Colour	Blue

The Helavia A3x25-FM rubber grommets from Ses-Sterling are specifically designed for use in electrical and installation technology. They serve as a cable gland for secure and tight fixation of cables in cable entries, particularly in switch cabinets, distribution boxes, or other electrical enclosures. The grommets are available in the colour blue and are made of an elastic material that ensures reliable sealing and mechanical stabilisation of the cables. The designation A3x25-FM indicates the specific version, with the marking FM referring to a particular shape or function within the Helavia series.

Applications
These rubber grommets are suitable for use in industrial electrical installations as well as in building and machine construction technology. They are used to fix cables when passing through enclosure walls or lids, while simultaneously providing mechanical protection and a certain sealing effect. The grommets are designed for cables with a diameter of up to 25 mm, with the exact fit ensured by the elastic structure of the material. The blue colour serves as a visual identifier and facilitates recognition during the installation process.

Functions and Features in Detail
The Helavia A3x25-FM grommets are designed as rubber grommets, meaning they are made of a flexible, rubber-like material that elastically adapts to the shape of the cable. This ensures secure fixation without damaging the cable. The grommets are designed for temperature resistance from -30 to 90 °C, making them suitable for use in a wide range of environments, including industrial facilities, outdoor areas, or rooms with fluctuating temperatures. The elastic structure allows for easy installation and simultaneous mechanical stabilisation of the cable.

Technical Explanation
The grommets operate on the principle of a cable gland, where the cable is passed through an elastic opening that wraps around the cable to create a secure connection. The elastic expansion of the material ensures that the cable does not slip and simultaneously provides a certain sealing effect, protecting against dust, moisture, or small particles. The designation A3x25-FM refers to the specific design and the maximum cable dimensions that can be accommodated with this grommet. The blue colour is a visual feature intended for quick identification.

The grommets are available in a pack of 1000 pieces, making them particularly suitable for large-scale installations or series mounting. The weight of a single unit is 0.525 g, indicating a compact and lightweight construction.

Compatibility and Accessories
The Helavia A3x25-FM grommets are designed for cables with a diameter up to 25 mm. They are compatible with standard cable entries in electrical enclosures and distribution boxes that feature a corresponding hole or opening for mounting. The grommets can be used in combination with other installation components such as cable ties, screw terminals, or protective conduits to ensure a complete and secure cable installation. There are no specific accessories directly associated with this item, as the grommets are supplied as individual components.

Installation and Mounting
Installation is carried out by simply inserting the grommet into the designated opening in the enclosure and then passing the cable through the central opening of the grommet. The elastic structure ensures the cable is securely held without requiring additional fastening elements. The grommets are designed for easy manual installation and do not require special tools. They are typically used without additional mounting aids, as the elastic shape of the material provides the necessary holding force.

Operational Advantages
The Helavia A3x25-FM grommets provide reliable and durable cable fixation in electrical enclosures. The elastic structure ensures a secure connection that remains stable even under vibrations or movements during operation. The temperature resistance from -30 to 90 °C makes them suitable for a wide range of operating conditions. The blue colour facilitates identification and sorting during the installation process. The pack of 1000 pieces is ideal for large projects and series installations, thereby increasing the cost-effectiveness and efficiency of the installation.
