This is an automatic control box originally for 240V/50Hz single phase submersible pumps.
The controller automatically controls the pump motor as well as providing comprehensive pump protection and phase failure protection. It works in either auto or manual way
The box are metal casing, comes with 6 water probes. It is compatible with all 4-wires deep well pump in the market that required a capacitor to work.
Among these 6 probes, 3 are for monitoring the well's water level (up, mid and low) and the other 3 for monitoring the storage tank's water level. You can bypass either monitoring or both; to use as a manual control box when needed. With the automatic box installed, the pump will turn on and off automatically according to the water levels of both the tank and the well. This is extremely important when using it in a well with limited water supply, as the pump only should be operating when it submerse in the water to get enough cooling and lubricating by the water going through it.
The automatic control box has an auto/manual switch. When switch to “manual”. The control box will works like starter a box.
It can be installed at indoor or outdoor.

The 2HP single phase auto control box is a great product. It seems to be very well made and importantly for me, the door seal keeps the ants out.
