General
Colour	Yellow/Green

The Helavia A3x25-C JV rubber grommets from Ses-Sterling are specifically designed for use in electrical and installation technology. These rubber grommets serve as cable protection and cable clamps for secure and tight fixation of cables in cable entries, e.g. in switch cabinets, distribution boxes or other electrical enclosures. The grommets are finished in the colour yellow/green, identifying them as protective conductor – a marking that is mandatory in electrical engineering for earth and protective conductors. The designation A3x25-C JV indicates the specific version, with dimensions and material quality designed for reliable performance in industrial and commercial applications.

Applications
These rubber grommets are intended for use in electrical installations, particularly where cables must be passed through enclosure walls. They provide mechanical stabilisation of the cables and simultaneously protect against mechanical stresses such as friction, pressure or tension. The yellow/green colour coding identifies them as protective conductors, requiring clear assignment to earthing and protective conductors in electrical installation technology. The grommets are suitable for indoor use and environments with moderate ambient conditions, with a temperature resistance from -30 °C to +90 °C enabling a wide range of applications.

Functions and Equipment in Detail
The rubber grommets Helavia A3x25-C JV are made from an elastic rubber material offering high flexibility and shape stability. The inner surface is designed to adapt elastically when the cable is inserted, ensuring a secure, pressure-tight fit. The external shape is cylindrical with a conical transition, allowing easy installation into drill holes. The yellow/green colour is not only visually identifiable but also complies with the standard for protective conductors, enabling clear identification during installation. The grommets are available in a pack of 100 pieces, making them suitable for series installations and larger projects.

Technology Explained Simply
The rubber grommets function as cable clamps by elastically enclosing the cable upon insertion and applying a firm but non-damaging pressure. This prevents the cable from slipping out of the hole over time or being damaged by vibrations. The material composition ensures high elasticity and resistance to mechanical stress. The temperature resistance from -30 °C to +90 °C allows use in a wide range of environments, from air-conditioned rooms to industrial facilities with elevated temperatures. The yellow/green colour is required by DIN VDE 0100-510 and other relevant standards for protective conductors to enable unambiguous identification.

Compatibility and Accessories
The rubber grommets Helavia A3x25-C JV are designed for use with cables in cable entries, particularly in switch cabinets, distribution boxes or other electrical enclosures. They are compatible with drill holes matching the specific diameter of the grommet, with precise fit ensured by the elastic material structure. The grommets are not specifically designed for particular accessories but serve as a universal cable protection solution. Installation requires no additional tools or aids – mounting is achieved by simply inserting the cable into the grommet and then inserting it into the drill hole.

Installation and Mounting
Mounting of the rubber grommets is done by inserting the cable into the grommet, where the elastic structure adapts to the cable diameter. The grommet is then inserted into the designated drill hole in the enclosure. The elastic shape ensures adaptation to the hole and provides a tight, mechanically stable fit. Installation requires no additional tools or aids. The grommets are intended for use in electrical installations, with the yellow/green colour ensuring clear assignment to the protective conductor.

Operational Advantages
The rubber grommets Helavia A3x25-C JV provide reliable mechanical stabilisation and protection for cables in cable entries. The elastic material structure ensures a tight but non-damaging fit, protecting the cable from mechanical stress. The yellow/green colour enables clear identification as a protective conductor, facilitating compliance with safety regulations and standards. The temperature resistance from -30 °C to +90 °C extends the range of applications in various environments. The pack of 100 pieces makes them particularly suitable for larger installations and series mounting.
