Tips: Difference between DC contactor and AC contactor

The difference between a DC contactor and an AC contactor is in the core and coil.

There is eddy current in the electromagnet core of AC contactor, so the electromagnet core is made to be stacked one by one. To prevent electromagnetic release at the moment of zero crossing, a short-circuit ring is added to the electromagnet core, the number of coil turns is small, the current is large, and the wire diameter is thick.

The electromagnet core of the DC contactor is an integral iron core with a slender coil and a particularly large number of turns. If the AC and DC contactors are connected incorrectly, the DC power is connected to the AC contactor, and the coil will burn immediately. The AC power is connected to the DC contactor, the contactor cannot be closed.
