## Summary description

Rittal AS 4051.574 insulated ferrules for terminating 0.5 mm² conductors. Each ferrule has an 8 mm length, copper conductor and polypropylene (PP) insulation in orange. Supplied in a pack of 500, these ferrules provide reliable conductor crimping and improved contact for control cabinets, terminal blocks and electrical assemblies.

## Long description

Rittal AS 4051.574 insulated ferrules are designed for terminating 0.5 mm² conductors. Each ferrule measures 8 mm in length, features a copper conductor and polypropylene (PP) insulation in orange, and is supplied in a practical pack of 500. The plastic collar supports consistent crimping and protection of the conductor end, helping to ensure reliable electrical contact in control cabinets, terminal blocks and electrical assemblies.
Advantages
These insulated ferrules provide a solid copper conductor for low-resistance connections and a polypropylene insulator that resists deformation during crimping. The 8 mm length ensures enough insertion depth for secure crimping and contact, while the orange color enables quick visual identification and coding. Supplied in a bulk pack of 500, they are suitable for repeated assembly tasks and maintenance work, reducing the need for frequent replenishment.
Suitable for
Terminating stranded conductors of 0.5 mm² cross-section
Wiring and rebuilding terminal blocks in control cabinets
Industrial and building electrical assemblies requiring reliable crimped ends
Panel wiring and maintenance tasks where color coding improves organization
When it may not be suitable
These ferrules are specifically sized for 0.5 mm² conductors; they are not suitable for significantly larger or smaller conductor cross-sections. They are intended for crimp termination and are not a direct substitute for soldered connections or insulated splices that require different mechanical or environmental properties.
Key specifications
Conductor material: copper
Insulation material: polypropylene (PP)
Conductor cross-section supported: 0.5 mm²
Ferrule length: 8 mm
Color: orange (for identification and coding)
Pack quantity: 500 pieces
With plastic collar for improved crimping and strain relief
How to use
Strip the conductor to the recommended length, insert the stranded conductor fully into the ferrule so that strands are contained within the copper sleeve, and crimp using a properly sized insulated ferrule crimping tool. Ensure the plastic collar sits flush with the insulation or wire jacket for strain relief. After crimping, verify mechanical stability and electrical continuity before final installation into terminal blocks or panel wiring.
What to consider before purchase
Confirm conductor cross-section is 0.5 mm² to ensure correct fit
Verify required ferrule length (8 mm) matches stripping length and terminal depth
Ensure orange color coding suits your wiring scheme
Check pack size (500) aligns with consumption rates and storage capabilities
Usage recommendations
Use a dedicated crimping tool sized for 0.5 mm² insulated ferrules to achieve consistent crimps. Store packs in a dry environment to avoid contamination of the ferrule sleeves. For critical or safety-related circuits, perform a visual and pull test on a sample of crimps during installation to confirm mechanical integrity and good electrical contact.
