Need help finding a relay Answered

My school's building a biodiesel-hybrid car. Is there something like a normally closed relay that can be opened when the voltage goes over 165V. What should I be looking at?

You can buy over-voltage relays off the shelf from people like Siemens, ABB, Cutler-Hammer etc

You're looking for either an HV relay or a contactor. Do a Google search for "high voltage relay" to help narrow your search down, then check some of the resulting companies' product lists for the right coil voltage range. You'll need to build in appropriate protection into the circuit as well.
