## Summary description

Rittal AS 4051.603 ferrules (aderendhülsen) are copper‑plated, polypropylene insulated cable end sleeves in red. Each sleeve measures 8 mm in length with a 3.5 mm diameter. Sold as a bulk pack of 5000 pieces, they provide reliable conductor crimping and insulation for terminating stranded wires in electrical panels and control cabinets.

## Long description

Rittal copper-plated polypropylene ferrules AS 4051.603 are insulated cable end sleeves designed for reliable termination of stranded conductors. Each ferrule combines a copper-plated metal tube for electrical contact with a polypropylene collar for insulation and strain relief. The sleeves are red, 8 mm in length and have a 3.5 mm internal diameter. Supplied as a bulk pack of 5000 pieces, they are intended for use where consistent crimped connections and clear colour coding are required in electrical panels and control cabinets.
Advantages
These ferrules provide a secure electrical connection through copper-plated inner tubes that ensure good conductivity and resistance to corrosion. The polypropylene collar simplifies insertion into terminals and improves insulation, while the uniform dimensions support consistent crimping quality when using a suitable crimping tool. The red colour allows immediate visual identification according to common colour-coding practices.
Suitable for
 Terminating stranded wires in distribution boards and control cabinets
 Crimping onto conductors for screw, spring, or clamp-type terminals
 Applications requiring large quantities of colour-coded end sleeves
 Panel building, industrial electrical installations, and maintenance work
When it may not be suitable
These ferrules are intended for stranded conductors and are not suitable for solid single-core wires where end sleeves are typically unnecessary. They are sized for conductors compatible with an 8 mm length and 3.5 mm diameter sleeve; using them with significantly larger or smaller conductors may compromise crimp integrity or fit.
Key specifications
 Material: copper-plated metal tube with polypropylene insulated collar
 Colour: red
 Length: 8 mm
 Internal diameter: 3.5 mm
 Pack quantity: 5000 pieces
How to use
Strip the stranded conductor to the appropriate length, insert the conductor strands fully into the metal tube of the ferrule, and position the polypropylene collar against the insulation. Use a suitable insulated ferrule crimping tool sized for the ferrule diameter to crimp the metal tube evenly until a secure mechanical and electrical connection is achieved. After crimping, verify that the ferrule is firmly attached and that no stray strands are protruding before inserting into the terminal.
What to consider before purchase
 Confirm that the ferrule internal diameter and length match the conductor cross-section and the terminal dimensions.
 Ensure compatibility with your crimping tool and the required crimping profile for reliable connections.
 Assess whether bulk packaging of 5000 pieces suits your usage rate and storage capacity.
 Verify that red colour coding aligns with your wiring colour-coding scheme or standards.
Usage recommendations
For consistent results, use a calibrated crimping tool appropriate for 3.5 mm ferrules and perform a pull test on sample crimps. Store the pack in a dry, dust-free environment to maintain insulation integrity and prevent contamination of the copper-plated surfaces.
