RVA RelaysRVA, 35 amp and RVAH, 50 amp potential relays are designed for use with single-phase motors that use start and run capacitors (CSR and CSIR motor configurations), and other "high starting torque" motor applications. In these normally closed relays the coil is energized by the electrical potential of the start winding. When the voltage in the winding is raised to the pick-up value the relay contact will open and disconnect the start capacitor. The relay will remain energized until the voltage decreases to less than the drop-out voltage value. Typical applications include air conditioning and refrigeration compressor, heat pump, submersible pump and other hard start and high SEER product applications.
