Product details
The signalling version of DEHN's four-module three-phase TN arrester. It does the same protective job at the distribution board, and adds a contact set so the control system knows the moment a module reaches the end of its life rather than at the next inspection.
Key features
- Type 2 protection for three-phase TN distribution boards, four modules wide
- Monitoring contacts for remote signalling into BMS, PLC, SCADA or an alarm panel
- Pluggable protection modules keep replacement clear of the field wiring
- Local indication retained for checks made at the board itself
- Meets specifications that require SPD status to be brought back to the control system
Typical applications
Specify it for switchrooms and plant rooms that are visited occasionally, data centre and comms sub-distribution, production and process panels under SCADA supervision, water industry and utility installations, and managed commercial estates where protection status has to be reported centrally rather than checked by eye.
Compliance
Type 2 devices are classified under the BS EN 61643-11 series and are fitted at distribution boards to limit switching and induced overvoltages. BS 7671 requires transient overvoltage risk to be assessed and protection provided where the consequences justify it.
