DEHN Protects Power Supply Networks

During the last 2 years, DEHN + SOEHNE have introduced a new generation of Surge protection devices providing the ultimate solution in power supply networks protection. This generation includes the new Modular combined DEHNvenCI Unit, the Dehnbloc maxi 1 CI series, the new Dehnguard CI series, and the new Dehnguard SE H LI series.

DEHNVentil CI unique Features includes:

• Integrated Backup Fuse inducing space saving in panel
• 100KA (10/350)
• Comply with TOV test requirement (440v / 120min L-N)
• Can be installed either in parallel or in series
• Visual indication and remote signaling unit even for N/PE arrester
The DEHNguard … CI series with integrated fuse combines short-circuit and surge protection in a single protection module resulting in space saving and setting new patterns for ease of application.
Also, DEHN+SOEHNE have introduced the new Dehnguard SE H LI class II arrester among with the new H LI series which is the first “intelligent” surge arrester using a pro-active thermo control to warn the user about upcoming failure of the surge protection system. The 3 stage visual indicator, coupled with a floating changeover contact for remote signaling,to protect installations which require maximum availability such as data centers, power plants or wind turbines against surges. Planned maintenance for type 2 surge protective devices can be easily and efficiently performed in all low-voltage installations.It’s the Green-Yellow-Red device.
