Earth fault and short circuit indicator Electromechanics

Flexible error indicators with LCD and Modbus interface

The MD fault indicators are versatile earth fault and short-circuit indicators for radial networks and open ring networks in medium-voltage applications. They feature an LCD display, extensive setting options, and a serial Modbus interface. The sensors are connected via cable, are separable, and are ideal for retrofitting. Depending on the version, earth fault, short-circuit, or combined devices are available.

  • LCD display for error indication and display of operating current per phase
  • Fully configurable directly on the device or via Modbus (SCADA integration)
  • Adjustable response values for ground faults and short circuits, as well as automatic threshold value determination
  • Separate remote signaling of earth faults and short circuits via changeover contacts
  • Flexible power supply: battery, DC, or AC
