This power relay uses high amperage capacity contacts to transfer power
to large fans, pumps or lighting systems requiring high voltage or
amperage service. Prevents premature failure of equipment, timers or
other switching controls due to excessive current draw. Allows
switching of 240 VAC equipment with 115 VAC controls. Prevents
equipment overheating due to insufficient power supply. Use the HAR-1
to operate 115 or 240 volt high draw equipment. Provides 30 amp
switching capacity with 115 VAC trigger input from control device.
Approved for indoor use only.
