## Summary description

Rittal AS 4050.774 are copper crimp ferrules with a white polypropylene (PP) insulated sleeve. Designed for terminating stranded conductors, they have a length of 8 mm and a barrel diameter of 2.8 mm. These ferrules ensure reliable crimped connections, improved contact surface and insulation for electrical panels, control cabinets and wiring installations.

## Long description

Rittal AS 4050.774 is a ferrule with a plastic collar designed to improve the reliability of wire terminations. It combines a copper conductive sleeve with a polypropylene (PP) insulated collar and is supplied in white colour. The product is intended for crimping onto stranded conductors to provide a secure, corrosion‑resistant connection and to prevent stray strands from causing shorts.
Advantages
The copper sleeve ensures good electrical conductivity and corrosion resistance while the polypropylene collar provides insulation and strain relief at the wire termination. Its small dimensions make it suitable for compact electrical panels and dense terminal blocks. The white collar colour helps with visual identification and colour‑coded wiring schemes.
Suitable for
Crimping onto stranded copper conductors to form insulated ferrules
Use in control cabinets, terminal blocks, and junction blocks
Applications requiring clear colour coding and compact wire termination
When it may not be suitable
The ferrule is intended for relatively small conductor sizes (length 8 mm, sleeve diameter 2.8 mm) and may not be appropriate for larger gauge wires or high‑current applications. It is not designed for direct exposure to extreme temperatures or aggressive chemicals; in such environments, select ferrules or terminals specified for those conditions.
Key specifications
Material: copper sleeve with polypropylene (PP) insulating collar
Colour: white (insulating collar)
Length: 8 mm
Sleeve diameter: 2.8 mm
How to use
Strip the conductor to the correct length so the bare wire fully inserts into the copper sleeve. Insert the stranded conductor into the ferrule until the insulation meets the collar, then crimp using an appropriate insulated ferrule crimping tool following the tool manufacturer's instructions. After crimping, verify a firm mechanical and electrical connection and that no wire strands protrude.
What to consider before purchase
Confirm the ferrule dimensions (length 8 mm, sleeve diameter 2.8 mm) match the conductor cross‑section and terminal requirements
Ensure the polypropylene collar and copper sleeve meet the environmental and electrical demands of your application
Verify colour‑coding needs—white collar may be used for specific wiring schemes
Usage recommendations
Use a properly sized insulated ferrule crimping tool and inspect each crimp for mechanical security and correct insulation position; store ferrules in a dry, clean environment to prevent contamination before installation.
