    内部链接及接线端子标志Intestinal conjunction & joint sign

    VLC1(16) -25、32、43接触器的电路链接及接线端子的标志见图匀。其接触系统由上、下两层八个触头组成三极主电路,每极主电路中都有一个触头是提前接通的,每路电阻切合电路由提前接通的触头与两只电阻构成。辅助触头的功能组合,由用户在订货时选定。
    VLC1(16)-63接触器的电路连接及接线端子见图2b。接触器为积木式,电阻切合电路部分在主电路部分的上方。
    The clrcuit connection and feeler sign of
    VLC1(16) -25、32、43 contactor refers to chart NO.2a.The contactor feeler systemis divided into three pole main circuit, which is made up to eight feelers with two layeers. There is a pre-connected feeler in everypole main circuit.Every resistance switching circuit is made up of the pre-connected feeler and two resistances. The assistant feelerfunction combination is up to customers´:s electric on order. The circuit connection and feeler sign of
    VLC1 (16)-63 contactorrefers to chart NO.2b, contactor for building block, the parts of resistance appropriated to circuit up the main circuit。
