Product details
Origin-of-installation protection is the part of a surge scheme least likely to be inspected, because the intake cupboard is rarely opened. This four-module combined Type 1 and 2 arrester for single-phase TN systems includes monitoring contacts, so the state of that first line of defence is reported rather than assumed.
Key features
- Combined Type 1 and Type 2 protection for single-phase TN installations
- Monitoring contacts for remote end-of-life signalling to BMS, alarm panel or telemetry
- Four DIN modules, mounting on standard 35mm rail at the intake position
- Pluggable protection modules for replacement without re-terminating conductors
- Local status indication retained for checks made at the board
Typical applications
Use it at intake positions on sites that are monitored remotely rather than staffed: telemetry and pumping stations, telecoms cabinets, unmanned industrial units, agricultural buildings with lightning protection, and single-phase supplies on exposed rural sites. The contact brings the SPD into the same reporting regime as the rest of the site plant.
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.
