KNOWLEDGE BASE --- What is the difference between AC contactor and DC contactor?
There are some difference between AC contactors and DC contactors. Here is the main difference between them.
1. Iron core
The eddy current and hysteresis loss will be generated on the iron core after the coil is connected to the alternating current. Therefore, the iron core of the AC contactors is made of 0.5mm thick silicon steel sheets coated with insulating paint on both sides and is usually made into an E shape iron core. While the DC contactors have no eddy current loss, so that their iron cores are usually made of mild steel and mostly they are U-shaped.
Because the magnetic force of the AC contactor core is affected by the zero crossing of the alternating current, it will be repeatedly closed and disconnected under the reaction force of the spring, so that the AC contactor will generate vibration and noise, which will have bad impact on the work. In order to eliminate vibration and noise, a short-circuit ring is usually added to the iron core to solve the problem. Because the iron core is composed of multiple silicon steel sheets, the addition of a short-circuit ring is equivalent to shifting a part of the magnetic field, so that the electromagnetic force is divided into two parts with different phases, which solves the problem of electromagnetic force zero crossing.

2. Arc extinguishing system
The AC contactor uses a grid sheet arc extinguishing device, however, the DC contactor adopts a magnetic blowing arc extinguishing device.

3. Number of coil turns
In addition to the resistance of the coil itself, the impedance of the AC contactor coil also has inductive reactance. Because the AC contactor coil will generate inductive reactance after being connected to the alternating current, the hindering effect of the inductive reactance on the current is far greater than the resistance of the coil itself, so the number of turns of the AC contactor coils is generally relatively less than that of DC contactor coils. Because the coil of the DC contactor is connected to DC and the coil impedance is only its own resistance.

4. Operating frequency
Since the current of the AC contactor coil is related to the core gap. Namely, the larger the gap is, the greater the current is. Long-term frequent closing and disconnection of AC contactors will cause the coil to overheat and burn out, so it is not suitable for occasions with frequent switching.
Howerver, the coil current of the DC contactor has nothing to do with the core gap. The coil current of the DC contactor remains the same before and after the pull-in. Therefore, the frequent pull-in and disconnection of the DC contactor will not cause the coil to overheat, which is suitable for frequent switching occasions.
