Contactor
Contactor operation is achieved by energizing an operating coil in response to a call for heat from the immersion
thermostat. Upon a call for heat, one or more contactors will energize all heating elements simultaneously. The
operating coils are voltage specific, When contactor replacement is required be sure to order the proper operating coil
base on the voltage rating found on the rating plate located on the front of the water heater.
