925 001 Surge arrester for KNX / EIB

Type: DEHN 925 001 Surge arrester for KNX / EIB

EAN: 4013364047365

Bus System: KNX (TP)

Mounting: Built-in installation

Surge arrester that is adapted to the KNX / EIB installation environment in terms of discharge capacity, protective effect and mechanics. Like the bus terminal, it can be plugged into the bus terminals of the terminal and connected using existing connecting cables. The arrester can also be connected to an existing bus terminal on the terminal. In particular, linear or flat connectors are protected, as well as gates and sensors on the external walls of buildings.

- Minimum space requirements in the design of the KNX / EIB bus terminal
- System tested with EIBA certification
