Complectation

Insulation monitoring unit IMU-1200 is designed for operation as part of the factory-assembled distribution device and perform functions of measurement, protection, control, emergency shutdown of switching device (vacuum circuit breaker, contactor), signaling and indication of connection status in the power supply networks with isolated neutral.

IMU provides the following protection types

  • protection against earth leakage currents (insulation monitoring unit IMU);
  • maximal voltage protection (maxVP);
  • minimum voltage protection (minVP)
  • and phase-failure protection (PFP).
