The WAGO support rail type 790-145 is a component for mounting electrical modules on standard support rails in industrial applications. It is specifically designed for use with WAGO products that are mounted on support rails, such as terminal blocks or other connection technology modules. The rail has a length of 1000 mm and is tinned, ensuring a corrosion-resistant surface. The silver-colored coating is typical for tinned metal parts and serves mechanical and electrical stability.

Support rail

The support rail 790-145 serves as a mounting element for electrical components in an enclosure. It enables standardized, quick, and secure installation of modules equipped with support rail mounting. The special hole pattern is designed for use with WAGO products, particularly for modules secured with M5 screws. The hole pattern is designed to ensure a secure and stable connection without requiring additional fastening elements.

Applications

The rail is intended for use in industrial electrical installations, enclosures, and control systems. It is commonly used in automation technology, machine building, and during the installation of distributors. The tinning makes it particularly suitable for environments requiring high corrosion resistance, such as humid or slightly aggressive operating conditions.

Functions and equipment in detail

The support rail features a special hole pattern designed for mounting modules with M5 screws. This specific design enables precise and secure fastening of the modules. The tinning of the surface ensures good electrical conductivity and prevents oxide formation, enhancing the long-term stability of the connection. The silver-colored surface is a visual indicator of the tinning and reflects the material quality.

Technology explained simply

The special hole pattern of the support rail is not only a mechanical feature but also ensures precise fit with WAGO modules. The spacing and shape of the holes are designed to enable secure and repeatable mounting. Tinning is an electroplating process where a thin zinc layer is applied to the base material to prevent corrosion and maintain electrical conductivity. This is particularly important in industrial applications, where the rail is often under load for extended periods.

Compatibility and accessories

The support rail 790-145 is specifically designed for use with WAGO products. Suitable accessories include, for example, the spacer sleeve 790-144, which is specially perforated for support rails with M5 screws. This spacer sleeve can be used to adjust the mounting height or spacing between modules, which is helpful when installing modules with different mounting requirements.

Mounting and installation

Mounting is done by securing the rail at the desired location in the enclosure, for example, using screws or other fastening elements. The special hole pattern enables secure mounting of WAGO modules placed on the rail. The rail is typically installed horizontally to provide a stable base for the modules. The tinning facilitates installation, as it does not require additional coatings or pre-treatment.

Advantages in operation

Using the support rail 790-145 provides a standardized mounting base that simplifies the installation and maintenance of electrical modules. The special hole pattern ensures secure and repeatable fastening, increasing the reliability of the system. The tinning ensures long service life and minimizes the risk of corrosion, which is particularly beneficial in demanding operating environments. The silver-colored surface is a visual indicator of quality and material selection.
