## Summary description

Rittal AS 4051.644 are insulated ferrules (aderendhülsen) with a copper conductor and a polypropylene (PP) insulating tube in red. Each ferrule has a 10 mm length and 3 mm diameter, supplied in a pack of 1000. Designed for reliable wire termination, they ensure secure crimp connections on stranded conductors and improve contact quality in electrical panels and wiring harnesses.

## Long description

Rittal AS 4051.644 insulated ferrules are copper-conductor crimp end sleeves with a red polypropylene insulating tube. Each ferrule measures 10 mm in length and 3 mm in diameter, supplied in a pack of 1000. These ferrules are intended for terminating stranded conductors to provide secure, low-resistance connections in control cabinets, terminal blocks and wiring harnesses, and they include a plastic collar to facilitate insertion and reliable insulation at the wire end.
Advantages
Insulated ferrules with a copper conductor and polypropylene tube improve contact integrity by consolidating stranded wires into a uniform barrel that is easy to crimp. The 10 mm length offers sufficient insulation overlap for secure connections while the plastic collar helps alignment and prevents fraying of the conductor strands. Supplied in a large pack of 1000, they support repeated use across multiple terminations and minimize interruptions for maintenance or production tasks.
Suitable for
Crimp termination of stranded copper conductors in control panels and distribution blocks
Wiring harnesses in machinery, automation systems, and industrial equipment
Securing connections in terminal strips, relays, and screw-clamp connectors
Applications requiring color-coding for quick identification of conductor sizes or functions
When it may not be suitable
These insulated ferrules are designed specifically for stranded copper conductors within the dimensional range that matches a 3 mm bore. They are not suitable for solid conductors or for cable cross-sections outside the intended range. For extremely high-current applications or where specific flame-retardant or halogen-free insulation is required, alternative ferrules or terminations with certified ratings should be considered.
Key specifications
Conductor material: copper
Insulation material: polypropylene (PP) tube with plastic collar
Insulation color: red
Length: 10 mm
Barrel/inner diameter: 3 mm
Packaging: pack of 1000 pieces
How to use
Strip the conductor to the appropriate length so that the bare strands fully enter the ferrule barrel without exposing excess bare wire beyond the insulation. Insert the stranded copper conductor into the ferrule until the plastic collar sits flush with the conductor insulation. Use a suitable crimping tool matched to the ferrule size to apply a single, firm crimp on the barrel area. After crimping, verify mechanical retention and electrical continuity; install the terminated wire into the terminal or connector and secure according to the terminal manufacturer’s instructions.
What to consider before purchase
Confirm the ferrule barrel diameter and length match the conductor cross-section and insulation strip length you use
Ensure the polypropylene insulation and plastic collar meet any specific workplace or regulatory requirements for material properties
Verify compatibility with your crimping tool dies for consistent, certified crimps
Consider the pack size (1000 pieces) relative to your usage to avoid overstocking or frequent reordering
Usage recommendations
For reliable connections, use a calibrated crimping tool appropriate for 3 mm ferrules and inspect a sample of crimps periodically. Maintain consistent strip lengths and apply one proper crimp per ferrule to ensure low-resistance, vibration-resistant terminations in electrical panels and wiring harnesses.
