Key Features & Typical Use
The Combination That Was Previously Missing
To get good options for fast charging, a French standard property has to choose between using a different socket shape, using an adaptor, or being unable to charge fast. The SD3B-021 comes with a type E socket face, which includes an earth pin inside the socket body.
Tiering a French Standard Property
Organizations having various locations differentiate their rooms based on their specifications and charging speed proves to be a very simple way to do so. Since equipments having both standard and fast charging models share the same cabinets, panel and frame, you can create tiers for the room without introducing a new range of products.
Serviced Apartments and Longer Stays
As the length of stay of guests increases, so does the number of gadgets they travel with and their expectations for places to feel like home. Fast charging units both in the extremely accessible places such as next to the bed and the work desk are features often noted in reviews. They can be perceived by guests regardless of their skill in handling the latest technology.
Consistent with the Whole Device Schedule
The module makes use of its 86 x 76mm panel identical to the French plug, switches, data ports, and its enclosed versions so that a building can maintain one plate style while at the same changing its function due to its placement among the devices which is the key element in the aesthetic coherence in large installations.

SD3B-021 – Fast Charging for Properties Specified to the French Standard
In our days, sockets are mostly used in German version, however, they are very uncommon as far as French version is concerned. Thus, there are some problems in regard to consistency and standards in the terms of repeatability. So let’s consider SD3B-021, which is a Type E socket with 20 W power output included into the same module with other devices of the building interior.
The determination is quite straightforward for an operator; the tier must be chosen according to the type of room, whereby maintaining panel type and installation method is a must. Since both the normal French socket (SD3B-017) and the two versions for charging (SD3B-019 and SD3B-023) use identical panels, there are no difficulties in case a combination of some functions in one room needs to be provided.
