What it actually does

This module is used to:

• Continuously monitor motor current (RMS sensing)
• Detect abnormal conditions:
  • overload (overcurrent over time)

  • imbalance
  • ground fault (depending configuration)
• Trip the contactor coil circuit to stop the motor
• Provide diagnostic feedback to PLC / control system
