Description

Littelfuse 235P PumpSaver Plus Product Description

The Littelfuse 235P is designed to protect 5-15 hp, 230V, single-phase pumps from dry-well, dead-head, jammed impeller and overvoltage and undervoltage conditions. A calibration adjustment allows the 235P 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 causing overcurrent and undercurrent. When an abnormality, such as loss of suction is detected, the 235P deactivates its output relay and directly disconnects the pump motor.

Littelfuse 235P PumpSaver Plus Typical Application

  • Well Pump
  • Reservoir Pump
  • Transfer Pump
  • Sewage Pump
