Can I use my regular contactor that breaks in vacuum for DC applications?

Svar:

Vacuum contactors use encapsulated contacts with vacuum instead of air as the medium to eliminate arcing. Vacuum contactors are only applicable for use in AC applications. The AC arc generated by the opening of the contacts will itself be extinguished at the zero crossing of the current waveform, the vacuum preventing a re-ignition of the arc across the open contacts.
