Surge Arrester

Surface-mounted surge protective device for telecommunications systems Quick installation due to plug-in terminals Different interface-specific types

Description

The surface-mounted surge arresters with a modern design particularly protect modems and telephone systems with RJ plugs. The plug-in terminals allow easy installation.

Detail 1

Easy and fast installation by means of RJ plug-in system.

Detail 2

DLI ISDN I and DLI TC 2 I devices feature an LED display that indicates the supply voltage..

Detail 3

DLI ISDN I is capable of protecting two terminal devices at the same time.

Detail 4

Fixing lugs on the enclosure allow easy and fast wall mounting.
