## Summary description

Rittal AS 4051.641 is a crimp ferrule with a copper sleeve and polypropylene (PP) insulated collar. It has an 8 mm sleeve length and 2.8 mm outer diameter, designed for reliable wire termination and improved conductor contact. Suitable for insulating and consolidating stranded conductors prior to screw or terminal connections in control cabinets and electrical installations.

## Long description

Rittal AS 4051.641 is a set of ferrules with a plastic collar designed to provide reliable termination for stranded wires. The ferrules combine a copper crimp sleeve with a polypropylene (PP) insulating collar and are finished in white. Their compact dimensions—8 mm length and 2.8 mm diameter—make them suitable for use where space is limited and consistent crimp quality is required.
Advantages
The copper sleeve ensures good electrical conductivity and corrosion resistance, while the polypropylene collar offers electrical insulation and simplifies insertion into terminals. The plastic collar also helps maintain wire shape after crimping, improving connection reliability and enabling easier identification and handling during assembly.
Suitable for
 Crimp termination of stranded wires in control cabinets and distribution blocks
 Electrical panels, terminal strips, and relay/socket connections
 Applications requiring consistent, secure wire ends in limited space
When it may not be suitable
These ferrules are intended for specific wire cross-sections matching the 8 mm length and 2.8 mm diameter; they may not fit very fine or very large conductors. They are not designed as a standalone insulation solution for high-voltage insulation requirements beyond standard terminal protection.
Key specifications
 Material: copper sleeve with polypropylene (PP) collar
 Colour: white
 Length: 8 mm
 Diameter: 2.8 mm
How to use
Strip the conductor to the appropriate length, insert the stranded wire into the ferrule until the conductor reaches the copper sleeve, and crimp using a suitable ferrule crimping tool. After crimping, verify a firm mechanical connection and ensure the plastic collar seats properly in the terminal to provide insulation and strain relief.
What to consider before purchase
 Confirm compatibility with the conductor cross-section and the terminal size
 Ensure the crimping tool is rated for ferrules of this size
 Consider any colour-coding or identification practices in your installation
Usage recommendations
Use a calibrated crimping tool matched to ferrule dimensions for consistent electrical contact. Verify each crimp by a gentle pull test and ensure terminals are tightened to the manufacturer's torque specifications.
