## Long description

berker 457309 is a junction box with a mixed metal and plastic construction and a metallic finish, intended for indoor electrical installations. It offers IP20 protection suitable for dry, protected environments and provides a stable enclosure for cable splices, terminations and electrical connections. The unit is designed for mounting with spreader claws and includes a supporting plate and plug-in terminals to simplify wiring and secure conductor connections up to 10 mm².
Advantages
The combination of plastic and metal materials ensures mechanical stability while keeping weight moderate. A matt metallic surface appearance provides a discreet finish that blends with interior design. The integrated plug-in terminals with screw connections on the rear facilitate safe and fast terminations. IP20 protection gives basic protection against access to hazardous parts and solid objects, making the box suitable for indoor service environments. Installation is simplified by the spreader-claw mounting system and the included supporting plate.

How to use
