    Does anyone know of a relay that works on 120 and 480? I need a relay with a range like 60vac-600vac, any ideas?

    Basically what I need to know is if any voltage is present at all. Also, it doesn't have to be 3 phase a single phase device that I repeat would work also.

    You could make a circuit up that would pick up one relay.
    It would involve a 3ph rectifier off the supply, a resistor from the +v to feed the gate of a Mosfet which in turn would pick up a DC relay of your choice.
