    商品基本参数

    RMM2塑料外壳式断路器产品用途:
    RMM2塑料外壳式断路器额定绝缘电压690V,主要用于交流50Hz,额定工作电压400V,额定电流630A及以下的配电网络中,作为分配电能和保护线路及电源设备免受过载、欠电压、短路等故障的危害。断路器也可对电动机进行过载、欠电压和短路保护。RMM2塑料外壳式断路器带接地故障保护型过电流脱扣器后,除了原有的过载、短路保护功能之外,新增加了接地故障保护功能。可以对一般过电流保护装置不能检测出的接地故障引起的火灾或其它危险提供保护。它带通讯模块后,能将断路器上的信息通过RS485接口上传到控制计算机上,并能通过计算机操纵断路器的合闸和断开。
