The Helavia A3a-FC lg 25 rubber grommets from Ses-Sterling are specifically designed for use in electrical and installation technology. These rubber grommets serve as cable glands and enable a secure, tight, and flexible fixation of cables in switch cabinets, distribution boxes, or other electrical enclosures. The designation lg 25 refers to the length of the grommet, which is 25 mm, and the color is yellow, providing visual identification in the installation environment. The grommets are made of an elastic rubber material that offers high flexibility and shape stability, allowing cables of different diameters to be securely fixed.

Applications
These rubber grommets are particularly suitable for use in electrical distributors, switch enclosures, and other enclosed installation systems where mechanical and electrical insulation of cables is required. They prevent dust, moisture, or small particles from entering the enclosure, thereby preserving the functionality and service life of installed components. The yellow color serves as visual identification, for example, to distinguish between different cable types or to identify lines with special functions.

Functions and Equipment in Detail
The grommets are designed as cable glands, with the material allowing elastic expansion so that cables of different diameters can be securely and tightly inserted. The shape is cylindrical with a conical transition, ensuring secure anchoring in the enclosure thread. The yellow color is not only visually identifiable but can also be used for cable classification in accordance with installation regulations or company guidelines.

Technology Explained Simply
The rubber grommets are made of an elastic material that expands when the cable is inserted and then contracts again, creating a tight fit. This prevents foreign objects from entering and protects electrical connections. The length of 25 mm allows sufficient anchoring in the enclosure thread, ensuring secure fixation. The yellow color is a visual feature that can be used for quick identification during installation. The grommets are not intended for use in explosive environments or under extreme mechanical stress.

Compatibility and Accessories
The grommets are used in conjunction with cables whose diameter falls within the elastic expansion range of the grommet.

Installation and Mounting
Mounting is done by inserting the grommet into the thread of the enclosure, where the conical shape ensures secure anchoring. Subsequently, the cable is passed through the grommet, causing the material to wrap around the cable and create a tight seal. The grommets are designed for manual installation; no special tools or mounting aids are required. The packaging contains 100 pieces, suitable for larger installations or series mounting.

Each grommet weighs 0.75 g, indicating a compact and lightweight design. The packaging weight is 0.075 kg, corresponding to the total mass of 100 pieces.

Operational Advantages
The rubber grommets offer a simple and reliable solution for cable fixation and sealing in electrical installations. The yellow color supports visual differentiation during installation, which can reduce the error rate during mounting. The elastic shape ensures a tight fit that remains intact even under slight vibrations or movements during operation. The grommets are suitable for indoor use and provide a cost-effective solution for standard installations.
