Specifications

1.rated voltage up to 1000V
2.rated operation current up to 780A
3.Can install contact blocks
4.high quality long life

CJX2-F series AC contactors are suitable for frequency 50/60Hz, rated insulation voltage up to 1000V, rated operation current 115~780A under AC-3 duty. It is mainly used for making and breaking electric circuits at a long distance & for frequent strarting, stopping & controlling AC Motors. It is used in combination with thrmal relay to compose a magnetic motor starter. The products comply with IEC6047-4.

Q: What is the difference between a contactor and a circuit breaker?: Depending on the specific brand, model may be. Its sub-closing can be manually or electrically

Q: Basic classification of AC contactors: The main contact function is to connect and break the main circuit, control the larger current, and auxiliary contact is in the control loop to meet the requirements of various control methods.

Q: The contactor is mainly composed: The service life of the contactor is very high, the mechanical life is usually several million to ten million times, and the electrical life is generally several hundred thousand to several million times.

Q: What are the principles of selection of contactors?: When the rated current of the contactor main contact is selected, the rated current of the main contact shall be equal to the rated current of the load

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: What is the formulation of the contactor?: When controlling the motor, the rated current of the main contact should be greater or slightly larger than the rated current of the motor

Q: What is the scope of use of AC contactors?: Know the principle, you should figure out the connection of the external power supply, that is, the coil of the two contacts

Q: With long life, long reliability is the advantages of traditional communication contactor: but also has the role of magnetic repulsion, these two functions so that the opening speed is much faster than the traditional contactor

Q: Three-phase AC contactors have several useful clients?: . And note whether the contact point is normally closed or normally open. If there is self-locking control, according to the principle of the line on it.

Q: What is the effect of the contactor coil parallel capacitor?: Capacitors at both ends of the voltage can not be special changes, and the capacitor can delay and reduce the coil's reverse electromotive force, Reduce interference, extend the life of contacts.
