HAR-1 High Amperage Relay, 120 or 240 Volt 30 Amp Switch, 120 Volt Trigger
The HAR-1 is a High Amperage Relay. It has a power input, power output and a trigger power cord. The power input and output must be hard wired to your circuit. The trigger power cord operates on 120 volts and draws very low wattage. When power is applied to the trigger the input is connected to the output powering your device. It's used to 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. 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.
If you are unsure of proper installation consult a certified electrician or the equipment manufacturer for detailed instructions.
The diagram at the right shows the HAR-1 relay being used to supply switched power to lighting equipment. The timer is used to trigger contact closure of HAR-1 to operate lighting during desired hours. When using 240 volt service, up to six 1000 watt ballast's could be switched.
It can also be used for supplying power for large or multiple fan installations. The atmospheric controller CT-DH-1, 2 or 3 will trigger fan functions according to temperature and humidity conditions.
