Product details
Same duty as the standard two-module TN arrester, with one important addition: a set of monitoring contacts. Where a board is locked, remote or simply never opened, the contact is what turns an expired protection module from an unknown into a logged alarm.
Key features
- Type 2 protection for single-phase TN distribution boards, two modules wide
- Monitoring contacts wire back to a BMS, PLC, telemetry outstation or panel lamp
- Pluggable protection modules for replacement without re-terminating conductors
- Local status indication retained for hands-on inspection
- Supports maintenance regimes that need protection status to be reported, not assumed
Typical applications
Choose the signalling variant for landlord and riser boards, unmanned plant rooms, data and comms rooms, water and wastewater sites, telecom cabinets and multi-site estates run from a central monitoring platform. It is also the sensible option in panels built to a specification that calls for SPD status indication at the control system.
Compliance
Type 2 devices are classified under the BS EN 61643-11 series and are installed at distribution boards to limit switching and induced overvoltages. BS 7671 requires the risk from transient overvoltages to be assessed, with protection provided where the consequences justify it.
