Junction box for thermal insulation KEZ-3 200 mm KB (3xSOCKET) KEZ-3_KB

Insulation junction boxes – protection and functionality in one

The KEZ-3 KB electrical junction box is designed for mounting devices in building insulation systems. Designed to eliminate thermal bridges, it provides not only a safe electrical installation but also helps maintain the building's energy efficiency. Made of durable thermoplastic material, the box is resistant to weather conditions and mechanical damage. Its gray color (RAL 7035) allows for discreet integration with the facade.

Design and application

The KEZ-3 KB box is designed for flush mounting and allows the installation of two or three electrical devices. The set includes high-quality expansion plugs and mounting screws, which facilitate and speed up the installation process. Additionally, the included partition wall allows for separation of electrical circuits, increasing safety. The box is ideal for use in buildings insulated with polystyrene or mineral wool with an insulation layer thickness of 100 to 250 mm. In the case of mounting on thicker plaster, it is recommended to additionally seal with silicone to ensure complete tightness and protection against moisture.
