Product information

Description

Kopos MDZ 300 KB 120×120×315 mm is a junction box designed for recessed installation in external thermal insulation systems. The box provides an internal cavity for cable terminations and small electrical components while maintaining the continuity of insulated façades. Its rectangular form and specified internal volume are intended to fit within insulation layers and allow reliable protection of connection points against mechanical stress and weather influence when installed according to façade insulation practice.

Advantages

The junction box is manufactured from material suitable for use inside external thermal insulation systems and features a shape and depth that permit organized routing of conductors. It supports recessed mounting without disrupting the thermal layer when correctly embedded, and its dimensions offer sufficient working space for standard connection tasks. The product facilitates neat termination of cables and contributes to reduced risk of thermal bridging when integrated properly in insulation assemblies.

Suitable for

  • Recessed mounting inside external thermal insulation composite systems (ETICS)
  • Housing electrical cable junctions and terminations within insulated façades
  • Installation of small electrical components and connection blocks inside wall insulation
  • Applications requiring maintenance of thermal integrity around junction points

Key specifications

  • External application: designed for use inside external thermal insulation systems
  • Shape and size: rectangular box with nominal face dimensions 120 × 120 mm
  • Depth: 315 mm, providing expanded internal volume for cable routing and terminations
  • Material: durable plastic suitable for embedding in insulation layers (non-metallic)
  • Mounting method: recessed installation into insulation layer with plaster or adhesive covering

How to use

Install the junction box by recessing it into the prepared cavity within the insulation layer so that the front face aligns with the finished insulation surface. Secure the box according to the insulation system manufacturer's instructions using adhesive or mechanical fixing appropriate for the insulation material. Route and terminate conductors inside the box, leaving required clearances for connection blocks and ensuring that any openings are sealed in line with external moisture and fire safety requirements. After wiring, cover and finish the box opening with the compatible finishing layer of the thermal insulation system.

Usage recommendations

Use this junction box only with compatible external thermal insulation systems and follow local electrical codes. Ensure proper sealing and mechanical fixation to preserve thermal performance and weather resistance. For installations involving higher ingress protection or specific fire rating requirements, select additional covers or accessories rated for those conditions.
