That's 30 amps per contact, right? The one we used on the 2008 TechnoKats robot's continuous-rotation arm has eight contacts. Use four of them for a pair of 30A supply and return lines, and you still have four left over for an encoder if you want.

(The list price of such things might be higher than the single-component cost limit, but many suppliers have an educational discount that they offer to any team who asks for it.)
