Integrated overload, short-circuit and overtemperature protection. The dimming actuator should not be on the same phase line as inductive loads (shutter motor, toroidal transformer, fluorescent tubes, etc.) - this could damage the dimmer! Only install and connect when voltage-free!
Dimming Specifications
After switching on, the dimmer automatically adjusts to a brightness of 20% if the connected light source was dimmed below this threshold before switching off. If the dimming level was above 20% before switching off, the same dimming level is output when switching on again.
