Product details
A Type 2 arrester only protects you while its module is healthy, and on a PME board tucked inside a riser cupboard nobody is checking the window. This single-module DEHN device for TN-C-S installations carries monitoring contacts, so the board reports its own protection status back to whatever system is watching.
Key features
- Single-pole Type 2 protection for single-phase TN-C-S supplies, one module wide
- Monitoring contacts allow remote end-of-life signalling to BMS, PLC or alarm panel
- Pluggable protection module means replacement does not disturb the main terminations
- Local status indication retained alongside the remote contact
- Makes surge protection auditable on sites with a planned maintenance regime
Typical applications
Specify the signalling version for landlord and riser boards in apartment blocks, unattended plant rooms, telecoms and utility cabinets, EV charging infrastructure, and any PME-fed board on a site monitored from a remote head-end. A single spare digital input on the existing controller is usually all that is needed to bring the status back.
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 the risk from transient overvoltages to be assessed, with coordinated protection provided where the consequences justify it.
