Red/Line - Surge protection for power supply systems

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.
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.
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.
DEHNguard Wind

DEHNguard protects wind turbines

The integrated series connection of a varistor and a gas discharge tube prevents undesired tripping of the SPD in case of voltage peaks up to 2,200 Vpeak – A great benefit for the protection of wind turbines.
DEHN schützt Pipelines mit der robusten Abgrenzeinheit DASD

Decoupler DASD

Robust and powerful. Protect employees, limit overvoltages, prevent AC corrosion: The decoupler provides protection against transient, temporary and long-duration overvoltages.
