Control Boxes

For remote pumping applications, all four model submersible pumps will require a control box (Figure 7).

For each model submersible pump there is an associated control box. Reference Table 4 for the desired control box and applicable heater. The heater size is determined by the the full load amps the pump will draw.

These water-resistant control boxes provide electronic overload protection a watertight enclosure and glands to prevent water from leaking into the box, and a float switch interface.
