Spelsberg – Power and Internet available quickly – Spelsberg introduces socket distributors with LAN connection


Spelsberg has expanded its product range of socket distributors and housings with two models that enable LAN cables to be connected.


With the versions STV 1224-K-LAN and STV 922-K-LAN, which have side-mounted data sockets, both power and network cables can be connected quickly and clearly. The new socket distributors ensure a stable internet connection and simplify everyday processes as well as maintenance and repair work.

The socket combinations from Spelsberg open up quick and uncomplicated connection options – with the new design variants STV 1224-K-LAN and STV 922-K-LAN for both power and network cables. Disconnections, for example due to unstable WLAN connections, are a thing of the past.


Easy connection of power and internet cables

Thanks to the immediate accessibility of sockets and LAN connections, the new products from the expert for electrical installation and housing technology make any work process easier, be it in industrial buildings, workshops or on machines. They not only ensure a fast and secure Internet connection and comfortable working at the installation site, but also a tidy overall picture.


Ready-to-connect housing solution for quick installation

The manufacturer from Schalksmühle has further developed its tried-and-tested STV 1224-K and STV 922-K socket combinations and added an RJ45 data installation socket to the equipment with RCDs and MCBs, two CEE and four or two SCHUKO® sockets . The type-tested solutions are ready to connect and thus enable enormous time savings during installation, as the wiring effort is kept to a minimum.


Suitable for any installation site thanks to its durability

Both models have compact dimensions so that they can be unobtrusively integrated into any installation environment. The version with two SCHUKO® sockets, one CEE 16A and one CEE 32A socket and an RJ45 data built-in socket (STV 922-K-LAN) measures 200 x 400 x 122 mm, the one with four SCHUKO® sockets, a CEE 16A and a CEE 32A socket as well as an RJ45 built-in data socket (STV 1224-K-LAN) 250 x 400 x 122 mm. Thanks to their insensitivity to high temperatures and mechanical loads, the halogen-free power distributors are even suitable for harsh environments such as warm or dirty production sites. The socket distributors are of industrial quality, have the high degree of protection IP44 and have an impact resistance of IK08. In this way, the sensitive electronic and electromechanical components inside the housing are reliably protected against dust, moisture and other harmful effects. As a provider of complete solutions, Spelsberg also enables flexible combinations with products from the AK small distribution board series.

Spelsberg has expanded its range of socket distributors and housings by two variants that feature data sockets mounted on the side and thus enable the uncomplicated connection of network cables.



In addition to four SCHUKO sockets and two CEE sockets, the STV 1224-K-LAN version also has a built-in data socket. It ensures both a fast and secure Internet connection and a tidy overall picture at the installation site.

EMR Additional Notes:

  • LAN (Local Area Network):
    • A local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.
    • By contrast, a wide area network not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.
    • LAN networking requires Ethernet cables and Layer 2 switches along with devices that can connect and communicate using Ethernet. Larger LANs often include Layer 3 switches or routers to streamline traffic flows.
    • A LAN enables users to connect to internal servers, websites and other LANs that belong to the same wide area network (WAN). Ethernet and Wi-Fi are the two primary ways to enable LAN connections.
    • Ethernet is an Institute of Electrical and Electronics Engineers (IEEE) specification that enables computers to communicate with each other. Wi-Fi uses radio waves in the 2.4 gigahertz and 5 GHz spectrum to connect computers to the LAN.
  • WLAN (Wireless Local-Area Network):
    • Goup of colocated computers or other devices that form a network based on radio transmissions rather than wired connections. A Wi-Fi network is a type of WLAN; anyone connected to Wi-Fi while reading this webpage is using a WLAN.
    • A wireless LAN is a wireless computer network that links two or more devices using wireless communication to form a local area network within a limited area such as a home, school, computer laboratory, campus, or office building.


  • Switchgears:
    • Performs the function of controlling and metering the flow of electrical power in addiction to acting as interrupting and switching devices that protects the equipment from damage arising out of electrical fluctuations.
  • Circuit Breakers:
    • Mechanical electrical switch to protect electrical circuit against short circuit or overload.
  • Fuses:
    • Single time mechanical circuit interruption in an over-current situation through fusion of a graded electrical conductor. Employed in 30KV to 100KV range.
