AQ-M210 Motor Protection IED

The AQ-M210 offers a modular motor protection and control solution for small and medium size
motors. Up to four optional I/O or communication cards are available for more comprehensive
monitoring and control applications.

Up to 12 RTD signals can be connected for thermal alarming and tripping. The AQ-M210
communicates using various protocols including IEC 61850 substation  communication standard.
