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.
