no way! ∵ in the electromagnets of AC and DC contactors, the factors that affect the coil current are different. If they are exchanged, either the coil can not work normally or the coil will be burned immediately.

    When the DC contactor works, the coil does not induce electromotive force, so the excitation current is limited by increasing the coil resistance, so the wire diameter is small. If it is connected to the AC circuit, the coil itself will induce a large potential, so the current flowing through is very small, and the electromagnetic attraction generated will not be enough to make the armature close, so the DC contactor used for AC circuit will not work normally.

    On the contrary, AC contactor will induce electric potential when its coil is working, which will limit the current when it is working normally. In order to make it have enough suction, the wire resistance of the coil should be smaller, so the wire diameter is smaller. If it is connected to the DC circuit, because the potential can not be induced, under the same voltage, it will produce a very large current (more than ten or even dozens of times of the rated current), which will make the coil of the contactor burn out immediately.
