MPR 2000, MPC 2000
Digital Motor Protection Relay

The MPR 2000 monitors three phase & ground currents, voltages, and

temperature inputs to provide one of the most comprehensive motor

protectionpackages available. Wth up to 10 temperature sensors,

the MPR 2000 monitors as many as 39 programmable protective

functions. It is ideal for high voltage motors, large low voltage motors,

and applications where full protection and advanced warning is crucial,

such as in the process and chemical industries.

MPC 2000   Digital Motor Protection and Control Relay

Similar to the MPR 2000 except that it also incorporates advanced
control capabilities for all types of starting methods, including soft
starters and variable frequency drives.
The MPC 2000 has been specifically designed for integration into
motor management systems in chemical, petrochemical and other
process systems.
