Lennox 18Y93 Control Board Time Delay Relay

The Lennox 18Y93 Control Board Time Delay Relay is a heavy duty control component used in controlling Lennox HVAC equipment, commonly used in commercial or industrial applications. This small but mighty device controls the delivery of power with better timing and can easily handle large cooling systems. Meant for 460V, 60Hz, 3-phase electrical systems, the 18Y93 regulates the time when power is supplied to different components of a system including compressors or motors. This time delay is to avoid spikes and to ensure that each part starts up in the right order for the large cooling systems. Because of the high voltage and its particular operation, make sure it is compatible with your Lennox system before using it.
