Littelfuse PumpSaver®Plus Insider

Littelfuse SymCom Single Phase PumpSaver®Plus Insider are designed to protect single-phase pumps from dry well, dead head, jammed impeller and over and undervoltage conditions.

A calibration adjustment allows the Insider-P to be calibrated to your specific pumping applications, thereby reducing the possibility of fails or nuisance tripping. A unique microcontroller-based voltage and current sensing circuit constatly monitors the incoming power for fluctuations, overcurrent and undercurrent. When an abnormality, such as loss of suction is detected, the PumpSaver®Plus deactivated 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 down to zero or power is removed and reapplied, the PumpSaver®Plus reactivated its output relay, allowing the pump to turn back on.
