## Summary description

Rittal AS 4050.779 are insulated terminal ferrules with a copper conductive tube and polypropylene (PP) insulation in white. With a tube length of 8 mm and a diameter of 2.8 mm, they provide reliable conductor termination and improved contact for stranded wires. Intended for electrical panel wiring, control cabinets and industrial installations where secure, vibration-resistant wire connections are required.

## Long description

Rittal AS 4050.779 ferrule with plastic collar is a small electrical termination component designed to provide a reliable connection for stranded wires. The ferrule combines a copper crimp sleeve with a polypropylene (PP) plastic collar and comes in white colour. It is specified for an 8 mm length and a 2.8 mm diameter, suitable for neat, secure wire terminations in control cabinets and electrical enclosures.
Advantages
The combination of a copper sleeve and polypropylene collar ensures good electrical conductivity together with mechanical protection at the wire end. The plastic collar aids alignment during insertion into terminals and helps prevent fraying of stranded conductors. Its compact dimensions (8 mm length, 2.8 mm diameter) make it appropriate for use in confined terminal strips and dense wiring assemblies.
Suitable for
 Crimping onto stranded copper conductors to form a secure termination
 Use in industrial control cabinets, distribution blocks and terminal strips
 Applications requiring colour-coded ferrules for identification (white collar)
When it may not be suitable
Not suitable for use with solid conductors or non-copper conductors where a different termination method is required. It may also be unsuitable for very large gauge wires that exceed the physical diameter or current-carrying capacity implied by the 2.8 mm diameter specification.
Key specifications
 Material: Copper sleeve, polypropylene (PP) plastic collar
 Colour: White
 Length: 8 mm
 Diameter: 2.8 mm
How to use
Strip the conductor to the appropriate length, insert the stranded copper wire fully into the ferrule so that strands are contained within the copper sleeve, and crimp the ferrule using a suitable crimping tool for insulated or uninsulated ferrules. After crimping, insert the ferrule into the terminal and tighten the terminal screw to secure the connection.
What to consider before purchase
 Confirm compatibility with the conductor cross-section and terminal dimensions
 Verify that a white collar meets your colour-coding or identification requirements
 Ensure you have a suitable crimping tool for ferrules of this size
Usage recommendations
Use the ferrule with appropriately sized stranded copper conductors and a matched crimping tool to achieve a reliable electrical and mechanical connection; avoid using it on solid conductors or on wires that exceed the ferrule's diameter.
