Control Boxes
Control boxes (Figure 3) are available for remote control and
thermal shut-down capability for the submersible pump. These
water resistant control boxes provide electronic overload
protection, watertight housing and glands to prevent water from
leaking into the box, and a float switch interface.
There are various control box models to choose from, reference
Table 2 for the model that meets your pumping requirements.
Contact Multiquip sales department to order control boxes as
listed in Table 2.
