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.
The new DEHNguard® SE DC type 2 surge arrester designed for use in d.c. circuits with the powerful d.c. switching DCD for voltages between 60 V and 900 V.
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.
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.
Type 1 lightning current arrester with integrated backup fuse - up to 60% less space in the switchgear cabinet than conventional solutions.
VCSD 40 IP65 limits long-term, temporary and transient overvoltages. The voltage-controlled short-circuiting device of the d.c. decoupler limits a.c. voltages to a preset value without negatively affecting the desired d.c. potential.
