Control and protection units for one, two or three electrical pumps (versions for 4 or more electric pumps can available on request). Manual or automatic operation modes using a pressure switch or float switch. Besides In addition, there are two clamps for connecting the float relay minimum level or minimum pressure switch for protection against dry running. When triggered, the electric pump stops with indication by means of corresponding indicators on the block management. Control units protect motors against overload and phase mismatch. Signals about any triggered protections go directly to the control unit, as well as to remote points using "dry" contacts (if a remote control unit is connected management). Overload and phase misalignment protection automatically resets three times, on the fourth actuation it resets performed manually (any first three triggers are reset one hour after the last activation).
