Built-in Double Dimmer EDD-T42

The flush-mounted LED Double Dimmer EDD-T42 with central plate is a double dimmer for replacing series switches and for space-saving dimming of two light points. It is suitable for dimmable LED lamps, 230V incandescent lamps, halogen and low-voltage halogen lamps with magnetic transformer. For use in standard DIN 49073 flush-mount boxes with 60mm installation opening.

Quick Facts

  • replace series switch to double dimmer
  • dimming of 2 groups each 5-40W LED or 15-110VA (ohmic)

The dimmer is intended for installation in device sockets according to DIN 49073.

Power reduction of the maximum power indicated on the dimmer as a function of the ambient temperature:
The dimmer heats up during operation because a small part of the connected load is converted into heat. The specified nominal output is designed for installation of the dimmer in a solid stone wall. If the dimmer is installed in a wall made of gas concrete, wood, plasterboard or in a surface-mounted housing, the maximum connected load must be reduced by at least 20%. This reduction is also necessary if several dimmers are installed in a combination or if other heat sources lead to further heating.
