Q: What is the use of AC contactors?: Second: First, we should know the principle of AC contactor. He is using external power to the coil, resulting in electromagnetic fields.

Q: What parts of the contactor: No matter what extent the development of technology, ordinary AC contactor still has its important position.

Q: What about the release device and the contactor and the circuit breaker?: Circuit breaker according to its use is divided into high-voltage circuit breakers and low-voltage circuit breakers, high and low voltage line is more vague, generally more than 3kV called high-voltage electrical appliances.

Q: Seeking Star Triangle to start the contactor on and off the order and process: Start, in order to reduce the starting current it! It is certainly the star of the contactor first action it! The Then disconnect the star of the contactor, and then connected to the triangle contactor.

Q: Technical development of AC contactor: After the 1980s, countries to study the exchange of contactor electromagnet silent and energy-saving

Q: Three-phase AC contactor has several terminals that have a role: Hello, the general three-phase contactor a total of 8 points, three input, three output, there are two control points.

Q: Three-phase AC contactors have several useful clients?: Know the principle, you should figure out the connection of the external power supply, that is, the coil of the two contacts

Q: Determine whether the AC contactor can cut off the short circuit current?: arc extinguishing device, the general capacity of the larger AC contactor are equipped with arc extinguishing device, in order to quickly cut off the arc, from burning the main contact;

Q: How many AC contactors are there?: the main Contact mechanical connection of the auxiliary normally closed contact open, auxiliary normally open contact closed, thus turning on the power

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.
