Cable outlet insert berker W.1 IP55 WNA155B, polar white, splashproof protection

berker W.1 cable outlet insert WNA155B in polar white is a splashproof accessory designed to create a protected and tidy cable passthrough for power and data cables. Rated to IP55, the insert provides ingress protection against dust and water jets, and includes features for strain relief and secure routing when installed in walls, cabinets or enclosures. The compact, neutral-colour design integrates with modular electrical systems and supports both indoor and semi‑outdoor installations where splash protection and orderly cable management are needed.

Advantages

The splashproof outlet insert offers IP55-level protection to reduce dust and water ingress at cable entry points while providing mechanical strain relief that helps prevent cable and connector damage. Its polar white finish matches common switch and socket ranges and keeps the installation visually discreet. The insert is designed for straightforward integration into mounting openings and supports tidy routing of multiple cable types without additional seals or bulky enclosures.

Suitable for

• Creating sealed cable passthroughs for power and data cables in walls and partitions
• Routing cables into electrical cabinets, media boxes or distribution enclosures
• Indoor and semi‑outdoor locations where splash protection (IP55) is required
• Installations that require strain relief to protect connectors and cables

When it may not be suitable

This insert is intended for splashproof protection and strain relief up to the IP55 level; it is not designed for continuous immersion or high-pressure washdown conditions. For environments requiring higher ingress protection (for example full submersion or industrial washdown), a product rated to a higher IP level should be selected. The insert is sized for standard cable routing and may not accommodate very large-diameter conduits without additional adapters.

Key specifications

• Protection rating: IP55 (splashproof and dust-protected)
• Colour: polar white
• Function: cable passthrough with strain relief
• Application: wall, cabinet or enclosure cable entry
• Suitable cable types: power and data cables (various common diameters)

How to use

Install the outlet insert into a compatible mounting opening in the wall or enclosure following the mounting dimensions of the modular system. Route the cable through the insert and position the strain relief element to secure the cable, ensuring that the sealing surfaces align to maintain IP55 protection. Tighten any retaining screws or clamps as required by the mounting design. After installation, check that cables are held firmly and that there are no gaps around the insert that would compromise ingress protection.

What to consider before purchase

• Confirm the mounting opening dimensions and compatibility with your existing frame or modular system
• Verify that IP55 protection is sufficient for the intended environment (not suitable for immersion)
• Check cable diameters to ensure they fit the insert’s strain-relief range
• Ensure the polar white colour matches other visible components in the installation

Usage recommendations

For reliable protection, install the insert in dry conditions and inspect seals after making changes to cable routing. Use appropriate grommets or additional sealing where cables with unusual diameters are used, and periodically check the strain-relief clamp for secure retention to prevent movement or wear.
