Microprocessor-controlled switchgear for level-dependent control of one, two or three submersible pumps with float switch for level measurement. The parametrization is carried out using dip switches and potentiometers.


1x…2x digital inputs* for float switch (pump on/off)

1x digital input for high water signal with float switch (high water alarm)

1x…2x inputs* for thermal winding monitoring with bimetallic temperature sensor. Connection of PTC sensors is not possible!


1x potential-free contact for the collective fault signal (SSM)

1x potential-free contact for the high water alarm (for switchgear for 2 pumps)

*Depending on the number of pumps that can be connected.
