa iā ia ka manawa lohi o 0.1s a 60min. Me ka Harmony NFC App, hiki ke hoʻohui ʻia nā ʻōhua ʻokoʻa me ka hoʻohana ʻana i ka AND, OR a me ka NOT logic e hana i nā hui nānā kūʻokoʻa no nā hoʻopuka relay ʻelua i hiki ke hoʻonohonoho ʻia. ʻO ka NFC 3-phase control relay he kuhikuhi hoʻokahi e kākoʻo ana i nā hana 7 ʻo ia ka Phase loss, Phase sequence, Asymmetry, Undervoltage, Overvoltage, Under-frequency, a me Over-frequency. ʻO ka 3-phase control relay he IP20 (mau pahu), IP40 (hale), a me IP40 (pane mua). Eia kekahi, hoʻonui ka ʻōlelo huna 4 i ka palekana ma ka pale ʻana i ka hoʻololi ʻole ʻia o nā hoʻonohonoho.
