IP protection class (EN60598)
The International Protection (or IP protection class) in electrical engineering is a code that summarises the protection level of an electrical device
against accidental or intentional contact with the human body or with objects, and protection against contact with water.
IK Code (EN62262)
IK Code is an international numeric classification for the degrees of protection provided by enclosures for electrical equipment against external
mechanical impacts, and specify the capacity of an enclosure to protect its contents from external impacts, measured in Joule.

Insulation class (EN60598)
Electrical insulation classes represent the homogeneous grouping defined by the IEC (International Electrotechnical Commission) of the technical
characteristics applicable to an electric device in order to limit the risk of electrocution resulting from a fault in said device.
Class III
Devices in this class do not have voltage values above the SELV (safety extra low voltage)
Class II
Devices in this class are designed in such a way that they do not need to be grounded
Class I
Devices in this class must have all their accessible parts grounded by way of an earth conductor.
