## Summary description

Rittal AS 4050.783 are electrical ferrules with a copper conductive tube and polypropylene insulating collar. Each ferrule is 12 mm long with a 4.8 mm outer diameter; supplied in a pack of 500. Designed for reliable conductor termination and improved crimping, they are suitable for panel wiring, control cabinets and industrial electrical installations.

## Long description

Rittal AS 4050.783 copper polypropylene ferrules are termination sleeves designed to provide reliable electrical contact and consistent crimping for stranded conductors. Each ferrule combines a copper conductive tube with a polypropylene insulating collar, measures 12 mm in length and has an outer diameter of 4.8 mm. Supplied as a pack of 500, these ferrules are intended for use in panel wiring, control cabinets and other industrial electrical installations where repeatable, secure conductor connections are required.
Advantages
These ferrules offer a defined copper contact area that improves electrical continuity and reduces the risk of stray strands. The polypropylene collar supports insulation and simplifies insertion into terminal blocks and screw clamps. Consistent dimensions and material choice help achieve uniform crimp quality across multiple conductors, while the bulk pack format supports larger wiring jobs and maintenance tasks.
Suitable for
 Terminating stranded copper conductors for screw-terminal and spring-clamp connections
 Panel and control-cabinet wiring in industrial and commercial installations
 Mass termination tasks and electrical maintenance where many identical ferrules are needed
When it may not be suitable
These ferrules are intended for use with copper conductors; they are not suitable for aluminium conductors or mixed-metal terminations unless proper transition treatments or bi-metallic components are used. They are also not insulated for high-voltage clearances beyond the collar rating, so applications requiring larger creepage distances or specialized insulating boots should use purpose-designed components.
Key specifications
 Tube material: copper conductive sleeve
 Collar material: polypropylene insulating collar
 Length: 12 mm
 Outer diameter: 4.8 mm
 Quantity: pack of 500 ferrules
How to use
Strip the conductor to the appropriate length so the strands fully enter the ferrule tube without exposed wire beyond the collar. Insert the stripped conductor into the ferrule until it seats against the collar, then crimp using a suitable insulated ferrule crimping tool sized for the ferrule diameter. After crimping, verify mechanical retention and electrical continuity. Insert the crimped ferrule into the terminal and tighten the screw or engage the spring clamp according to terminal manufacturer instructions.
What to consider before purchase
 Confirm compatibility with the conductor cross-section and the terminal type used in your installation
 Ensure your crimping tool matches the ferrule dimensions to achieve reliable crimps
 Verify that polypropylene collar and ferrule dimensions meet any clearance or insulation requirements for your application
Usage recommendations
Use these ferrules for stranded copper conductors within their specified size range, apply the correct strip length and crimp tool, and store the pack in a dry environment to preserve the polypropylene collar and copper surface quality.
