- Proprietary microcontroller based circuitry, constant monitoring of voltage and current protects pumps from dry well, dead head, jammed impeller, rapid cycling and voltage faults
- Onboard calibration adjustment, allows user to adjust the current sensitivity for the dry well/dead head trip point from 70% to 90% of the full load
- Adjustable restart delay, allows user to select well recovery time delay after a dry well condition occurs, or to select manual reset
- Built-in IR communications link, used with the Informer, allows user to see stored faults, run time and also troubleshoot the pump while it's running
- LED indication, provides status and diagnostics for troubleshooting
- 5 s overcurrent, 4 s dry well trip delay range
The Littelfuse® 235P is designed to protect 5 to 15 hp, 230 VAC, 1-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. The 235P communicates with a hand held diagnostics tool called the informer (sold separately). The informer displays parameters including calibration points, trip points, run time and last faults. An external current transformer is required for operation.
