The Legrand marking system CAB 3-R (manufacturer number 038317) is a marking item for the unambiguous identification of electrical conductors. It is used for identifying cables and wires within installations, particularly in electrical engineering and building technology. The system enables the labelling of conductors with letters, numbers, and symbols, where the letter R in black on a yellow background is used. The marking is attached to the conductor using a clip mechanism, ensuring a secure and permanent fixation.

Applications
This marking system is specifically designed for conductors with a cross-section of 0.5 to 1.5 mm². It is therefore suitable for marking individual wires in electrical installations, for example in distributions, socket installations, enclosures, or during device cabling. The black-on-yellow colour combination is common in electrical engineering and supports visual differentiation of conductors, especially in complex systems. The marking is applied directly to the conductor, enabling quick identification even during later maintenance or repair work.

Functions and Equipment in Detail
The CAB 3-R consists of a single marking clip, distinguished by its simple handling. The clip is directly clipped onto the conductor without requiring additional tools or adhesives. The labelling is done using the pre-defined letter R, clearly and legibly placed on the yellow background. The colour scheme complies with common standards in electrical installation to ensure uniform and understandable marking. The marking is designed for indoor use and offers sufficient durability under normal operating conditions.

Technology Explained Simply
The clip is designed to elastically wrap around the conductor, ensuring a secure fixation. The material selection allows for a durable connection without damaging the conductor. The marking is pre-fabricated and cannot be altered after application. The black-on-yellow colour scheme is commonly used in electrical engineering to indicate specific functions or conductor types, with the exact meaning of the letter R defined within the respective project or according to standards such as DIN VDE 0100-510 or DIN EN 50418. The marking is not waterproof or dustproof, as no IP protection rating is specified.

Compatibility and Accessories
The CAB 3-R marking system is specifically designed for conductor cross-sections of 0.5 to 1.5 mm². It is part of Legrand’s CAB 3 system, which offers various letters and symbols in different colour combinations. It is used in combination with other CAB 3 system markings to ensure uniform marking within an installation.

Installation and Mounting
Installation is done by simply clipping the marking clip onto the conductor. No tools are required, and fixation is achieved through the elastic clip mechanism. The marking is immediately readable after application and remains attached to the conductor as long as no mechanical stress or damage occurs. Installation is performed directly on the conductor, with positioning according to the relevant installation regulations.

Operational Advantages
The clear and unambiguous marking with the letter R in black on yellow facilitates conductor identification during installation and during subsequent maintenance work. The simple, tool-free mounting saves time and reduces error potential. The marking remains securely attached and remains clearly readable even after prolonged use, increasing the reliability of the marking. Use within a uniform marking system enhances clarity and safety in electrical installations.
