GARO's Surge Protection Device (SPD) can be used in all types of power distribution facilities. It is designed for mounting on a DIN rail and fits under modular cover. Class C / II surge protection devices are specially developed for protection against overvoltage in low voltage systems. Most have replaceable protection modules and the housings are halogen-free. Manufactured from flame-resistant PBT or flame-resistant nylon (depending on the model). All terminals are made of copper; if connecting with aluminium, adapters must be used.
For overhead lines, we have a special protection device called GST.
Can be used on systems with and without distributed earth.
As of 1.1.2019, surge protection is a mandatory protection in the fuse box when installing a new electrical circuit for charging electric vehicles. This applies to both a new charging point or charging station.
We are required by the regulation on electrical equipment § 21 to inform our customers that all electrical material intended to be included in a permanent electrical installation can only be installed by an authorized and registered installation company.

Questions and Answers
Do I need surge protection?
NEK 400:2018, section 722 supply of electric vehicles says the following:
It is now required that the connection point should be protected by a surge protector. This can be a surge protector that is in front of the entire installation.
The reason is that the number of chargeable cars that have had their cars damaged as a result of lightning surges or connection surges is increasing rapidly. The cost of a repair can amount to several hundred thousand and it is not certain that this is covered by the insurance. It is recommended to interrupt and disconnect the charging equipment during thunderstorms.
