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 0_B–1 and higher
