- Especially Adapted for 400V TN-grid
- Surge Protection Type 2 (intermediate protection)
- Installs on a DIN-Rail
- Especially developed against overvoltage in low voltage systems
Surge protection (etc.) from CENTECH can be used in all types of installations for the distribution of power. It is intended for mounting on a DIN- Rail and fits under a modular cover. Type 2 surge protector is especially developed for protection against overvoltage in low-voltage systems. Most have replaceable protection modules. Enclosures are halogen-free. Manufactured from flame retardant PBT or fire resistant nylon (depending on the model). All terminals are made of copper, if it should be connected with aluminum, transitions must be used.
The surge protector is supplied with a signal contact. This is for indicating the internal fuse within the surge protector.
Can be used on installations with or without distributed soil.
From 1 January 2019, a surge protector is a legally required protection in the fuse box when installing a new current course to the charging of electrical vehicles. This applies both to a new charging point or charging station.
According to regulations on electrical equipment §21, we are obliged to inform our customers that all electrical equipment intended to be part of a fixed electrical installation can only be installed by authorized and registered installation company installasjonsvirksomhet.

Questions and Answers
Do I have to have surge protection?
NEK 400:2018, part standard 722 supply of electrical vehicles states the following:
It is now required that the protection point must be protected by a surge protector. This can preferably be a surge protector that stands in front of the entire installation.
The reason being is that there is a greater increase in the number of rechargeable cars that have been destroyed as a result of lightning surges or connection surges. The repair costs can reach several hundred thousand kroner and it is not certain that this is covered by insurance. It is recommended to interrupt and disconnect the charging equipment during thunderstorms.
