## Summary description

Rittal AS 4051.599 ferrules (aderendhülsen) are copper-core, polypropylene (PP)-insulated wire end sleeves in white. Each sleeve measures 8 mm length and 2.8 mm diameter. Supplied in a pack of 5000 pieces, they provide reliable conductor termination for electrical panels, control cabinets and industrial wiring to ensure secure crimped connections.

## Long description

Rittal AS 4051.599 ferrules are copper-core wire end sleeves with polypropylene insulation in white, designed for reliable conductor termination in industrial and electrical installations. Each ferrule features an 8 mm insulated length and a 2.8 mm internal diameter, supplied in a bulk pack of 5000 pieces. The ferrules include a plastic collar to aid positioning and consistent crimping, helping to protect stranded conductors and improve connection quality in control cabinets, switchgear and general wiring applications.
Advantages
These ferrules combine a conductive copper core with a polypropylene insulating sleeve to provide secure, low-resistance terminations while offering mechanical protection to the conductor strands. The plastic collar facilitates easier insertion into terminal blocks and prevents insulation damage during crimping. Supplied in a large 5000-piece pack, they are suitable for repeated assembly work and maintenance, reducing the need for frequent reorders.
Suitable for
Termination of stranded copper conductors in control cabinets and switchboards
Industrial wiring and panel building where consistent crimped connections are required
Field and workshop assembly tasks that require bulk quantities of ferrules
Protecting conductor strands at screw or spring-type terminal connections
When it may not be suitable
These ferrules are intended for use on copper conductors; they are not suitable for aluminium conductors or for applications that require specific high-temperature or chemical-resistant insulation materials. They are sized for conductors compatible with an 8 mm insulated length and a 2.8 mm internal diameter; using them on markedly larger or smaller conductors will not provide reliable terminations.
Key specifications
Insulation material: polypropylene (PP)
Conductor core: copper
Insulated length: 8 mm
Internal diameter: 2.8 mm
Colour: white
Quantity per pack: 5000 pieces
Includes plastic collar for positioning
How to use
Strip the conductor to the appropriate length so that the bare strands fit fully into the ferrule barrel. Insert the stranded copper conductor into the ferrule until the insulation butts against the plastic collar. Use a suitable crimping tool sized for 2.8 mm ferrules and apply a single solid crimp to compress the barrel onto the conductor. After crimping, verify that the ferrule is secure and that no loose strands are visible. Then insert the terminated conductor into the terminal and secure according to the terminal manufacturer’s instructions.
What to consider before purchase
Ensure conductor cross-section and strand construction are compatible with an 8 mm length and 2.8 mm internal diameter ferrule
Confirm compatibility with your crimping tool and terminal types (screw or spring terminals)
Assess whether polypropylene insulation and the supplied plastic collar meet environmental and temperature requirements for your application
Consider pack size (5000 pcs) relative to project needs and storage
Usage recommendations
For consistent results use a calibrated crimping tool matched to the ferrule size, strip conductors cleanly, and inspect crimped terminations visually and mechanically. Store the ferrules in a dry environment and keep them protected from direct sunlight to preserve the polypropylene insulation.
