I am working with a 20hp water pump for which I need a circuit that cuts off the power supply when the current goes over a cutoff value. The maximum current is 30A.
The problem is that the value of current is also an important issue.
The pump keeps on functioning for a longer time if the current is only a bit greater than 30A but if the current is much larger than 30A, then the pump sustains itself for a comparatively shorter time.
Can anybody provide me with some text pertaining to this issue or the cutoff circuits...?
