Field detector DEF-01

  • Reacts to a constant magnetic field, HF electromagnetic field, interference from periodic discharges
  • Compatible with all electricity meters
  • Installation on a DIN-rail together with the metering device
Детектор поля DEF-01


DEF-01 – simple and reliable protection against theft of electricity by remote exposure to the meter with electromagnetic waves.

The principle of operation is to determine the fact of impact on the device and issue a command to disconnect consumer from the network.

The trip command is sent to the circuit breaker release or contactor.

Thus the device prevents consumption of the electric power in case of impact on the meter.
