AQ-M210 Motor protection IED

The AQ-M210 motor protection IED offers a modular protection and control solution for small and medium size motors. You can add up to four (4) I/O or communication cards into the device for more comprehensive
monitoring and control applications. You can also connect up to twelve (12) RTD signals for thermal alarming and tripping. AQ-M210 communicates using various protocols, including the IEC 61850 substation
communication standard.

 

Highlights

  • Five (5) thermal models (time constant accurate)
