Motor Protection–Advanced
MPS SERIES (PGR-6300)
Motor Protection System
Description
The MPS Motor Protection System monitors voltage, current,
and temperature to provide a comprehensive package of
22 protective functions.The MPS is a modular system with
integrated protection, motor control, metering, and data-logging
functions.This system is typically used to provide protection for
three-phase low- and medium-voltage, medium-
to high-horsepower induction motors.
