Protection classes
These classes provide information on a luminaire’s stability in withstanding the penetration of dust,
solid foreign bodies and water in accordance with IEC / EN 60598 (VDE 0711).
The relevant protection class IP (International Protection) is marked on the luminaire in accordance
with the IEC 529 coding system.

Safety classes
Safety class I designates luminaires with an earth connection. In the event of a fault, the power
supply is switched off by overload/residual current protective devices.
Safety class II designates luminaires that have not only functional insulation but also additional
protective insulation. Under fault conditions, no dangerous voltage can reach metal parts which
can be touched. Many safety class I luminaires are also available in safety class II. Please contact us.
Safety class III indicates luminaires for safety extra-low voltage.
They can be connected only to safety transformers in accordance with EN 61558 / VDE 0570,
EN 61347 / VDE 712 or VDE 0100 Part 410. The transformer must be approved for this type of
installation.
