Product details
An intake arrester that has reached the end of its life leaves the whole installation exposed, and on an industrial site nobody is opening the main panel to check. This eight-module combined Type 1 and 2 device for three-phase TT and TN systems adds monitoring contacts so the condition is reported.
Key features
- Combined Type 1 and Type 2 protection for three-phase TT and TN installations
- Monitoring contacts for remote signalling into BMS, SCADA or an alarm panel
- Eight DIN modules covering three line poles plus the neutral path
- Pluggable protection modules replaced individually, wiring left in place
- Local status indication retained for inspection at the panel
Typical applications
Specify it for main intake panels on monitored industrial and infrastructure sites: manufacturing plants, distribution centres, water and wastewater works, data and telecoms facilities, and agricultural or renewable energy installations with an external lightning protection system. The contact feeds the site's existing alarm or SCADA reporting.
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.
