Compressor Start Relay SPST 50A for Trane and American Standard Central Air Conditioners, Replaces RLY03210

A single-pole single-throw (SPST) start relay for Trane and American Standard central air conditioners and compressors. It gives the compressor extra current at startup, then switches out once the motor reaches operating speed. A failed start relay often leaves the compressor humming, slow to start or not starting at all.
