Submersible pump controller, 3-level flood sensor, overvoltage protection, overcurrent protection, automatic drive control PZM-40 EXT10000317

The submersible pump controller measures the liquid level in the well using 3 immersion probes (not included in the set, SZH-01 probes are recommended) and an additional float placed in the expansion tank. Then, based on the collected information, the controller starts the pump, filling the tank. The device has a complete set of protections: over and under voltage, over and under current, auto reset function and a built-in 30A contactor.
