Littelfuse SymCom 231-Insider-P PumpSaver 230V (1/3-1HP)

Littelfuse SymCom 231-Insider-P 1-Phase PumpSaver®Plus fits inside 1/3, 1/2, 3/4 and 1HP, 230V Franklin, Pentek or CentriPro control boxes. The Model 231-Insider-P is a pump monitor designed to protect single-phase pumps from dry-well, dead-head, jammed impeller, overvoltage and undervoltage conditions.

A calibration adjustment allows the Insider-P to be calibrated to specific pumping applications, thereby reducing the possibility of false or nuisance tripping. A unique microcontroller-based voltage and current-sensing algorithm constantly monitors the incoming power for fluctuations. When an abnormality, such as a loss of load is detected, the PumpSaver®Plus deactivates its output relay directly disconnecting 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 231-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. An IR Kit-12 (12” fiber optic kit) is included with each 231-Insider-P, allowing the Informer to access these parameters even when the 231-Insider-P is enclosed in a control box. This is valuable for troubleshooting the pump while it is running.
