Littelfuse SymCom 111-Insider-P PumpSaver 115V (1/3-1/2HP)

LittelfuseSymCom 111-Insider-P 1-Phase PumpSaver®Plus provides single-phase protection for submersible pumps with an input voltage of 115 V ac and input load range from 1/3–1/2 hp. Its output load rating is 1/2 hp @ 120 VAC (17A maximum). The PumpSaver®Plus Model 111-Insider-P fits inside 1/3 and 1/2 hp 115V control boxes and is 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 false or nuisance tripping. A unique microcontroller based voltage and current sensing circuit constantly monitors the incoming power for fluctuations, over current 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 down to zero or power is removed and reapplied, the PumpSaver®Plus reactivates its output relay, allowing the pump to turn back on.

The 111-Insider-P communicates with a hand-held diagnostics tool called the Informer (sold separately). The Informer displays 15 parameters including calibration points, trip points, running points, and last faults.
