MARS 19164 Potential Relay 395V 164

The MARS 19164 Potential Relay serves HVAC systems as a high-quality relay that helps single-phase compressor motors start-up by connecting the start capacitor during operation. The relay operates at 395V and supports 35A of current to link the start capacitor to the circuit briefly until the motor reaches its designated speed where it automatically disconnects. The Model 164 relay includes tab-type installation features which makes it popular for use in air conditioners, heat pumps, and refrigeration units. The relay provides three main advantages that enhance compressor performance and extend motor longevity while minimizing electrical strain.
