There are nine different models in the new TPMP Series three-phase motor protector line. Users can choose protection from phase sequence problems to phase loss and out-of-balance issues, the manufacturer states. All of the models disconnect the motor pilot circuit when the monitored problem is detected and will only re-energize the circuit when all three phases are activated at the full voltage rates, the company says. Six models also offer a 10-second delay.
