as Jack said, you'll have to find a relay rated for your voltage. But, just to reiterate, make sure you find something that is DC rated. A 120V AC rated relay will not be able to break 120 VDC (I think it's only like 38VDC, some of the AC relays will also have a lower DC rating).

I had purchased a 150VDC 20A relay from one of the EV suppliers... shoot, i can't figure out where I got it, but it was about $20.
