Red/Line - Surge protection for power supply systems

DEHN protège les systèmes PV

DEHNcombo YPV

Protects PV systems from lightning and surge damage. It’s suitable for earthed (earthing of DC+ or DC-) and floating systems and can be used up to 10 kA without additional backup fuse.
DEHNguard ME DC Y 950 FM

DEHNguard ME DC Y 950 FM

Protects direct current applications up to 950 V. With DCD technology - in the event of an overload, the DC disconnector safely disconnects the protective device.
ACI

DEHNguard ACI

The switch-spark gap combination in type 2 arrester DEHNguard ACI makes upstream fuses superfluous. As a backup fuse is no longer required, you save time, space and material.
Anwendung ACI

Up to 400/690 V: DEHNguard SE CI 440

For industrial applications with a rated voltage of 400/690 V. Overvoltage protection and backup fuse combined in a single device. This saves space in the switchgear cabinet. Available in 2 versions: Industry and wind turbines.
DEHNshield ZP

DEHNshield ZP protects meters and terminal devices

This combined arrester is designed for 40 mm busbars. It is attached without tools by simply snapping it on. The spark gap technology with zero leakage current protects meters and terminal devices.
Poltet dg

DEHNguard M YPV

Type 2 arrester for the DC side. Protects PV system components like inverters and PV modules against overvoltage. Available in 2 versions: ≤ 1170 V and ≤ 1500 V.
DEHNcord

DEHNcord 3P with disconnection function

Small and compact arrester - with full performance! Ideally suited for LED mast lights and wherever an optimal protection solution for restricted space conditions is required.
dehnshield-1200 mit Fernmeldekontakt

DEHNshield with remote signalling contact

The proven space-saving combined arrester DEHNshield is now also available with a floating remote signalling contact. This allows an easy integration and monitoring through your factory master control system.
integrated-short-circuiting-device-vcsd

Voltage-controlled decoupling device VCSD

VCSD 40 IP65 limits long-term, temporary and transient overvoltages. The voltage-controlled short-circuiting device of the decoupling device limits AC voltages to a preset value without negatively affecting the desired DC potential.
dehncord-r-3p-portlet

Surge protection for electric shadings

DEHNcord R 3P: Type 2 arrester in the form of an adapter which is mounted into the connecting cable of the motor of a shutter controller/Venetian blind.
