Because of the difference, you usually find DC contactors have complicated coils, usually two windings, using both windings to pull in, and one winding to hold once pulled in. Usually they are pre wired using one of the auxilliary contacts for this. In short, you need to buy a contactor / relay designed for 12V DC. The one you have won't work.[/quote]
