| Application |
| AC contactor(hereafter refer to ac contactor)is mainly used in power system with AC 50Hz(or 60Hz), the rated working voltage up to 660V, under the application category of AC-3, when the rated working voltage 380V, the rated operating current to 300A electrical, for the long-distance range making and breaking the electric circuit, and combines the electormagnetism starter with the suitable thermal overload relay or the electronic protector to protect against the possible overload electric circuit during operation(running). |
- Q: The key structure of the contactor
- Semiconductor contactor: The semiconductor contactor is a contactor that performs current operation by changing the conduction state and the open state of the circuit circuit.
- Q: The main structure of the contactor
- The contactor can operate at high frequencies, up to 1200 times per hour when the power is turned on and off.
- Q: How to connect the DC contactor to the circuit?
- and some sites are dangerous people can not go to the power cord can not run everywhere, which requires remote control, high current places, dangerous places with contactors We are in a safe place to control
- Q: What about the release device and the contactor and the circuit breaker?
- A circuit breaker is a switching device capable of closing, carrying and breaking current under normal circuit conditions and capable of bearing and driving current under abnormal circuit conditions for a specified period of time
- Q: What are the classification of contactors?
- DC current compared with the AC current, there is no periodic current value of the zero-crossing point, so the traditional contactor breaking circuit, the contact between the arc is more intense
- Q: How do I distinguish between contactors and circuit breakers?
- According to the different control voltage can be divided into DC contactor and AC contactor, its main accessories for the auxiliary contact.
- Q: The working principle of permanent magnet AC contactor
- From the power grid jump and jump, so as to maintain the stability of the production system
- Q: Why should the thermal relay be used with the AC contactor
- Thermal relay is used to protect the motor so that it is not overloaded, and motor-related, so with the use of the.
- Q: What is the energy saving function of traditional contactors?
- once the current becomes smaller so that the resulting electromagnetic force is not enough to overcome the reaction force of the spring, the contactor can not keep the closing state ,
- 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.
