## Summary description

Rittal AS 4050.785 terminal ferrules made of copper with polypropylene (PP) insulation. Each ferrule has a 12 mm length and 6.3 mm diameter, supplied in a pack of 100. Designed to provide secure, low-resistance termination for stranded conductors in electrical panels, switchgear and industrial control cabinets.

## Long description

Rittal AS 4050.785 terminal ferrules are copper conductive sleeves with polypropylene (PP) insulation and a plastic collar, designed for secure termination of stranded conductors in electrical panels, switchgear and industrial control cabinets. Each ferrule measures 12 mm in length and has a 6.3 mm outer diameter. Supplied in a pack of 100, these ferrules facilitate reliable crimped connections that reduce contact resistance and protect conductor strands from fraying during insertion into terminal blocks and screw connections.
Advantages
These terminal ferrules combine a copper inner sleeve for good electrical conductivity with a polypropylene insulated collar that provides strain relief and insulation. The 12 mm length ensures sufficient insertion depth for many terminal types, and the 6.3 mm diameter matches common conductor and terminal sizes. Packed in quantities of 100, they offer a practical amount for small installation jobs or maintenance kits. The plastic collar simplifies handling during crimping and helps to maintain a neat, consistent termination.
Suitable for (tasks / use cases)
Terminating stranded copper conductors in control cabinets and distribution panels
Wire-to-terminal connections in switchgear and industrial automation equipment
Maintenance and repair work where standardised, repeatable crimps are required
Assembly tasks that need insulated ferrules to prevent strand splaying and improve contact reliability
When it may not be suitable
These ferrules are intended for use with stranded copper conductors; they are not suitable for solid conductors or for direct use with aluminium conductors without an appropriate bi-metallic connector or compatible treatment. The specified length and diameter are designed for typical terminal sizes — applications requiring significantly longer sleeves or different diameters should use alternate ferrule sizes.
Key specifications
Material: copper conductive sleeve with polypropylene (PP) insulation and plastic collar
Length: 12 mm
Outer diameter: 6.3 mm
Pack quantity: 100 pieces
Intended conductor type: stranded copper conductors
How to use
Select the ferrule size that matches the conductor cross-section and the terminal entry. Strip the conductor to the appropriate length so that the strands fit fully into the copper sleeve. Insert the stranded conductor into the ferrule until the insulation collar meets the conductor insulation, then crimp firmly with a suitable ferrule crimping tool to create a gas-tight mechanical and electrical connection. After crimping, insert the terminated conductor into the terminal and secure the screw or clamp according to the terminal manufacturer's instructions.
What to consider before purchase
Confirm compatibility with conductor cross-section and terminal entry dimensions
Ensure ferrule length and diameter suit your terminal type and available insertion depth
Verify that you are using stranded copper conductors; consider appropriate products for aluminium or mixed-metal connections
Usage recommendations
For consistent results, use a calibrated crimping tool matched to insulated ferrules and verify crimps visually and mechanically. Store ferrules in a dry environment to avoid contamination of the conductive surfaces and keep an inventory of common sizes to reduce downtime during assembly or maintenance tasks.
