DEHNcombo modular:
PV protection as a compact plug-in solution

Whether for residential buildings, commercial premises or solar parks – the Type 1 + 2 DEHNcombo modular combined arrester is our special solution for all types of photovoltaic systems. The new version with MP base part makes surge protection easier for you, from planning and installation to maintenance, thanks to push-in double terminals and a modular design.

In addition, the protective device can be expanded with STAK 4x10 pin-shaped terminals. These also offer convenient push-in connections and allow space-saving bundling of up to three DC strings directly at the surge protective device. Ideal for use in ground-mounted PV systems with central inverters.

Advantages for you

Modular and pluggable

For easy handling during installation and maintenance: The base part of all DEHNcombo models can remain on the DIN rail when inserting or replacing the plug-in protection modules.

Saves space and money

The compact design with only 3 standard DIN modules facilitates integration into the distribution cabinet. In conjunction with the STAK 4x10 push-in spring terminal, up to three strings can be grouped together directly at the protection device, meaning fewer individual components are needed and saving space and money.

Stable and low-maintenance

The push-in double terminals provide a permanently secure hold on the connected conductors, even when subjected to temperature fluctuations or other environmental influences – so no retightening is necessary, which reduces maintenance costs.
