按主触点连接回路的形式分为：直流接触器、交流接触器。
按操作机构分为：电磁式接触器、永磁式接触器。
永磁交流接触器是利用磁极的同性相斥、用永磁驱动机构取代传统的电磁铁驱动机构而形成的一种微功耗接触器国内成熟的产品型号：CJ20J、NSFC1、NSFC2、NSFC3、NSFC4、NSFC5、NSFC12、NSFC19、CJ40J、NSFMR。
According to the main contact circuit is divided into: DC contactor, AC contactor.
According to the operating mechanism is divided into: electromagnetic contactor, permanent magnet contactor.
Permanent magnet AC contactor is used, a magnetic repulsion with the permanent magnet drive mechanism to replace the traditional electromagnet drive mechanism and the formation of micro power contactor mature domestic product type: CJ20J, NSFC1, NSFC2, NSFC3, NSFC4, NSFC5, NSFC12, NSFC19, CJ40J, NSFMR.
Contactor and circuit breaker
接触器和断路器的区别/接触器
1, circuit breaker to do the main protection. It is commonly used in the protection of the three section protection, overload protection, short circuit short delay, short circuit delay. There are some undervoltage, overvoltage protection functions. Specific depending on the brand, model and. It can be divided into manual or electric. There are three ways to install, such as fixed, drawer type. According to the size of the current and the voltage level can be divided into low-voltage molded case circuit breaker, low voltage circuit breaker and high voltage vacuum circuit breaker. According to the different tripping curve can be divided into different use occasions. There's a big difference between the fuse and the fuse.
1、断路器主要做保护作用。它的保护目前比较常用的是三段保护，既过载保护、短路短延时、短路长延时。还有一些欠压、过压等保护功能。具体视品牌、型号而定。它的分合闸可以手动也可电动。安装方式有固定式、抽屉式等三种方式。根据电流的大小和工作电压的等级可以分为低压塑壳断路器、低压框架断路器和高压真空断路器。根据脱扣曲线的不同可以分为不同的使用场合。和保险丝还是有很大区别的。
2, the contactor is mainly used for industrial control, the general load to the motor in the majority, of course, there will be some heaters, double power switch and other occasions to use. The on-off of the contactor is realized by controlling the voltage of the coil. According to the different structure of the arc extinguishing, it can be divided into the vacuum contactor and the common contactor. According to different control voltage can be divided into DC contactor and AC contactor. Its main accessory is auxiliary contact. And it does not have short circuit protection and overload protection, it must be used in conjunction with fuse, thermal relay.
2、接触器主要做工业控制用，一般负载以电机居多，当然会有一些加热器、做双电源切换等场合使用。在接触器的通断是通过控制线圈电压来实现的。根据灭弧的不同结构可以分为真空接触器和普通接触器。根据不同的控制电压可以分为直流接触器和交流接触器。它的主要附件为辅助触点。而且本身不具备短路保护和过载保护能力，因此必须与熔断器、热继电器配合使用。
ABB接触器铭牌额定电压是指主触点上的额定电压。通常用的电压等级为：直流接触器：110V，220V，440V，660V等档次。交流接触器：127V，220V，380V，500V等档次。如某负载是380V的三相感应电动机，则应选380V的交流接触器。
