Daim ntawv thov

LR1 seriesthermal overload relayyog tsim rau overload thiab theem tsis ua hauj lwm tiv thaiv ntawm AC motors nrog zaus ntawm 50/60Hz, voltage mus txog 690v, tam sim no mus txog 0.1-80A nyob rau hauv 8-teev lub luag hauj lwm los yog uninterrupted luag hauj lwm.

Kev ua haujlwm tau muab los ntawm cov relays, yog kev tiv thaiv theem tsis ua haujlwm, ON / OFF qhia, ntsuas kub

them nyiaj, thiab phau ntawv / tsis siv neeg rov pib dua.

Cov qauv siv tau: Lub teb chaws tus qauv: GB 14048. Cov qauv sib txawv: 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 ntau tshaj +35C hauv 24 teev.

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

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

Qhov siab tshaj qhov nruab nrab qhov av sib piv ntawm lub hli no tsis tuaj yeem tshaj 90%, Qhov hloov pauv

ntawm qhov kub thiab txias ua rau dew ntawm cov khoom yuav tsum tau txiav txim siab.

Cov pa phem: Class 3.

Txoj kab nqes ntawm qhov chaw nruab 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.
