Danfoss 8173022 Start Relay

The Danfoss 8173022 Starting Relay is an electrical control component used in refrigeration compressors to manage motor start-up operation in HVAC systems. It temporarily connects the start winding during initial power-up and then disconnects it once the motor reaches running speed. It is placed in cooling equipment where controlled compressor starting is required for stable system performance of the unit. It supports coordination between electrical windings and control circuits, reduces electrical stresses and operating damage during repeated system cycling, and continuous use.
