How many joules of surge protection does Germany insert?

German electrical system standard stipulates the minimum protection level of surge protection, and the standard stipulates that electrical equipment needs to be protected to 1000V and 16A current. According to relevant standards, the protection level of surge protection of German plug-ins is the lowest level 3, that is, it needs to resist voltage surge of 1500V and the protection current should reach 2500A. Therefore, the minimum protection value of surge protection of German plug-ins should be 1500V/2500A=600 Joules. It should be noted that the specific protection needs to be comprehensively considered according to the relationship between actual use and product technical characteristics, and there may be different surge protection levels and requirements. If you have a specific German plug-in or device specification, please check the relevant instructions or consult the manufacturer for more details.
