Introduction:

CJ20 series AC contactors are suitable for frequency 50Hz,rated voltage up to 660V,rated current up to 630A,It is mainly used for making or breaking electric circuits at a long distance & for frequent starting & stopping, controlling AC motors.

It is used in combination with thermal relay to compose a magnetic motor starter.

Q:Research on Relay Parameter Detection Technology Based on Single Chip: The cost of the device is high, which is of great reference value for the development of the test equipment. [2]

Q:Traditional communication contactor long life and long reliability?: Compared with the traditional contactor, permanent magnet AC contactor in closing, in addition to the same electromagnetic force, but also has the role of permanent magnetic force,

Q:What is the difference between the contactor and the relay?: How to distinguish? The difference is that Look at their specific use.

Q:What parts of the contactor: AC contactor is made as a whole, shape and performance are constantly improving, but the function is always the same.

Q:What is the difference between a release, a contactor and a circuit breaker?: Detector is a switch circuit breaker or thermal relay inside a body, popular say that some of the monitoring circuit to reach a certain degree of time to trigger the trigger, the purpose is to control the circuit break.

Q:What are the characteristics of permanent magnet AC contactors: ; 2. Control the power supply voltage real-time detection; 3. Release energy storage (some also have to absorb energy, but not necessarily)

Q:How does the contactor interlock?: The normally closed contacts of the KM2 contactor are connected in series to the coil circuit of the KM1 contactor, but if a contactor is welded

Q:What is the noise-free function of traditional contactors?: The traditional AC contactor is closed by the coil power to make the silicon steel sheet to produce electromagnetic force

Q:What causes the AC contactor to be damaged: Damage to the product itself (such as the coil broken or burned, the mechanical moving part was stuck, the shaft rust or skew, etc.) 5. Contact spring pressure and overtravel. Increase the supply voltage

Q:What is the main component of the contactor?: The power of the AC contactor is derived from the magnetic field generated by the AC core coil. The solenoid core is made of two "mountain" shaped silicon steel sheets
