If you absolutely must use an AC contactor in a DC application, certain modifications can be made to mitigate risks: 1. Derating the Contact Ratings : Reduce the current load to a fraction of the AC rating (typically 50% or less) to minimize the risk of arc-related damage.
Polarized High-Voltage Contactors. Polarized contactor relays have optimized magnetic blowouts that maximize arc quenching. Permanent magnets on the sides of the contact chamber create magnetic fields that bend the arc. By causing the arc to travel a longer distance, resistance is increased, and the arc extinguishes faster.

Both AC and DC contactors can be distinguished based on the number of coils. The DC contactor has more coils than the AC contactor, which has fewer coils. Two-phase winding coils should be used in series by the contactor if the primary loop current is too high (i.e., greater than 250A).
