## Summary description

Rittal AS 4050.766 is a wire end ferrule with a copper conductor and polypropylene (PP) insulation, finished in white. It has an 8 mm ferrule length and a 2.8 mm diameter, designed to provide reliable crimped terminations on stranded conductors. Suitable for electrical panel wiring, terminal blocks and control cabinet applications where secure, compact wire ends are required.

## Long description

The Rittal AS 4050.766 is a white insulated ferrule designed for secure termination of stranded copper conductors. Made from copper with a polypropylene (PP) plastic collar, it provides a compact, reliable connection for control cabinets and electrical panels where neat, insulated wire ends are required. The ferrule has a length of 8 mm and an inner conductor diameter of 2.8 mm.
Advantages
The polypropylene collar protects against fraying and ensures reliable insulation at the wire end while the copper sleeve provides solid electrical contact and corrosion resistance typical for copper. Its compact dimensions make it suitable for tight terminal spaces and standard wiring applications, and the colour coding helps quick identification during wiring and maintenance.
Suitable for
Insulation and termination of stranded copper conductors in control cabinets and distribution boards
Applications requiring neat, insulated wire ends for screw or clamp terminals
Electrical maintenance and panel assembly where space is limited
When it may not be suitable
This ferrule is intended for stranded copper wires and may not be appropriate for solid conductors or aluminium cables. It is a small-diameter ferrule (2.8 mm inner diameter); for larger conductors you will need a ferrule with a larger sleeve diameter and length suited to the conductor cross-section.
Key specifications
Material: Copper sleeve with polypropylene (PP) collar
Product colour: White (collar)
Length: 8 mm
Inner diameter: 2.8 mm
How to use
Strip the insulation from the stranded copper conductor to the appropriate length, insert the conductor into the ferrule until the strands are fully inside the copper sleeve, and crimp the sleeve using a suitable ferrule crimping tool following the tool manufacturer's instructions. After crimping, check that the collar sits flush against the wire insulation and that the crimp is secure before inserting into terminals.
What to consider before purchase
Compatibility with the conductor type and cross-section (stranded copper)
Required inner diameter and ferrule length for the target wire
Whether the white colour coding matches your wiring identification system
Usage recommendations
Use a dedicated ferrule crimping tool sized for 2.8 mm ferrules and verify crimp quality visually and mechanically to ensure dependable electrical contact and insulation.
