3UA seriesthermal overload relayyog tsim rau kev tiv thaiv overload thiab theem-kev ua tsis tiav ntawm AC

cov cav nrog zaus ntawm 50 / 60Hz, voltage txog li 690-1000V, tam sim no txog li 0.1-630A nyob rau hauv 8-

ua haujlwm tsis tu ncua lossis ua haujlwm tsis tu ncua.

Cov haujlwm uas cov relays no muab yog kev tiv thaiv theem tsis ua haujlwm, kev them nyiaj kub, qhia ON/OFF thiab pib dua tes/tsis siv neeg.

Cov Qauv Siv Tau: Lub Tebchaws Tus Qauv: GB 14048, Tus Qauv Thoob Ntiaj Teb: IEC 60947-4-1.

Cov relays tuaj yeem raug ntsia rau ntawm cov contactors lossis ntsia ua ib chav.

Cov xwm txheej ua haujlwm

Qhov siab tsis tuaj yeem tshaj 2000m.

Qhov kub thiab txias: -5 "C ~ + 55C thiab qhov kub nruab nrab tsis pub tshaj + 35C hauv 24 teev.

Huab cua: Cov av noo sib piv tsis pub tshaj 50% ntawm qhov siab tshaj plaws +40 C, thiab nws yuav siab dua ntawm a

qhov kub qis dua. Qhov kub nruab nrab qis tshaj plaws tsis pub tshaj +20C hauv lub hli ntub tshaj plaws.

Qhov nruab nrab ntawm cov av noo ntawm lub hlis no yuav tsum tsis pub tshaj 90%, Yuav tsum xav txog qhov kev hloov pauv ntawm qhov kub thiab txias ua rau cov dej noo ntawm cov khoom.

Chav kawm ntawm kev ua qias tuaj: Chav kawm 3.

Qhov nqes hav ntawm qhov chaw teeb tsa thiab qhov chaw ntsug tsis tuaj yeem tshaj ± 5 °

Khaws cia kom deb ntawm cov khoom tawg, corrosive thiab hluav taws xob atomy.

Khaws kom qhuav.

Cov khoom yuav tsum tau siv thiab ntsia rau ntawm qee qhov chaw yam tsis muaj kev poob siab, kev co thiab lwm yam.
