Product number: MRI3I1HE1D.


The digitial multifunctional relay MRI3-IHE has been designed as a universal time overcurrent protection relay with evaluation of the 2nd harmonic for transformers.

The relay gives a complete thermal characteristic of the electrical equipment to be protected taking into account its initial load.

The MRI3-IHE furthermore provides a universal time-overcurrent and earth fault protection with the following functions:

  • Two-step overload protection with evaluation of the 2nd harmonic,

  • Display of the measured values for 1st and 2nd harmonic,

  • independent (Definite) time overcurrent relay,

  • inverse time overcurrent relay with selectable characteristics,

  • two-element (low and high set) earth fault protection with definite or inverse time characteristics.

  • 19“ racks – fully withdrawable

  • Door mounting – withdrawable and sealable

  • Panel mounting – fully withdrawable

  • Fault / disturbance recorder

  • Intuitive HMI

  • Display (of primary values)

  • Easy setting software – Smart view

  • Compact form factor

  • Interconnection of renewable energies (DER – distributed energy resources) to the public grid.

  • Protection of High, Medium and Low Voltage feeders against thermal damages by overload or short circuit currents.
