Socket outlet frame berker WNA403 for 3-gang installation, compatible with Hager WNA403

berker WNA403 socket outlet frame for 3-gang installation is a mounting frame designed to hold three modules—such as socket outlets, switches or combination modules—in a single coordinated unit. Supplied as one frame, it provides a clean border and mechanical support for standard 3-module configurations and is compatible with housings and modules that accept this form factor.

Advantages

The frame simplifies installation by providing a ready-made three-module opening with consistent spacing and alignment. Its single-piece construction reduces installation time and helps achieve a uniform appearance across adjacent devices. Compatibility with widely used module dimensions ensures straightforward integration with common switch and socket elements.

Suitable for

• Residential electrical installations where three modules are required in one location
• Office or commercial spaces needing coordinated multiple socket/switch units
• Replacement or upgrade projects where an existing 3-gang opening is maintained

When it may not be suitable

This frame is intended specifically for a three-module (3-gang) arrangement; it is not suitable for single or non-standard module sizes. It does not include the internal socket or switch mechanisms, mounting boxes, or screws, so additional components are required to complete an installation.

Key specifications

• Application: mounting frame for three adjacent modules (3-gang)
• Material: manufactured from durable insulating material suitable for visible trim (material details as supplied by manufacturer)
• Finish: surface finish designed to match compatible device ranges (visual consistency with corresponding cover plates)
• Mounting: designed for standard module spacing and flush wall installation in compatible housings
• Package: single-piece frame supplied as one unit

How to use

Position the frame over the prepared mounting box or compatible assembly so that the three module openings align with the installed devices. Secure the underlying modules or mounting support according to the device manufacturer’s instructions, then fit the frame by snapping or fastening it into place as designed. Ensure electrical work is carried out with power isolated and in accordance with local regulations.

What to consider before purchase

• Confirm the frame dimensions and module spacing match the sockets and switches to be installed
• Verify compatibility with the existing mounting box or surface-mounted housing
• Plan for the necessary internal devices (sockets, switches) and fixing hardware, which are not included

Usage recommendations

For a reliable installation, combine this 3-gang frame with compatible modules from the same range or confirmed compatible manufacturers. Follow manufacturer guidance for mounting and adhere to local electrical codes; if unsure, use a qualified electrician to perform the installation.
