LSA-A-LEI

Project Description

LSA-A-LEI


Description

SPD block for ten pairs with three-pole gas discharge tubes for telecommunications distribution systems, the LSA surge voltage components offer rapid, adequate protection. The LSA system offers both basic protection modules and fine protection modules to protect up to ten three-core wires per connection strip. Thus it can be immediately identified whether an arrester has to be replaced.

  • SPD block for ten pairs with three-pole gas discharge tubes
  • Bandwidth-optimised for secure transmission
  • For installation in conformity with the lightning protection zone concept at the boundaries from 0B–1 and higher
