DM2

DM2 is the range of combined devices for discharging induced transient overvoltages (Type 2 / Class II), and also provides fine protection for sensitive equipment (Type 3 / Class III) in accordance with IEC 61643-11. Complete with a built-in EMI filter. DIN rail monobloc format.

  • Suitable as the final stage of protection in installations with electromagnetic disturbances which might interrupt, degrade of limit system performance.
  • Series connection for applications up to 20 A rated current.
  • With electromagnetic interference (EMI) filter. Common mode attenuation of the filter is up to 82 dB.
  • Maximum discharge current with an 8/20 μs waveform. Imax: 20 kA.
  • Combined voltage pulse with 1.2/50 μs waveform. Uoc: 6 kV.
  • Single-phase 120 V and 230 V networks.
  • Remote and visual indication of life status of the protection device.
