Littelfuse SymCom 111P-ENCL PumpSaver 115V (1/3-1HP)

Littelfuse SymCom Model 111P-ENCL PumpSaver Plus with NEMA3R Enclosure is a pump monitor designed to protect single-phase pumps from dry-well, dead-head, jammed impeller, over voltage and under voltage conditions.

PumpSaver®Plus Model 111P protects 115V pumps rated 1/3-1hp. Typical applications include submersible pumps, centrifugal pumps, circulating pumps, cooling pumps, environmental pumps, residential water wells, commercial water wells, irrigation wells, and golf course systems.

A calibration adjustment allows the Model 111P to be calibrated to specific pumping applications, thereby reducing the possibility of false or nuisance tripping. A unique microcontroller-based voltage and current-sensing circuit constantly monitors the incoming power for power fluctuations, overcurrent, and undercurrent. When an abnormality, such as loss of suction, is detected, the PumpSaver®Plus deactivates its output relay and directly disconnects the pump motor. The PumpSaver®Plus then begins its user-selectable restart delay (dry-well recovery) timer. When the timer counts to zero or power is removed and reapplied, the PumpSaver reactivates its output relay and turns the pump back on.

Also available from SymCom is a easy to use hand held diagnostics tool (sold separately). Infrared LED communicates directly with the PumpSaver Plus making it easy to diagnose those hassling pump issues.

Note: The use of flow restrictors, unusually high head pressures or low water conditions at the time of calibration may interfere with the detection of dead-head and dry-run conditions. Contact Symcom for information on activating the special underload high sensitivity mode built into this Pump Saver controller.
