Protection relay for motor protection and control provides a comprehensive protection and control package. It is a new generation microprocessor-based relay/controller designed for use with 3-phase induction motors. Monitoring 3-phase currents and voltages along with 10 RTD/thermistor temperature inputs provides an ideal solution for medium-voltage motors.
TrueRMS values of voltages and currents are measured at a sampling rate of 0.5 ms, making the SI-MPR3 suitable for use with electronic motor drives such as soft-starts.
