## Summary description

Rittal AS 4051.550 crimp ferrules for insulated cables, made of copper with polypropylene (PP) insulation. Rated for 1.0 mm² (AWG 18) conductors, with an 8 mm barrel length and 3.5 mm outer diameter. Supplied in a pack of 4000 pieces, these ferrules ensure reliable conductor termination and improved connection quality in control cabinets, panel wiring and industrial installations.

## Long description

Rittal AS 4051.550 crimp ferrules are designed for reliable termination of stranded conductors in control cabinets, panel wiring and industrial electrical installations. Each ferrule features a copper sleeve with a polypropylene (PP) insulated collar, sized for 1.0 mm² (AWG 18) conductors. The barrel length is 8 mm and the outer diameter is 3.5 mm. Supplied in a pack of 4000 pieces, these ferrules simplify repeated terminations and support consistent, secure connections where screw or clamp connections are used.
Advantages
These crimp ferrules provide consistent conductor compression on crimping, reducing strand fraying and ensuring a reliable electrical and mechanical connection. The copper conductor sleeve offers good electrical conductivity and corrosion resistance, while the PP insulated collar facilitates insertion into terminal blocks and provides strain relief. Available in a large pack of 4000, they are suitable for projects and maintenance tasks that require many terminations, helping to reduce downtime and material handling.
Suitable for
 Terminating stranded copper conductors sized 1.0 mm² (AWG 18)
 Control cabinets and industrial panel wiring where consistent crimps are required
 Applications requiring insulated collars for easier insertion into terminals
 Maintenance, production runs, or installation projects needing bulk quantities
When it may not be suitable
These ferrules are intended specifically for 1.0 mm² (AWG 18) stranded conductors; they are not suitable for solid conductors or significantly larger or smaller conductor cross-sections. They are not designed for use as a permanent mechanical protection against heavy vibration without additional strain relief measures.
Key specifications
 Conductor cross-section: 1.0 mm² (AWG 18)
 Material (sleeve): copper
 Insulation material (collar): polypropylene (PP)
 Barrel length: 8 mm
 Outer diameter: 3.5 mm
 Pack quantity: 4000 pieces
How to use
Strip the stranded conductor to the appropriate length, insert the strands into the copper sleeve so that no individual strands are left outside the barrel, and position the PP collar flush with the insulation. Use a suitable crimping tool or ferrule crimper selected for 1.0 mm² ferrules and perform a single, firm crimp to achieve full compression of the sleeve. After crimping, verify the mechanical retention and electrical continuity before final assembly into the terminal or connector.
What to consider before purchase
 Confirm conductor type and cross-section (1.0 mm² / AWG 18) to ensure compatibility
 Verify that your crimping tool supports ferrules for 1.0 mm² to obtain reliable crimps
 Consider pack size (4000 pcs) relative to project needs and storage
 Check terminal or connector entry diameter to ensure the 3.5 mm outer diameter collar will fit
Usage recommendations
Use matched crimping dies for 1.0 mm² ferrules and perform a pull test on a sample of crimps after installation to confirm mechanical retention and electrical continuity. Store the pack in a dry environment and handle ferrules with clean tools to prevent contamination of contact surfaces.
