Contactor
Contactor operation is achieved by energizing a 120 volt operating coil located within the contactor 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. Optionally, time delay sequencers may be used to stage contactor activation
thereby reducing the inrush of current to the water heater.
