Product details
The signalling version of DEHN's eight-module three-phase TN combined arrester. It carries out the same Type 1 and Type 2 duties at the origin of the installation and adds monitoring contacts so the protection status is visible from wherever the site is supervised.
Key features
- Combined Type 1 and Type 2 protection for three-phase TN installations
- Monitoring contacts for remote signalling to BMS, SCADA or alarm panel
- Eight DIN modules, protecting all line conductors and the neutral path
- Pluggable protection modules for replacement without disturbing terminations
- Local status indication retained for on-site checks
Typical applications
Choose it for supervised intake panels in manufacturing and process plants, logistics and cold storage sites, data and telecoms facilities, utilities and water industry installations, and commercial buildings where the maintenance regime requires protective device status to be reported centrally.
Compliance
Combined Type 1 and Type 2 devices are classified under the BS EN 61643-11 series and are installed at the origin of the installation, coordinated with Type 2 protection downstream. BS 7671 requires transient overvoltage risk to be assessed and appropriate protection provided.
