Surge protection for wall boxes

Whether it's in your own garage, at work or at the supermarket: wallboxes are welcome. Not only do they make a substantial contribution to the expansion of the charging infrastructure, they also take up little space and blend discreetly into the appearance of the building. It is therefore all the more important to protect their permanent availability and enable uninterrupted charging. Overvoltages in particular, for example caused by lightning strikes in the vicinity, pose a risk to the function of the wallbox and the connected vehicle. Standards such as IEC 60364-4-44, section -443, and IEC 60364-5-54, section -534, therefore regulate the use of overvoltage protection measures.

Due to the compact design of wallboxes, the installation of protective devices is often challenging and complicated in practice – for manufacturers of charging equipment as well as for planning engineers and installers. The solution? Our compact surge arresters, specially developed for confined installation situations. Find out here what you need to consider when integrating standard-compliant surge protection and how our solutions can be installed even in the smallest of spaces.
