AQ-M210 Electric Motor Protection Devices

AQ-M210 Electric Motor Protection Devices

The AQ-M210 electric motor protection devices offer a modular protection and control solution for small and medium-sized 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.
