Mains Filter

NF 10

  • Protection of sensitive industrial electronics equipment against balanced and unbalanced high-frequency interference
  • For use in combination with surge protective devices, e.g. DEHNrail M 2P 255
  • Easy installation on DIN rails in switchgear cabinets

Details

The NF 10 mains filter ideally complements surge protective devices for industrial terminal equipment. This DIN rail mounted device is perfectly suited for installation downstream of surge protective devices (e.g. DEHNrail M 2P 255). In addition to surge protection, protection against balanced and unbalanced high-frequency interference is provided. The separate input and output terminals of the mains filter ensure optimal protection of the equipment to be protected. Apart from surge protection, the mains filter also fulfils electromagnetic compatibility requirements in plant and control systems.
