Littelfuse 235P PumpSaver 230VAC (5-15HP)

Littelfuse SymCom 235P Single-Phase PumpSaver® 230VAC (5-15HP)  is a pump monitor designed to protect single-phase pumps from dry-well, dead-head, jammed impeller, overvoltage and undervoltage conditions. The PumpSaver®Plus Model 235 protects 5-15HP 230V pumps (external current transformer required). 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 235P 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 called the Informer (sold separately). Infrared LED communicates directly with the PumpSaver Plus making it easy to diagnose those hassling pump issues.
