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.

Q:Can the AC contactor cut off the short circuit current?

Because the AC contactor is only a switch-type device, no current detection and feedback device, so in practice, often with the appropriate thermal relay or electronic protection device into an electromagnetic starter, in order to protect the circuit may occur overload or phase failure.

Q:The main structure of the contactor

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:Application of Virtual Instrument Technology in Parameter Detection of Switchgear

The traditional detection method has the advantages of slow speed, large error and inaccurate measurement

Q:How is the DC contactor connected to the circuit

with the benefits of contactor is easy to operate, reduce the risk factor when operating;

Q:How to choose the contactor

for example, the circuit current is 218A, the 250A contactor should be selected

Q:A brief introduction to the power contactor

The AC contactor relies on a spring return after power failure. The other half is the activities of the core, the structure and fixed iron core, to drive the main contacts and auxiliary joints of the short

Q:Permanent magnet AC contactor main performance?

The six parts, it also determines the operating mechanism can have anti-shake function.

Q:The difference between electromagnetic contactor and AC contactor

C contactor is also a kind of electromagnetic contactor, because the AC contactor is the use of alternating current to let the coil produce magnetic field (magnetic flux), so that contactor to pull.

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
