Mounting and installation information for junction boxes Introduction Junction boxes are used to connect cables and can be the harmful ingress of water. By contrast, the so-called IK mounted in all kinds of areas. With regard to the ambient code represents the protection rating against mechanic- conditions, several factors and standardised specifica- al loads.
Chemical influences Water build-up, frost 1.2. Protection against UV radiation OBO Bettermann developed the junction boxes of the T UV radiation can cause major structural damage to vari- and X series for these applications. These products are ous plastics. This damage may even lead to destruction.
Depending on the type, OBO Bettermann's junction boxes of the various product groups can offer a break-out The X series from OBO Bettermann is resistant to min- or condensation water opening to be pushed in. This is eral oils and various vegetable and animal fats.

Mounting and installation information for junction boxes 2. Protection ratings according to IEC 60529 (VDE 470-1) The IP protection rating specifies how far a component is protected against contact and foreign bodies and the ingress of water. The IP protection ratings are controlled by the standard DIN EN 60529 (VDE 0470 Part 1).

Mounting and installation information for junction boxes 4.2. T series ‒ the all-rounder If you want a little more, the junction boxes, made from high-quality materials with sensible wall thicknesses, are particularly stable and thus perfectly equipped to han- dle greater loads. Thanks to the UV-stabilised plastic and the IP66 protection rating, they can also withstand weathering conditions in indoor areas and, under certain circumstances, those in outdoor areas as well.
Mounting and installation information for junction boxes 4.3. X series – the extreme athlete Professionals are at work here: The junction boxes are high-quality and robust. With its impact resistance of IK09, the X series can withstand the strongest me- chanical loads.
Mounting and installation information for junction boxes 4.4. Mx series – the robust one Our aluminium empty housings were designed for use under the toughest conditions and provide optimum pro- tection of the installation. The metal housing of the Mx series withstands extremely high and low temperatures, as well as large temperature differences.
