The Subtrol-Plus system is specifically designed to protect Franklin Electric six- and eight-inch three-phase submersible motors. Its microprocessor technology creates a system that detects overload, underload, overheating and rapid cycling and that shuts down the motor and provides a display of the condition when any of these faults occur. Each kit contains a Subtrol-Plus receiver, fuse block, suppressor module, sensor coils and lightning arrestor. Additional features include field-adjustable trip settings, automatic restart and external alarm/back-up system connection. Franklin Electric
