Aug 05, 2014 · A multifunction relay can protect a medium-voltage motor starter with a vacuum contactor. While a bimetallic thermal overload relay could be used (as is done for many low-voltage motors), a greater measure of protection is required for medium-voltage motors because of the cost and the critical role of these motors in many applications.
