SubMonitor is designed to protect 3-phase pumps with horsepower ratings between 3 and 200 hp. Current, voltage and motor temperature are monitored using three integrated current transformers. A digital display provides current and voltage readings for all three legs and allows the user to set up the SubMonitor quickly and easily. The SubMonitor is the latest innovation in 3-phase pump protection from Franklin Electric. Using state-of-the-art technology, the SubMonitor provides the ultimate protection for a pump and motor. There is simply no better way to protect a large 3-phase submersible pump investment than with a SubMonitor. It is the protection device that can sense overheating straight from the motor windings! And it is made by the world leader in submersible motors – Franklin Electric.
