BUStector

Surge Arrester

Surge arrester for KNX / EIB buses
Extremely space-saving due to KNX / EIB bus terminal design
System-tested with EIBA certification

Description

The discharge capacity, protective effect and mechanical design of BUStector surge arresters are adapted to the installation environment of KNX / EIB buses. Like a bus terminal, they can be plugged onto the bus terminal pins of a terminal device and can be connected by means of the existing connecting cables. BUStector surge arresters can also be connected to an existing bus terminal on the terminal device. They particularly protect line and area couplers as well as gateways and sensors installed at the outer walls of buildings.

Detail 1

Protection of a KNX power supply unit by means of a BUStector surge arrester mounted in the bus terminal slot.

Detail 2

Protection of a KNX bus coupling unit by means of a BUStector surge arrester mounted on a bus terminal in the mounting panel of a cable duct.
