Franklin Fueling Systems is pleased to announce the release of an upgraded Three-Phase Control Box for use with High Capacity Submersible Turbine Pumps. The STP-CB 3/5 control box’s updated design features a new, adjustable overload block. The new overload block eliminates the need for specific configurations of overload heaters for each high capacity pump model. The new control boxes will come preset from the factory with the same overload block settings as the previous model numbers; however, part numbers have changed as follows. The outer enclosure and list price remain unchanged, providing the same functionality and connectivity as did the previous version of the control box. As Franklin transitions to this new design, replacement overload heaters for use with the previous design of STP-CB 3/5 control boxes will continue to be offered while supplies last. Please contact Franklin Fueling Systems Customer Service at +1-608-838-8786 if you have any questions regarding the updated design.
