DEHNshield

The DEHNshield combines powerful Type 1 + Type 2 surge protection with compact, spark-gap-based technology. Designed especially for residential buildings and applications with limited installation space, it provides reliable lightning equipotential bonding and protection of terminal equipment in a single device.

  • Type 1 + Type 2 combined arrester
  • Spark-gap-based technology
  • Compact, space-saving design

Technical Details

What sets the DEHNshield apart

  • Compact protection

    DEHNshield combines lightning equipotential bonding and surge protection in a compact design. With a width of only one standard DIN module per pole, it is particularly suitable for installations where space is limited.

    Save valuable space
    In systems with fuse protection up to 160 A, no additional backup fuse is required, making installation even more compact.

  • Powerful protection

    Spark-gap technology with the Wave Breaker Function reduces the energy from a lightning event downstream of the protective device to a minimum.

    Protect terminal devices
    This significantly reduces the energy load on terminal equipment and helps prevent negative interaction with the electrical installation.

  • Easy monitoring

    The integrated operating state and fault indication makes the status of the arrester easy to check at a glance. DEHNshield versions with remote signalling contact also allow convenient remote monitoring.

    Reliable status information
    The green/red inspection window provides a clear visual indication of the operating state.

Reliable protection for residential buildings

DEHNshield is an ideal solution for residential buildings and other applications requiring reliable lightning and surge protection. Its compact design makes it particularly suitable for installations with limited space, while spark-gap technology provides powerful protection for sensitive electrical equipment. DEHNshield can also be installed upstream of the meter in accordance with the applicable requirements.

Spark gap technology for comprehensive protection

DEHNshield uses spark-gap technology to combine lightning equipotential bonding and protection of terminal equipment in a single device. The integrated Wave Breaker Function reduces the impulse time and minimises the energy load on downstream equipment. This provides effective protection while preventing unwanted interaction with the electrical installation.
