Installation Sheet

The E280 concept is based on the use of plug-in module to protect telecom and data lines. The E280 line covers all multi-line telephone and data installation configurations: there is an E280 module and a suitable support for every type. Each module protects two pairs and is available for all types of line. The plug-in concept makes maintenance easy and lest you mix different types of line on the same support.
