详细介绍:
ESX系列相对应的是(EZD)系列塑壳断路器(以下简称断路器),主要用于交流50Hz或60Hz,
交流电压至660V(690V),在AC-3使用类别下工作电压为380V时,额定工作电流至170A的电路中,供远距离接通和分断电路之用,
并可与相应规格的热继电器组合成磁力起动器以保护可能发生过负荷的电路,接触器适宜于频繁地起动和控制交流电动机。
本断路器和ESX、ESE、EZD、CVS、CM1具有相同功能相应规格可等同相互使用。是CJ0、
CM2等老产品理想的更换代产品。
◆接触器,其产品使用寿命长,可靠性高,结构紧凑,型号齐全,能够适用于各种应用情况下的电动机控制与保护。
◆多种控制电压规格的交直流线圈可供选择。
◆产品使用寿命长,可靠性高。
◆附件齐全且通用。
◆导轨或螺钉安装均可,使用方便。
◆防触电安全罩设计,使用安全。
◆大容量接触器(100-800A)俊采用纯铁铁芯,线圈为可抽出式结构,更换方便。
◆大中容量(100-800A)的接触器线圈具有交、直流通用及110V-200V通用的特点。
◆断路器一般由触头系统、灭弧系统、操作机构、脱扣器、外壳等构成。 当短路时,大电流(一般10至12倍)产生的磁场克服反力弹簧,脱扣器拉动操作机构动作,开关瞬时跳闸。当过载时,电流变大,发热量加剧,双金属片变形到一定程度推动机构动作(电流越大)。
