Motor electromechanical relay RVA

AC1 NC

Used on commercial refrigeration and air conditioning, submersible pumps, floor cleaning equipment and other applications requiring high starting torque for motors from 1/2HP to about 3HP. RVA potential relay is designed to start single-phase motors which employ both start and run capacitor (CSR and CSIR configurations) for high starting torque. The most frequent applications include air conditioning, commercial refrigeration, heat pump, etc. The coil is energised by the potential of the start winding. When such voltage is raised up to the pick- up value, the contact will open and disconnect the start capacitor. The relay will remain energised until the start winding voltage is removed or decreases to less than the drop-out value.
