The SubMonitor is Franklin Electric’s latest innovation in 3-phase pump protection, delivering advanced, state-of-the-art technology to safeguard your pump and motor investment. It’s the ultimate solution for protecting large 3-phase submersible pumps – including direct motor temperature monitoring from within the windings themselves. And it’s built by the global leader in submersible motor technology: Franklin Electric.

Engineered for 3-phase pumps with power ratings from 2.2 to 150 kW, the SubMonitor continuously monitors current, voltage and motor temperature via three integrated current transformers. A user-friendly digital display provides real-time current and voltage readings across all three phases, making setup and operation both quick and straightforward.
