RDA1 series pushbutton switch, rated insulation voltage 690V, siv tau rau telecontrolling electromagnetic starter, contact, relay thiab lwm yam circuit ntawm AC50Hz lossis 60Hz, AC voltage 380V thiab qis dua, DC voltage 220V thiab qis dua. Thiab lub teeb pushbutton kuj siv tau ua ib qho cim qhia. Cov khoom no ua raws li tus qauv ntawm GB14048.5, IEC60947–5-1.
Kev ua haujlwm ib txwm muaj thiab kev teeb tsa:
1 Qhov siab: qis dua 2000m.
2 Qhov kub thiab txias: tsis pub siab tshaj + 40oC, thiab tsis pub qis dua -5oC, thiab qhov nruab nrab ntawm hnub yuav tsum tsis pub ntau tshaj + 35ºC.
3 Av noo: Cov av noo sib piv yuav tsum tsis pub tshaj 50% ntawm qhov kub siab tshaj 40ºC, thiab cov av noo siab dua tuaj yeem lees txais ntawm qhov kub qis dua.
Yuav tsum tau ceev faj txog qhov condensation uas tshwm sim los ntawm kev hloov pauv kub.
4 Chav kawm ua qias tuaj: III hom
5 Qib kev teeb tsa: II hom
6 Qhov chaw teeb tsa yuav tsum tsis muaj roj xeb thiab hmoov av tsis sib txuas.
7 Lub pob nias yuav tsum tau muab tso rau ntawm lub qhov puag ncig ntawm lub phaj tswj. Lub qhov puag ncig tuaj yeem muaj qhov tseem ceeb plaub fab uas muaj qhov chaw siab dua. Lub phaj tswj tuab yog 1 txog 6 hli. Yog tias tsim nyog, siv tau gasket.
