EMG Type LE earth fault sensor Product photo
Sensors for ground faults Electromechanics

Ground fault sensor type LE with fiber optic connection

The LE earth fault sensor is used for reliable detection of earth fault currents in medium-voltage networks. The connection to the display device is potential-free via an optical fiber cable, which ensures reliable signal transmission. The sensor is installed on shielded conductors and detects the total current via a multi-layer steel band that is placed around the three conductors of a cable. Thanks to its separable design, it can be easily retrofitted in existing systems. The response value can be conveniently adjusted using a rotary switch.

  • Potential-free signal transmission via optical fibers
  • Seven selectable response values from 10 A to 100 A
  • Total current measurement via multi-layer steel strip
  • Easy installation and retrofitting using cable ties
  • Fully encapsulated design with IP67 protection rating
