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.
