OBO junction box portfolio
The portfolio of OBO connectable junction boxes includes a total of around 20 different connectable cover concepts. Both unequipped variants and equipped, pre-wired variants with Wieland and Wago plug-in systems are available. The different configurations meet the comprehensive installation requirements of current construction projects, while providing for faster mounting times and greater flexibility on the construction site.
Four cover variants with one thing in common: greater flexibility
The OBO connectable junction boxes have four different cover types:




Pre-wired covers with Wieland plug-in systems and cable sections: They also contain the OBO lever terminal block to make it even easier for installers to connect the cable ends.
Pre-wired covers with Wieland and Wago plug-in systems and cable sections: This variant contains not only the OBO lever terminal block, but also integrated blue plugs for DALI and offers the option to retrofit BST14 plug-in systems from Wieland
Covers with a combination of possible plug-in systems and sockets from OBO’s own Modul 45 series that have to be separated with a barrier strip due to standard requirements. This barrier strip is also available as a separate accessory.
Cover for the application of data technology systems such as USB or Sat. Five different data technology inserts are available. The installer can integrate the data technology systems based on Keystone.
Clever accessories round off the portfolio
An extensive range of accessories rounds off the portfolio of connectable junction boxes. Like the junction boxes themselves, the range is tailored to the practical requirements of installers and tradespeople.

Inserts for DATA systems
Different inserts for the integration of data technology systems such as USB or Sat

Separating plate
For standardised separation of alternating current and data cables within a cover

Flexible fastening element
A design so variable that the boxes can be fastened both horizontally and vertically.
