## Summary description

Rittal AS 4051.625 insulated ferrules in yellow, made with copper conductor tube and polypropylene insulating collar. Each ferrule has a 6.3 mm outer diameter and 10 mm length. Supplied as 100 pieces per pack, these ferrules provide reliable wire termination for electrical connections and improve crimp quality and contact reliability in control cabinets and wiring harnesses.

## Long description

Rittal AS 4051.625 insulated ferrules in yellow combine a copper conductor tube with a polypropylene insulating collar to provide consistent, reliable wire terminations. Each ferrule measures 6.3 mm in outer diameter and 10 mm in length and is supplied in a pack of 100. These ferrules are intended for crimping onto stranded conductors to improve contact area, reduce strand fraying, and ensure secure connections in control cabinets, terminal blocks and wiring harnesses.
Advantages
The copper conductor tube ensures good conductivity and mechanical stability while the polypropylene insulating collar offers electrical insulation and easy handling during assembly. Supplied as a set of 100 pieces, the ferrules allow consistent crimp quality across multiple terminations and reduce installation time compared with untinned wires. The yellow colour supports visual identification and wiring organisation.
Suitable for
 Crimp termination of stranded copper conductors in control cabinets and switchgear
 Connection to screw or clamp-type terminal blocks
 Wiring harnesses and industrial panels requiring consistent contact reliability
 Applications where visual identification by colour-coding is beneficial
When it may not be suitable
These ferrules are designed for stranded copper conductors of a compatible cross-section; they are not intended for use on solid conductors or on conductors outside the compatible size range. They are not a replacement for specialised high-voltage or high-temperature terminations where materials with different ratings are required.
Key specifications
 Conductor material: copper tube for the crimp barrel
 Insulation material: polypropylene collar
 Outer diameter: 6.3 mm
 Length: 10 mm
 Colour: yellow
 Quantity: 100 pieces per pack
How to use
Strip the conductor to the appropriate length, insert the stranded conductor fully into the copper tube of the ferrule, and crimp using a suitable ferrule crimping tool that matches the ferrule size. After crimping, verify that the conductor is held firmly and that the insulating collar sits flush with the termination point. Then connect the ferrule-ended conductor to the terminal or clamp and secure according to the equipment manufacturer's torque specifications.
What to consider before purchase
 Confirm the ferrule dimensions match the conductor cross-section and the terminal entry size
 Ensure the polypropylene insulation rating is suitable for the operating temperature and environment
 Verify colour-coding fits your wiring identification scheme
 Check you have a compatible crimping tool for reliable, reproducible crimps
Usage recommendations
For best results use with stranded copper conductors of the recommended size and a dedicated ferrule crimper. Inspect crimps visually and mechanically on first installations and follow terminal manufacturer torque data to maintain reliable electrical connections.
