DEHNpatch: protection for Ethernet infrastructure
The DEHNpatch surge arrester protects Ethernet applications up to 10 GBps and 4PPoE. This secures the flow of data even after surges or lightning strikes. Maximum performance with full protection: DEHNpatch is the surge protection all-rounder for structured cabling.
- Transmission performance 10 Gbps
- Status indication
- Approval for use in hazardous areas

Technical features at a glance
Protection for Ethernet infrastructure
Applications in the building
The DEHNpatch protects communication systems of building infrastructure (e.g. heating and ventilation) and the communication interfaces of fire alarm systems, IP cameras, PoE camera systems, access monitoring and control systems.
E-mobility
The DEHNpatch protects Ethernet interfaces of the charging infrastructure so that the charging electronics function reliably.
Process industry
The DEHNpatch protects Ethernet-based devices in potentially explosive atmospheres (e.g. IP cameras).
Wind turbines
The DEHNpatch protects the communication structure in the wind turbine. The option of remote diagnostics saves time and costs.
Railway technology
The DEHNpatch protects interlocking technology and signalling, control and telecommunications systems. The combined arrester with RJ45 connection system is used to maximise signal availability and minimise downtimes due to damaged or malfunctioning electrical systems.
Data distributors
The DEHNpatch protects structured cabling, patch rack systems, Ethernet switches and access points for smooth data and communication flow.
Industry
The surge arrester protects the Ethernet infrastructure and is an important component in our protection concepts for industrial production processes.
Data centre
The surge arrester protects the data flow in data centres and ensures that it is continued in the event of a surge or lightning strike.
