LW28 Series Changeover Rotary Cam Switch
LW28 Series Universele switchover switch benammen brûkt foar AC 50Hz, rated spanning oant 380V en ûnder, rated stroom nei 160A elektryske sirkwy foar hânmjittich meitsjen of brekken fan it circuit foar de doelen fan kontrôle en konverzje, kin ek kontrolearjende trije-fase asynchrone motors en circuit direkt as de doelen fan master kontrôle en mjitting.De produkten in soad brûkt, ynstee fan de ferskate nasjonale switch, kin brûkt wurde as de circuit kontrôle switch, mjitapparatuer Switches, motor control switches en de master control switch, en welding machine switch ensafuorthinne.Neilibjen fan noarmen: De feroaring switch gebrûk nei de wichtichste circuit switching en direkte kontrôle foldogge oan GB14048.3-2001.
De oerstap switch gebrûk te behearskje kontrôle foldocht oan GB14048.5-2001 en IEC 60947.3.
Normale Arbeidsomstannichheden
1.De ambient lucht temperatuer net boppe +40 ℃, de gemiddelde temperatuer binnen 24 oeren en net mear as +35 ℃.
2.De ambient lucht temperatuer is net leger as -5 ℃.
3.Installaasje site hichte net mear as 2000m.
4.De relative fochtigens fan 'e loft net mear as 50% as de maksimale temperatuer +40 ℃ is en by in legere temperatuer in hegere relative fochtigens mooglik makket, lykas as temperatuer 20 ℃ is, berikke de relative fochtigens 90%.Om condensation soms fanwege temperatuer feroarings moatte nimme spesjale maatregels.
