Our Motor Protection and Control Relay provides a comprehensive motor protection and control package. It is a new generation of microprocessor-based relay / controller designed to operate with a three-phase induction motors. Monitoring 3-phase currents and voltages together with 10 RTD/Thermistor temperature inputs it provides an ideal solution for Medium Voltage Motors.
True RMS voltages and currents are measured at a sampling rate of 0.5 ms, enables the SI-MPR3 to be used with electronic motor drives like soft starters.
