YCM1系列塑料外壳式断路器(以下简称断路器），是采用国际先进设计和制造技术研制开发的新型断路器之一，按照其额定极限短路分断能力(Icu)的高低，分为C型(基本型)，L型(标准型)，M型(较高分断型),H型(高分断型)四类。该产品具有体积小,分断高,飞弧短，抗振动的特点，是陆地及船舶使用的理想产品。其额定绝缘电压800V(YCM1-63为500V),适用于交流50Hz,额定工作电压690V(YCM1-63为400V)及以下的电路中作不频繁转换和电动机不频繁起动之用。断路器具有过载，短路和欠电压保护装置，能保护线路及电源设备不受损坏。本断路器可垂直安装(即竖装)，亦可水平安装(即横装)。本产品符合IEC60947-2，GB14048.2标准。1.按过电流脱扣器额定电流(A)分：YCM1-63为(6)、10、16、20、25、32、40、50、63A九级；YCM1-100为(10)、16、20、25、32、40、50、63、80、100A十级；YCM1-225为100、125、140、160、180、200、225A七级；YCM1-400为225、250，315、350、400A五级；YCM1-630为400、500、630A三级。YCM1-63L/3300/6AYCM1-63L/3300/6AYCM1-63L/3300/10AYCM1-63L/3300/16AYCM1-63L/3300/20AYCM1-63L/3300/25AYCM1-63L/3300/32AYCM1-63L/3300/40AYCM1-63L/3300/50AYCM1-63L/3300/63AYCM1-63L/3310/6AYCM1-63L/3310/10AYCM1-63L/3310/16AYCM1-63L/3310/20AYCM1-63L/3320/25AYCM1-63L/3320/32AYCM1-63L/3320/40AYCM1-63L/3320/50AYCM1-63L/3320/63AYCM1-63L/3330/6AYCM1-63L/3330/10AYCM1-63L/3330/16AYCM1-63L/3330/20AYCM1-63L/3340/25AYCM1-63L/3340/32AYCM1-63L/3340/40AYCM1-63L/3340/50AYCM1-63L/3340/63AYCM1-63L/3350/6AYCM1-63L/3350/10AYCM1-63L/3350/16AYCM1-63L/3350/20AYCM1-63L/3350/25AYCM1-63L/3360/32AYCM1-63L/3360/40AYCM1-63L/3360/50AYCM1-63L/3360/63AYCM1-63L/3370/6AYCM1-63L/3370/10AYCM1-63L/3370/16AYCM1-63L/3370/20AYCM1-63L/3370/25AYCM1-63L/3370/32AYCM1-63L/3370/40AYCM1-63L/3370/50AYCM1-63L/3370/63AYCM1-63M/3300YCM1-63M/3310YCM1-63M/3320YCM1-63M/3330YCM1-63M/3340YCM1-63M/3350YCM1-63M/3360YCM1-63M/3370YCM1-63/4300YCM1-100L/3300YCM1-100L/3310YCM1-100L/3320YCM1-100L/3330YCM1-100L/3340YCM1-100L/3350YCM1-100L/3360YCM1-100L/3370YCM1-100M/3300YCM1-100M/3310YCM1-100M/3320YCM1-100M/3330YCM1-100M/3340YCM1-100M/3350YCM1-100M/3360YCM1-100M/3370YCM1-100/4300YCM1-225L/3300YCM1-225L/3310YCM1-225L/3320YCM1-225L/3330YCM1-225L/3340YCM1-225L/3350YCM1-225L/3360YCM1-225L/3370YCM1-225M/3300YCM1-225M/3310YCM1-225M/3320YCM1-225M/3330YCM1-225M/3340YCM1-225M/3350YCM1-225M/3360YCM1-225M/3370YCM1-225/4300YCM1-400L/3310YCM1-400L/3320YCM1-400L/3330YCM1-400L/3340YCM1-400L/3350YCM1-400L/3360YCM1-400L/3370YCM1-400M/3300YCM1-400M/3310YCM1-400M/3320YCM1-400M/3330YCM1-400M/3340YCM1-400M/3350YCM1-400M/3360YCM1-400M/3370YCM1-400/4300YCM1-630L/3300YCM1-630L/3320YCM1-630L/3330YCM1-630L/3340YCM1-630L/3350YCM1-630L/3360YCM1-630L/3370YCM1-630L/3370YCM1-630M/3300YCM1-630M/3310YCM1-630M/3320YCM1-630M/3330YCM1-630M/3340YCM1-630M/3350YCM1-630M/3360YCM1-630M/3370YCM1-630/4300
