  • Product Description
111P-ENCL The 111P, 233P-1.5 and 233P single-phase PumpSaver relays protect pumps from dry-well, dead-head, jammed impeller, rapid-cycling, and overvoltage/undervoltage, whether the pressure switch is mounted before or after our unit. A calibration process allows the relay to be calibrated to your specific pumping application, thereby reducing the possibility of false or nuisance tripping. A proprietary microcontroller based voltage, power factor and current-sensing circuit constantly monitors for power fluctuations, overcurrent and underload conditions. When an abnormality, such as loss of suction, is detected, the relay deactivates its output relay and directly disconnects the pump motor and begins its user-selectable “Restart Delay” (dry-well recovery) timer. When the timer expires or power is removed and reapplied, the unit reactivates its output relay and allows the pump to turn back on. FEATURES
