EDF and ESF-G cabinets integrate LED bar level indication, motor protection, an AC contactor and a circuit breaker in a metal enclosure. The PCB control system supports automatic filling, drainage and upper/lower tank linkage, with water-shortage and overflow protection. Optional level-transmitter integration and alarm functions support system monitoring.
Use EDF models for single-phase water supply and drainage installations, and select the corresponding ESF models for three-phase systems. Typical applications include water towers, wells, storage tanks, irrigation, garage drainage and industrial water handling.
| Family | Models | Supply |
|---|---|---|
| EDF | EDF1302G, EDF1303G, EDF1305G | Single-phase 220V |
| ESF-G / ESF-GD | ESF-1303G, ESF-1305G, ESF-1310G, ESF-1303GD, ESF-1305GD, ESF-1310GD | Three-phase 380V |
Select the complete model for the pump and required control arrangement. Confirm the selected unit's motor-load rating and fitted protection components; the numeric model suffix alone is not a substitute for its electrical rating.

The front selector provides manual, stop and automatic modes, with separate power and operation indicators. In manual mode, the load runs independently of the level controller's internal setpoints. In automatic mode, the controller switches according to the configured high and low liquid levels.
Set the operating mode for the required filling, drainage or linked-tank duty, and verify the level signals and pump response during commissioning. The front display supports local level observation while the contactor controls the pump circuit.
