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: On the difference between the contactor and the relay: At this time, you can choose an original as a contactor to use the electrical appliances as the control circuit with the off, the contactor in this case is the role of the relay.

Q: What is the use of AC contactors?: The power is applied and the contact point is disconnected after power failure

Q: The Role of Virtual Instrument Technology in the Parameter Detection of Switchgear Cabinet: In the literature, a time parameter detection circuit is mentioned. The main components of the circuit are single-chip microcomputer

Q: How to choose the contactor: rated current multiplier refers to the motor starting current and rated current ratio, the general motor starting current is 5-7 times the rated current (RMS), converted to the peak, then the maximum to 12 times

Q: Seeking Star Triangle to start the contactor on and off the order and process: The picture of the triangle - the triangle shows you! And explain the process!

Q: Contactor frequent pull is how the matter: Coil voltage is too low, need to check the control coil power is normal.

Q: What is the main component of the contactor?: one of which is fixed with a coil and a working voltage. select. In order to stabilize the magnetic force, the suction surface of the core is short-circuited. The AC contactor relies on a spring return after power failure.

Q: What is the energy saving function of traditional contactors?: And permanent magnet AC contactor to keep the relays depends on the permanent magnetic force, without the need for electromagnetic current generated by the coil to close the closing

Q: What are the types of AC contactors?: In order to quickly extinguish the arc when the break, usually contactor are equipped with arc extinguishing device, the general use of semi-sealed vertical seam clay hood, and with a strong magnetic blown arc.
