SPP provided

It protect motor from phase failure. In 3 phase motor. Out of 3 phase if any phase failed then motor run in 2 phase and motor winding gets burn.

It protect motor from phase interchange. Out of 3 phase if any phase changed, then motor rotate reverse in this case motor winding gets burn

It protect motor from voltage different between 3 phase, Voltage between 3 phase must be same

Working :

This model has dry run protection so it only starts the motor if water is present in the underground tank or sump.

It has current based dry running. If the motor runs without water then it takes a lower ampere (current) then its actual current. so when the motor current is down from actual current, it stops the motor and protects the motor from dry running. 

Protect motor from dry running.
