    塑料外殼式斷路器商品基本參數(shù)

    產(chǎn)品用途:
    RMM2系列塑料外殼式斷路器額定絕緣電壓690V,主要用于交流50Hz,額定工作電壓400V,額定電流630A及以下的配電網(wǎng)絡(luò)中,作為分配電能和保護(hù)線路及電源設(shè)備免受過載、欠電壓、短路等故障的危害。斷路器也可對電動機進(jìn)行過載、欠電壓和短路保護(hù)。RMM2塑料外殼式斷路器帶接地故障保護(hù)型過電流脫扣器后,除了原有的過載、短路保護(hù)功能之外,新增加了接地故障保護(hù)功能?梢詫σ话氵^電流保護(hù)裝置不能檢測出的接地故障引起的火災(zāi)或其它危險提供保護(hù)。它帶通訊模塊后,能將斷路器上的信息通過RS485接口上傳到控制計算機上,并能通過計算機操縱斷路器的合閘和斷開。
