Incobex insulating panel 4 mm for enclosure STN 26×42×25 cm (model TUP-20250)

Incobex insulating panel 4 mm for enclosure STN 26×42×25 cm (model TUP-20250) is a 4 mm thick dielectric sheet designed to fit inside small electrical enclosures with internal dimensions 26×42×25 cm. The panel provides an insulating barrier between live components and the metal cabinet walls, enabling safer mounting of electrical devices and helping to prevent accidental short circuits. It is suitable for retrofitting or original installation in control boxes where a dedicated insulating surface is required.

Advantages

The 4 mm thickness offers mechanical stability while maintaining a compact profile that fits the specified enclosure size. The insulating material reduces the risk of electrical contact with the metal housing and supports the secure installation of terminal blocks, DIN rails and protective devices. The panel is cut to match the internal dimensions of the enclosure, simplifying installation and saving time compared with custom trimming.

Suitable for

• Insulating inner surface of STN 26×42×25 cm electrical enclosures
• Mounting terminal blocks and small DIN-rail components
• Creating an isolation barrier to reduce short circuit risk
• Retrofit or replacement in control cabinets and junction boxes

Key specifications

• Material thickness: 4 mm
• Designed internal fit: 26×42×25 cm enclosures
• Function: electrical insulation and protective barrier
• Suitable for mounting terminal blocks, DIN rails and circuit protection devices
• Form: flat panel sized to match enclosure interior

How to use

Place the insulating panel inside the STN 26×42×25 cm enclosure so that it rests against the internal walls and aligns with any mounting points. Fasten the panel using appropriate non-conductive spacers or mounting hardware, ensuring clearance for cable entry points and ventilation if required. Mount terminal blocks, DIN rails or protective devices onto the panel using recommended fasteners for the chosen components. Verify that the panel provides the necessary electrical clearance and that all live parts remain insulated from the metal housing.

Usage recommendations

Ensure compatibility between the panel and the enclosure before installation. Use appropriate non-conductive mounting hardware and respect manufacturer spacing requirements for mains and low-voltage components. Inspect the panel for damage before use and replace if warped or cracked. For installations exposed to high humidity, elevated temperatures, or chemical vapors, verify the material suitability for the specific environment.
