Of course a coil and heaters for 220 volt operation are rarer than hen’s teeth. Rather than just buying a new contactor with a thermal overload relay, I took the following approach:
Coil
Convert 220 volts to 440 volts using the center topped primary of a 480/240 to 120 volt, 50 VA transformer (like an auto transformer).
Thermal Overload
Buy a new, adjustable thermal overload relay with an automatic reset to replace the original.
Start Button Lamp
Use the 120 volt secondary to power a 120 vac LED pilot light.
Total cost was around $100.
