Emax框架断路器秉承ABB产品一贯的优良传统,性能卓越、外形更紧凑,节约了开关柜的空间。断路器采用模块化的设计,安装更方便。全系列采用相同的高度及深度,更容易在低压开关柜上整合,大幅度减少了安装的尺寸。
空气断路器全钢结构设计,外壳采用特殊聚酯材料,耐腐蚀、隔热、绝缘能力强且具备很高的阻燃特性,即使在火焰中也不易燃烧,有效的防止了电气火灾的进一步扩散。
限流型开关选用多重分断和独特灭弧室设计等限流技术,提高了断路器的极限分断能力,减少了短路发生时电网的允通能量,可大幅度地降低预期故障电流的峰值,降低电动应力和热应力,减少电缆及母排的尺寸规格。
新型电子脱扣器PR122/P和PR123/P可配备通讯模块,通过常用的Modbus RTU通讯协议,与网络中其他工业电子装置实现数据交换和信息传送。通过通讯网络可读取所有保护脱扣器的信息,并且可以对断路器进行遥信、遥控、遥调。
新型空气断路器具有E1、E2、E3、E4和E6五种类型,固定式和抽出式,额定不间断电流从800A到6300A,分断能力高达150KA(415V)。同一框架下不同额定电流和分断能力的断路器均具有相同的尺寸。另外,也具有限流型断路器,特别推荐使用在有高短路电流的场合。断路器附件完全通用,从前面进行安装,无需任何内部电缆布线。
