EXLIM R054-CN072
This surge arrester provides protection for switchgear, transformers and other equipment in high voltage systems against atmospheric and switching overvoltages.
Especially suitable for applications where:
– Requirements of lightning intensity, energy capability and pollution are moderate
The EXLIM R-C is an excellent choice when a porcelain housed surge arrester is required.

Each crate contains a certain number of arrester units and accessories for assembly and erection. A packing list is attached externally on each crate.
Each separate crate is numbered and the numbers of all crates and their contents are listed in the shipping specification.
Hitachi Energy reserves the right to pack arresters in the most effective/economic combination. Alternate or non-standard crates may
involve additional charges.
The table above is to be seen as an approximation and specific data for deliveries may differ from the values given.
