Intelligent motor protection and control device
( ECM801 )


 

Description

ECM801 Intelligent Motor Protection and Control Device is designed on the basis of ECM800. It is applied to 3-phase AC asynchronous motors (380V or 660V).
This intelligent device can replace many decentralized units such as contactors, circuit breakers etc. Besides, its pluggable terminals and standard DIN rail installation saves wiring material usage and reduces cabling complexity and time.
With advanced motor protection, control automation, communication and diagnostics, ECM801 will be the best device for protecting your motors.

Feature

  • Integrates measurement, protection, control and communication
  • Unique separation design, CTs are separated from main module.
  • Provides 9 types of standard functions and 8 types of optional protection functions
  • Provides 10 types of motor starting mode
  • Statistic data from the motors, failure logging
  • LED indicators in main module
  • Optional panel for local operation
  • Pluggable terminals, easy to install and maintain
  • Reliable electromagnetic compatibility
  • 35mm DIN rail mounting
