Junction boxes for thermal insulation systems – reliability and ease of installation

The KEZ-3/Z_KB box is a dedicated solution for electrical installations in thermal insulation systems. Made of durable plastic, it provides safe and aesthetic cable routing in insulated exterior walls. It is a replacement element, often used as a cover in standard KEZ-3 boxes, to cover unused openings. Please note that this is not a load-bearing element, but only a masking one.

Functionality and technical parameters

The box is designed for wall or ceiling mounting and is characterized by a wide range of operating temperatures, from -25°C to 60°C. The possibility of using cables with a cross-section of up to 4 mm² makes it compatible with most standard electrical installations. Equipped with inlets at the back, it facilitates cable routing, and the gray color provides a discreet appearance. Halogen-free construction increases safety, minimizing the risk of toxic gases in the event of a fire.
