## Summary description

Rittal AS 4051.601 insulated ferrules (aderendhülsen) in yellow finish, made of copper conductive tube with polypropylene (PP) insulation. Each ferrule has an 8 mm length and 3 mm diameter, suitable for secure termination of stranded wires. Supplied in a pack of 5000 pieces for industrial and electrical panel wiring applications.

## Long description

Rittal AS 4051.601 insulated ferrules in yellow are wire end terminals designed for professional electrical connections. Each ferrule combines a copper conductive tube and a polypropylene (PP) insulated collar to provide a reliable crimp termination for stranded wires. With an overall ferrule length of 8 mm and an inner diameter suited for 3 mm conductor bundles, these ferrules come in a bulk pack of 5000 pieces intended for panel building, control cabinets, and other industrial wiring tasks.
Advantages
These insulated ferrules provide consistent electrical contact by securing stranded conductors in a compact copper sleeve while the polypropylene insulation prevents stray strands and offers strain relief at the termination point. The yellow finish supports colour-coding in complex installations, and the packed quantity of 5000 ensures continuity of production or maintenance work without frequent restocking.
Suitable for
Termination of stranded copper conductors requiring a 3 mm ferrule inner diameter
Electrical panel and control cabinet wiring in industrial or commercial settings
Applications needing colour-coded terminations for easy identification
High-volume assembly or maintenance where bulk quantities reduce handling time
When it may not be suitable
These ferrules are intended for use with stranded copper conductors that fit the specified internal diameter and are not suitable for solid single-core conductors or conductors larger than the stated size. They are not replacement components for insulated crimp connectors designed for different wire gauges or for applications requiring special high-temperature or chemical-resistant insulation materials.
Key specifications
Ferrule length: 8 mm
Inner diameter / conductor size compatibility: designed for a 3 mm conductor bundle
Material — conductive sleeve: copper
Insulation material: polypropylene (PP) collar
Finish / colour: yellow
Pack quantity: 5000 pieces
How to use
Strip the appropriate length of insulation from the stranded conductor, insert the exposed strands fully into the copper tube of the ferrule so that the insulation collar meets the conductor insulation, and crimp using a suitable insulated ferrule crimping tool sized for the ferrule dimensions. After crimping, verify mechanical retention and electrical continuity. The polypropylene collar helps centre the conductor and provides a neat, safe termination for insertion into terminals or screw clamps.
What to consider before purchase
Verify that the ferrule inner diameter (3 mm) and 8 mm length match the conductor cross-section and the terminal depth of your equipment
Ensure compatibility with your crimping tool and die set for reliable, gas-tight crimps
Confirm that polypropylene insulation and the yellow colour meet any industry or site marking requirements
Usage recommendations
Use a calibrated ferrule crimper and choose the correct die for 8 mm × 3 mm ferrules. For reliable long-term connections, check crimps periodically in high-vibration or high-current applications and keep spare ferrules available to maintain workflow in production or maintenance environments.
