Protection class

With a lamp, the protection class indicates which protective measures are necessary for an electrical blow. These must therefore always be specified on the equipment and are not with the IP Type of protection to confuse against foreign bodies and water. In Germany there are three different protective classes, e.g. B. A lamp with protection class II has increased and double insulation between the network circuit and the output voltage or the metal housing.

Here is an overview of all three protective classes:

Protection class I:
The first protection class stands for a protection, whereby all conductive housing parts of the lamp or the electrical device are connected to the so -called protective conductor system of the solid electrical installation. In the event of an error current, a backup is activated, which switches the circuit without tension.

Protection class II:
In the second protection class there is a reinforced or double insulation between the network circuit and the conductive housing of the lamp, which is called protective insulation. So is one lighting Protected with protection class II even if it would consist of an electrically conductive material.

Protection class III:
The third protection class is characterized by a so -called Protective tension from, whereby the devices marked with it with a Tension From a maximum of 50 volt Alternating current or 120 volt DC voltage. As in protection class II, you also need reinforced or double insulation between the network circuit and the output voltage. In addition, these luminaires need a safety transformer according to DIN EN 61558-2-6, which can only be dispensed with for protective small tension from batteries or batteries.
