Product Description

Single pump control panel L 531
Application: Control & protect three phase pump, DOL

Model L531 is useful in all cases we need to control and protect single pump managing its turn-on and turn-off by different electric installations.
Our special design makes it a very reliable and sensitive protection against pump dry running without installation of any probe/sensor in the deep well.
