DEHNcord R 3P type 2 arrester
Electric shutters and Venetian blinds should offer comfort and ease of use. Time-controlled, brightness-controlled or operated via mobile phone... "smart" shutters and blinds are often already standard. These sensitive electronics must be protected.
IEC 62305-3: According to the lightning protection zone concept, all lines entering the structure must be provided with a surge protective device.
IEC 60364-4-44/5-53: This device complies with the recommendation that all lines entering the structure must be protected. DEHNcord R even protects structures without external lighting protection system against surges.
Equipotential bonding in conformity with the lightning protection zone concept – Carried out properly
The multipole DEHNcord R 3P type 2 surge arrester features a monitoring device and a disconnector. By installing this device, the requirements of the lightning protection zone concept and the IEC 60364-4-44/5-53 installation standard for buildings are met.
Easy and safe installation
DEHNcord R 3P is mounted as an adapter directly into the connecting cable of the motor. All electrical connections are now protected by a single device where formerly two single-phase protective devices were required. Protection of the "up" and "down" phase and the neutral conductor are already integrated. This saves installation time.
Another installation benefit: The device is directly mounted in the shutter/blind box without tools by means of a conventional Hirschmann connector (STAK3/STAS3).
