3 UA seriesthermal overload relayyog tsim rau overload thiab theem tsis ua hauj lwm tiv thaiv AC

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

xuab moos ua haujlwm lossis tsis muaj kev cuam tshuam.

Cov haujlwm muab los ntawm cov relays no, yog kev tiv thaiv theem tsis ua haujlwm, kev them nyiaj kub, ON / OFF qhia thiab phau ntawv / tsis siv neeg rov pib dua.

Cov qauv siv tau: Lub teb chaws tus qauv: GB 14048, Intermational Standard: IEC 60947-4-1.

Cov relays tuaj yeem ntsia tau rau hauv contactors lossis ntsia raws li ib chav.

Cov xwm txheej ua haujlwm

Qhov siab siab tsis tuaj yeem tshaj 2000m.

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

Atmosphere: Sib piv cov av noo tsis tshaj 50% ntawm max +40 C, thiab nws yuav siab dua ntawm a

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

Qhov siab tshaj plaws nruab nrab qhov sib piv cov av ntawm lub hli no tsis tuaj yeem tshaj 90%, Qhov kev hloov ntawm qhov kub thiab txias ua rau cov dej dew ntawm cov khoom yuav tsum tau txiav txim siab.

Cov pa phem: Class 3.

Txoj kab nqes ntawm qhov chaw nruab nrab thiab ntsug saum npoo tsis tuaj yeem tshaj ± 5 °

Ua kom deb ntawm tawg, corrosive thiab hluav taws xob atomy.

Ua kom qhuav.

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