- Submonitor



Years of experience in designing and manufacturing our own motors mean that we also know how to protect them. Franklin’s single- and three-phase protective devices have been exclusively designed to help extend the life of Franklin motors. They monitor and diagnose motor load to prevent pump or motor failure due to adverse conditions such as low-flow wells, pump damage, clogging, bound pump, or power mishaps.

With Franklin Electric’s SubMonitor, you can protect against adverse conditions such as low-yielding wells, pump damage, clogging, bound pumps and power mishaps. SubMonitor is designed to protect three-phase motor and pump systems with 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. Data can be downloaded to a PC using Franklin’s D3 device.

SubMonitor protects against:

  • Under/Overload n False Start (Chattering) n Overheated Motor (Subtrol-equipped)
  • Under/Overvoltage n Current Unbalance n Phase Reversal
