## Summary description

Rittal AS 4051.600 is an insulated wire end ferrule composed of a copper conductor and polypropylene (PP) insulation, sized for 0.75 mm² conductor cross-section. Each sleeve is 10 mm long with a 2.8 mm diameter. Supplied in a pack of 5000, these ferrules provide reliable termination for stranded wires in electrical panels, control cabinets and industrial installations.

## Long description

Rittal AS 4051.600 ferrules are insulated wire end sleeves designed for terminating stranded conductors with a cross-section of 0.75 mm². Each sleeve combines a copper conductor with polypropylene (PP) insulation, measures 10 mm in length and has an outer diameter of approximately 2.8 mm. Supplied in a bulk pack of 5000 pieces, these ferrules are intended for consistent, reliable crimped connections in electrical panels, control cabinets and other industrial wiring applications.
Advantages
The construction uses a copper inner sleeve for good electrical conductivity and corrosion resistance, while the polypropylene insulation ensures mechanical protection and electrical isolation. The 10 mm length and 2.8 mm outer diameter provide a compact termination that fits common terminal blocks and connectors. Supplied in a large pack of 5000, the product supports high-volume assembly and maintenance tasks with uniform quality and consistent dimensions.
Suitable for
 Terminating stranded copper conductors of 0.75 mm² cross-section
 Use in electrical panels and control cabinets
 Industrial installations and machinery wiring
 Mass wiring or repetitive assembly work thanks to bulk packaging
When it may not be suitable
These ferrules are specifically sized for 0.75 mm² conductors; they are not suitable for larger or smaller conductor cross-sections. The polypropylene insulation is designed for mechanical protection and basic electrical isolation but may not be appropriate where elevated temperature ratings or special chemical resistance are required.
Key specifications
 Conductor material: copper inner sleeve
 Insulation material: polypropylene (PP)
 Nominal conductor cross-section: 0.75 mm²
 Overall sleeve length: 10 mm
 Outer diameter: approximately 2.8 mm
 Pack quantity: 5000 pieces
 With plastic collar for improved wire alignment during crimping
How to use
Strip the stranded conductor to the appropriate length for the ferrule, insert the conductor fully into the copper sleeve so that all strands are contained, and position the plastic collar against the insulation. Use a suitable insulated ferrule crimping tool sized for 0.75 mm² ferrules and apply a single crimp to compress the copper sleeve securely around the conductor. After crimping, inspect the termination to ensure there are no loose strands and that the crimp is uniform. Fit the ferrule-terminated wire into the intended terminal block or connector and tighten the terminal according to the connector manufacturer’s torque recommendation.
What to consider before purchase
 Confirm that the conductor cross-section is 0.75 mm² and compatible with the ferrule dimensions
 Verify that terminal blocks or connectors accept a 10 mm ferrule length and ~2.8 mm diameter
 Ensure you have a compatible crimping tool for insulated ferrules of this size
 Evaluate whether polypropylene insulation meets environmental, temperature and chemical resistance requirements for your application
Usage recommendations
For repeatable, reliable terminations use a dedicated, calibrated crimping tool sized for insulated ferrules of 0.75 mm². Perform a sample pull test during initial installation to confirm crimp quality, and store the bulk pack in a dry environment to avoid contamination prior to use.
