        產(chǎn)品介紹

        1 范圍:
        配DZ47分勵脫扣器 MX+OF,主要適用于交流50HZ(或60HZ),額定電壓至400V的線路中與DZ47小型斷路器或多極斷路器配裝做遠(yuǎn)距離操作,指示斷路器通斷狀態(tài)。
        2 正常工作條件和安裝條件:
        周圍空氣溫度為:-5℃~+40℃,24小時內(nèi)其平均值不超過+35℃。
        海拔高度:不超過2000M。
        大氣條件:安裝地點(diǎn)的空氣相對濕度在最高溫度為+40℃時不超過50%;
        在較低的溫度下可允許有較高相對濕度,最濕月的月平均最低溫度不超過+25℃,該月的月平均最大相對濕度不超過90%,并考慮到因溫度變化發(fā)生在產(chǎn)品表面上的凝露。
        污染等級:為污染等級2。
        安裝類別:為安裝類別Ⅱ Ⅲ。
        3 基本參數(shù)及技術(shù)性能:
