Lennox 74H01 Potential Relay

The Lennox 74H01 Potential Relay is an essential part created for Lennox HVAC systems. This small device works as a control switch and regulates electrical currents in the system. The relay gets commands from the thermostat and by the help of its internal working, it can switch on/off the electrical contacts. This enables high current up to 35 Amps to freely charge the compressor or other high power devices when required, and block the current when cooling or heating cycle is done. The relay ensures efficient working of the Lennox HVAC system due to the accurate regulation of power supply.
