Contactor main classification

2021-04-19

According to the form of the main contact connection circuit: DC contactor, AC contactor. According to the operating mechanism: electromagnetic contactor, Permanent Magnet contactor.

The permanent magnet AC contactor is a micro-power contactor formed by replacing the conventional electromagnet drive mechanism with a permanent magnet drive mechanism by utilizing the principle of the same polarity repulsive and opposite phase attraction of the magnetic pole. Domestic mature product models: CJ20J, NSFC1, NSFC2, NSFC3, NSFC4, NSFC5, NSFC12, NSFC19, CJ40J, NSFMR.

A permanent magnet with a fixed polarity on the contactor linkage mechanism interacts with a variable polarity soft magnet solidified on the base of the contactor to achieve the purpose of suction, hold and release. The variable polarity of a soft magnet is generated by an electronic module that is solidified together with a positive and negative pulse current of ten to twenty milliseconds, resulting in different polarities. According to the needs of the site, the control electronic module is used to control the set release voltage value, and the reverse pulse current can be delayed for a period of time to achieve the purpose of low voltage delay release or power failure delay release, so that the motor is controlled. Keep the production system stable by avoiding the grid from sloshing.

According to the driving method, it is divided into: hydraulic contactor, pneumatic contactor and electromagnetic contactor.

According to the action mode, it is divided into: direct-acting contactor and rotary contactor.

 AC Contactor switch mainly used for making or breaking circuit at a long distance, suitable for controlling starting\stopping\reversing of AC motor. AC Contactor of korlen conforms to the requirement of IEC60947-4-1& GB14048.4 standards.

Except AC Contactor, there are many different types of low voltage electric appliances, such as Thermal Relay,Manual Motor Startor ,led light, Circuit Breaker, etc.
