Recommended products

E-Mobility - recommended products NSHV Ladesäule Datenseite Datenseite Ladesäule Datenseite Erdung, Potentialausgleich

A - Low-voltage main distribution board of smart transformer sub-stations

DEHNvenCI

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.

DEHNguard ACI

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.

VA NH00

Alternative: Type 2 arrester with integrated backup fuse in NH-00 design.

B - Charging post

AC-supplied charging posts

DEHNvap EMOB

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.

 

DEHNshield ZP

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.

DEHNguard ACI

Alternative: Type 2 arrester with integrated switch/spark gap combination. Can be used without additional backup fuse.

DC-supplied charging posts

DEHNguard ME DC

Type 1 and type 2 combined arrester for DC current characteristic up to 950 V. With powerful DC switching device DCD.

DEHNguard SE DC

Alternative:
Type 2 arrester for DC current characteristic up to 900 V. With powerful DC switching device DCD.
