  • Small footprint designed specifically for IEC and NEMA MCC applications
  • Integrated pushbuttons and LED indicators reduce external components and wiring
  • Flexible DIN rail mounting
  • Multiple communication protocols allows simple integration into monitoring and control systems
  • Optional control panel provides local control
Applications
  • Low Voltage three phase AC motors
  • MCC and standalone Panel Mount Applications
  • IEC and NEMA Motor Control Center (MCCs)
  • Process control applications
  • System architecture requiring multiple, simultaneous communications
  • FVNR, FVR, Two Speed motors

Protection and Control
The MM200 is a digital motor protection and control system, designed for Low Voltage motor applications. Compact and powerful, the MM200's protection can be scaled to the specific requirements of your system.

Motor Thermal Model
To provide optimal protection and maximize run time, the MM200 employs an advanced thermal model, consisting of four key elements:
  • Overload Curves
  • Unbalance Biasing
  • Hot/Cold Safe Stall Ratio
  • Hot/Cold Safe Stall Ratio
  • Motor Cooling Time Constants

Overload Curves
The MM200 thermal model can be programmed with one of 15 standard overload curves.When properly selected to match the motor manufactures thermal damage curves, the MM200 overload curve and Overload Pickup Level will determine the thermal capacity accumulated within the motor.

Monitoring and Metering
The MM200 includes high accuracy metering of current signals. Current parameters are available as total RMS magnitude.
  • Digital Counters - digital counters aid in system analysis and preventative maintenance
  • Motor Learned Data - critical tool to identifying changes in the operating characteristics of the system, motor and connected loads
  • Advanced Device Health - identify possible issues, improving system availability with comprehensive diagnostic testing performed at start-up and continuously during runtime

Communications
The MM200 utilizes the most advanced communications technologies available today making it an easier and more flexible motor protection relay to use and integrate into new and existing infrastructures. Multiple communication ports and protocols allow control and easy access to information from the MM200. All communication ports are capable of communication simultaneously.

Standard communication protocols include:
  • Modbus RTU
  • Fieldbus Protocol with dedicated port
    - DeviceNet or
    - Profibus DP

EnerVista™ Software
The MM200 utilizes the most advanced communications technologies available today making it an easier and more flexible motor protection relay to use and integrate into new and existing infrastructures. Multiple communication ports and protocols allow control and easy access to information from the MM200. All communication ports are capable of communication simultaneously.
