Product details
A combined lightning current and surge arrester at the intake is an expensive item to replace wholesale, and it does not need to be. This DEHN line (L) protection module plugs into the installed base part and restores the line pole of a single-phase Type 1 and 2 arrester to full duty.
Key features
- Line (L) replacement module for DEHN combined Type 1 and 2 arresters
- Plug-in fit to the existing base part - incoming tails stay terminated
- Restores the spark-gap line path after an end-of-life indication
- Individual pole replacement rather than changing the whole arrester
- Sensible spare where the arrester protects an origin-of-installation position
Typical applications
Type 1 arresters sit at intake positions on buildings with lightning protection systems, overhead supplies and exposed rural or industrial sites, so a failure there leaves the whole installation without its first line of defence. Holding the line module as a spare lets facilities and maintenance teams clear a red indication at the next available shutdown rather than waiting on a lead time.
Compliance
Combined Type 1 and Type 2 devices are classified under the BS EN 61643-11 series. Replacement modules must match the base part and the system voltage the arrester was supplied for - fit only the module specified for your device.
