The Trane RLY3148 is a genuine OEM compressor start relay (potential relay) used in select Trane and American Standard air-conditioning and heat pump systems. The relay controls the compressor start winding circuit by temporarily energizing the start circuit during compressor startup and disconnecting it once the motor reaches operating speed. This helps provide reliable compressor starting and reduces electrical stress on compressor components.
