Product information

Description

Rittal AS 4051.548 ferrules with plastic collar are insulated wire end sleeves designed to provide a secure and reliable termination for stranded conductors. Made from copper with a polypropylene (PP) plastic collar, these white ferrules help ensure consistent contact, prevent strand fraying and improve connection quality in control cabinets, distribution blocks and terminal strips.

Advantages

The copper tube provides good electrical conductivity and mechanical strength while the PP collar offers insulation and ease of insertion into terminals. The compact 8 mm length and 2.9 mm diameter make these ferrules suitable for confined terminal spaces. Supplied in packs of 4000 pieces, they are convenient for larger wiring jobs and repetitive assembly tasks.

Suitable for

  • Insulating and terminating stranded wires 0.5 mm² (AWG 20)
  • Electrical panels, control cabinets and terminal blocks
  • Industrial assembly lines and electrical maintenance work

When it may not be suitable

These ferrules are specified for conductors with a cross-section of 0.5 mm² (AWG 20); they are not suitable for larger or significantly smaller conductor sizes. They are intended for crimp termination and require a properly sized crimping tool for reliable results.

Key specifications

  • Colour: White (plastic collar)
  • Conductor cross-section: 0.5 mm² (AWG 20)
  • Material: Copper tube with polypropylene (PP) collar
  • Length: 8 mm
  • Outer diameter: 2.9 mm
  • Quantity per pack: 4000 pieces

How to use

Strip the conductor to the appropriate length, insert the stranded wire into the copper tube until the insulation meets the plastic collar, and crimp firmly with a crimping tool sized for 0.5 mm² ferrules. After crimping, check the mechanical and electrical integrity of the connection before energising the circuit.

What to consider before purchase

  • Confirm conductor cross-section is 0.5 mm² (AWG 20)
  • Ensure you have a compatible crimping tool for insulated ferrules
  • Verify terminal dimensions to match the 8 mm length and 2.9 mm diameter

Usage recommendations

Use the ferrules with the correct crimping tool and inspect crimps visually and mechanically; store packs in a dry environment to prevent contamination of the contact surfaces.
