DEHN products
Here you will find an overview of the relevant products for a comprehensive surge protection concept for electromobility.
For protecting the power supply at the main feeder. Spark-gap-based combined arrester with integrated lightning current carrying backup fuse and low voltage protection level UP ≤ 1.5 kV (including backup fuse). Extinction of main follow currents up to 100 kArms.
Alternative: For protecting the power supply.
Type 2 surge arrester with integrated ACI switch/spark gap combination which allows safe dimensioning. Cross-sectional area of only 6mm² Cu is always sufficient.
Alternative: Type 2 arrester with integrated backup fuse in NH-00 design.
Our recommendation:
Combined lightning current and surge arrester to protect power supply systems in the charging infrastructure.
Time-proven spark gap technology for three-phase TT and TN-S systems (3+1 configuration). Type 1 + type 2 + type 3 protective effect up to the terminal device.
Alternative:
Type 1 and type 2 spark-gap-based combined arrester for three-phase TT and TN-S systems. To be snapped on 40 mm busbar systems.
Alternative: Type 2 arrester with integrated switch/spark gap combination. Can be used without additional backup fuse.
This compact type 2 and type 3 surge arrester meets all relevant standards and offers reliable protection. With its many different mounting options, it fits into almost any gap. Our recommendation for use in wall boxes.
Type 1 and type 2 combined arrester for DC current characteristic up to 950 V. With powerful DC switching device DCD.
Alternative:
Type 2 arrester for DC current characteristic up to 900 V. With powerful DC switching device DCD.
