Earth fault indicator Electromechanics

Simple and reliable earth fault detection with the EFL series

The EFL earth fault indicator is a cost-effective solution for reliable earth fault detection in radial networks and open ring networks with rigid or low-resistance earthing. Different device versions allow the indicator to be tailored to the specific application and available budget. The separable earth fault sensor allows for easy retrofitting. Power is supplied by a lithium battery, supplemented by a 230 V AC reset input for automatic reset when mains voltage returns.

  • Cost-effective earth fault indicator with graduated function variants
  • Suitable for beam and open ring nets
  • Divisible earth fault sensor type SE for retrofitting
  • LED indicator for permanent ground faults
  • Automatic reset possible via 230 V AC
