## Summary description

Rittal AS 4050.754 is a ferrule (wire end sleeve) with a copper conductor and polypropylene (PP) insulation. It has an 8 mm length and 2.8 mm outer diameter, designed for reliable crimped connections on stranded conductors to ensure consistent contact, prevent fraying, and simplify terminal insertion in control cabinets, terminal blocks and industrial wiring.

## Long description

Rittal AS 4050.754 is a set of ferrules with a plastic collar designed for secure termination of stranded wires. The ferrules combine a copper conductive sleeve with a polypropylene (PP) insulating collar and are finished in white. Each ferrule has a length of 8 mm and an inner conductor diameter suitable for crimping stranded conductors with a 2.8 mm outer diameter.
Advantages
The copper sleeve ensures reliable electrical conductivity and corrosion resistance while the polypropylene collar provides insulation and strain relief during installation. The plastic collar also aids identification and neat wiring in distribution blocks and terminal strips. Compact dimensions make these ferrules suitable for confined terminal spaces.
Suitable for
Crimping stranded copper wires into terminal blocks
Electrical cabinets, distribution panels and control cabinets
Industrial and commercial wiring where neat, reliable terminations are required
When it may not be suitable
These ferrules are intended for use with stranded conductors that match the specified diameter; they are not suitable for solid conductors or for stranded wires significantly larger or smaller than the indicated size. They are not intended to replace insulated bootlace terminals when different insulation properties are required.
Key specifications
Color: White
Material: Copper sleeve with polypropylene (PP) collar
Length: 8 mm
Suitable conductor diameter: approximately 2.8 mm
How to use
Strip the required length of insulation from the stranded conductor, insert the conductor into the ferrule until the strands are fully inside the copper sleeve, and crimp with a suitable ferrule crimping tool. After crimping, check the mechanical and electrical integrity of the connection and insert the ferruleled wire into the terminal and secure the terminal screw as required.
What to consider before purchase
Verify conductor cross-section and outer diameter to ensure compatibility
Ensure chosen ferrule length fits the terminal depth
Confirm material and collar color meet installation and identification requirements
Usage recommendations
Use a dedicated crimping tool sized for ferrules of this diameter to achieve a reliable, gas-tight connection; inspect crimps visually and by gentle pull test to confirm correct installation.
