CM1塑壳断路器【高品质、低价格】常熟塑壳断路器、接触器系列
◆用途
CM1系列塑料外壳式断路器其额定绝缘电压为800V(CM1-63为500V)，适用于交流50HZ，额定工作电压690V及以下(CM1-63为400V)，额定工作电流至800A的电路中作不频繁转换及电动机不频繁起动之用。断路器具有过载、短路和欠电压保护功能，能保护线路和电源设备不受损坏。
◆ 断路器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。断路器可垂直安装，亦可水平安装。该断路器具有体积小、高分断、短飞弧(部分规格为零飞弧)、带隔离、抗震动等特点，并通过了核工业条件(1E级)试验和船舶条件的试验，是国产产品中唯一能用于核工业基地的产品，更是陆地及船舶使用的理想产 二、1、过载和短路保护。
◇过载长延时保护。采用热动式(双金属元件)作过载长延时保护时，其动作源为I2R，交流的电流有效值与直流的平均值相等，因此不需要任何改制即可使用。但对大电流规格，采取电流互感器的二次侧电流加热者，则因互感器无法使用于直流电路而不能使用。 如果过载长延时脱扣器是采用全电磁式(液压式，即油杯式)，则延时脱扣特性要变化，最小动作电流要变大110％—140％，因此，交流全电磁式脱扣器不能用于直流电路(如要用则要重新设计)。
◇短路保护。 热动—电磁型交流断路器的短路保护是采用磁铁系统的，它用于经滤波后的整流电路（直流)，需将原交流的整定电流值乘上一个1．3的系数。全电磁型的短路保护与热动电磁型相同。 2、断路器的附件，如分励脱扣器、欠电压脱扣器、电动操作机构等；分励、欠电压均为电压线圈，只要电压值一致，则用于交流系统的，不需作任何改变，就可用于直流系统。辅助、报警触头，交直流通用。电动操作机构，用于直流时要重新设计。 3、由于直流电流不像交流有过零点的特性，直流的短路电流(甚至倍数不大的故障电流)的开断；电弧的熄灭都有困难，因此接线应采用二极或三极串联的办法，增加断口，使各断口承担一部分电弧能量。 4、除传统的热磁脱扣器外，电子脱扣器也得到了广泛应用。电子脱扣器的一个重要优点在于在环境温度变化的情况下，仍能稳定地工作。
