Cov kev ntsuas siab tshaj plaws ua haujlwm ntawm AC contactors yog 220V, 380V, 660V thiab 1140V.
Feem ntau, qhov siab tshaj plaws ua haujlwm voltage yog qhov ntsuas hluav taws xob hluav taws xob, thiab qhov kev tshem tawm hluav taws xob thiab kev nkag mus deb ntawm cov khoom siv hluav taws xob tau txiav txim siab raws li. Tus contactor feem ntau qhia txog ntau qhov kev ua haujlwm voltages, thiab tseem teev cov kev ntsuas ua haujlwm tam sim no (lossis tswj lub zog). Thaum lub ntsuas hluav taws xob ua haujlwm yog 380V, qhov ntsuas kev ua haujlwm tam sim no tuaj yeem kwv yees kwv yees sib npaug li ob npaug ntawm cov ntsuas hluav taws xob (KW).
Raws li kuv lub teb chaws tus qauv, qhov ntsuas hluav taws xob yuav tsum raug xaiv los ntawm cov txheej txheem hauv qab no:
DC: 12, 24, 36, 48, 60, 72, 110, 125, 220, 250, 440V;
AC: 24, 36, 42, 48, 127, 220, 380, 660, 1140V.
Qhov ntsuas voltage ntawm AC contactor yog dab tsi?
