Replaced by MPS Motor Protection System. The PGR-6300 Motor Protection System monitors voltage, current, and temperature to provide a comprehensive package of 22 protective functions for motor protection. The Motor Protection System is a modular system with integrated protection, motor control, metering, and datalogging functions. Motor starter control functionality is programmable for all common starter types.
