Check to see if the cause of it stopping is if overload tripped, if so as Scott intimated, it will need higher capacity overloads, if heaters (3) then you need to get the number of the higher current type, is it an Allen Bradley contactor? if so there should be a code # on printed on the outside of the heater.
The motor takes approximately 2x current on 220.
