Single Phase Preventer

Jay Proton's Single Phase Preventer protects three-phase induction motors from the damaging effects of single phasing, phase reversal, and voltage imbalance. Automatic reconnection after supply restoration ensures uninterrupted pump operation.

Single phasing (loss of one phase) is one of the most common causes of three-phase motor burnout. The preventer continuously monitors all three phases and immediately disconnects the motor contactor when a fault is detected.


Key Features

  • Protection against single phasing (phase loss)
