Control boxes for single-phase 4" borehole motors - matched to each motor size

Every single-phase Stairs 4" borehole motor runs through a control box matched to its size. The run capacitor, overload protection and on/off switch come together in one unit, and larger motors add a start capacitor and relay. We supply the control box with the pump, motor and submersible cable as a matched set, ready to install. Tell us the motor size and we'll match the box.
