Output : R (Phase), Y (Phase), B (Phase) (motor or pump connections) 

Auto Switch Provided

Auto switch timer provided (when power goes and comes it will start with preset time,) timer adjustable

Auto Bypass Switch provided. (In Auto mode motor automatically start when power goes and comes and in manual mode motor start by pressing start and stop button)

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

Micro controller based design 

Digital Volt and ampere meter are provided to see system voltage and load current accordingly.

Two seperate display for volt and amp.

high voltage protection, 

low voltage protection,

Adjustable voltage limit (High and low both voltage protection limit adjustable)

overload protection

Adjustable overload from 0 to 30 A

Current based dry run protection provided 

Adjustable dry run current from 0 to 30 A

Voltage and Current calibration facility 

Short circuit protection

protection bypass facility 

Cyclic timer provided with bypass facility (adjusatble from 0 second to 999 min) If user want start and stop the motor on perticuler time then user can set the on and off time of cyclic timer 

Delay off timer provided with bypass facility (adjusatble from 0 second to 999 min) If user want to stop the motor after certain time then they can set the delay off timer. in this timing mode user can start the motor by pressing start button and it will auto stop based on preset delay off time.

On delay timer and off delay time provided (adjusatble from 0 second to 999 min) If user want to start the motor after certian time then they can use this timer.

High quality ABS Enclosure.

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.
