Can an automotive relay handle an armature voltage of more than 12 volts?

I need a relay to operate on a low coil voltage but with an armature capable of operating at 96 volts; is a standard automotive 12v relay capable of handling an armature voltage of more than 12 volts? Is the 12v rating on automotive relays for the coil voltage or the armature voltage or both?

thanks in advance!


@wildmann thank you very much; i just wanted to make sure that the armature/contacts won't arc over at 96 volts

    The 12 volt rating is for the coil and will work without problem up to around 18 volts.

    The contacts {you are calling armature] will work on 96 volts as you ask.They are rated in amps,as long as they do not exceed 20 amps,the voltage doesn't matter.

    Glow plugs are in basic terms mandatory to warmth the combustion chamber to ease chilly climate commencing. as quickly as began, or in a heat ecosystem, a diesel would not desire the glow plugs. i could do a compression attempt first and then verify to be sure if the compression is interior spec. without compression, no diesel or gas engine will run. additionally verify the timing. Then verify to be sure if the engine is getting gas.... meaning checking operation of the gas pump and making specific the gas filter out (or gas filters... some diesels have better than one) isn't clogged.
