MCH

MCH-RDSI is the series of devices for discharging transient overvoltages induced in ISDN telephone lines, within the MCH range. In accordance with IEC 61643-21. In-line format.

  • Suitable for the protection of communications equipment connected to ISDN lines. By their nature, they are highly exposed to induced transient overvoltages (surges) associated with meteorological activity.
  • Protection of two telephone pairs.
  • Discharge capacity with an 8/20 μs waveform: 10 kA.
  • No installation required. It connects directly to the equipment to be protected via RJ45 connectors.
  • The MCH range also provides models for the protection of ADSL and PP lines.
