Motor Protection – Advanced (PGR 6000 Family)
PGR-6300 SERIES
Motor Protection System
Description
The PGR-6300 Motor Protection System monitors voltage,
current, and temperature (optional) to provide a comprehensive
package of 22 protective functions. The PGR-6300 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-
