CB12/CB14 Control Boxes

For remote pumping applications, both submersible pumps, require a control box (Figure 7).

The CB12 control box requires 230VAC, 3-phase input voltage for normal operation, while the CB14 control box requires 460VAC, 3-phase input voltage. Reference Table 3 for the desired 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 fl oat switch interface.
