Description

AQ-M215 offers a modular protection and control solution for larger and more important motors that require both current-based and voltage-based protection functions along with complete measurements. You can add up to three (3) I/O or communication cards into the device for more comprehensive monitoring and control applications. You can also connect up to sixteen (16) RTD signals for thermal alarming and tripping. AQ-M215 communicates using various protocols, including communication according to the IEC 61850 standard.

Highlights:

  • Powerful motor management.
  • Five (5) thermal models (time constant accurate).
  • Soft start protection beginning from 6 Hz.
  • Wye-delta started motor supervision.
  • Two-speed motor protection.
  • Optional power and energy measurement accuracy of up to 0.2 %.
