## Summary description

Rittal AS 4051.545 insulated ferrules for wire termination. Copper conductor with polypropylene (PP) insulation, suitable for 0.75 mm² (AWG 18) conductors, 10 mm insertion length. Supplied in a pack of 4000 pieces for reliable crimp connections in control cabinets, switchgear and industrial wiring.

## Long description

Rittal AS 4051.545 insulated ferrules are crimp end sleeves designed for secure wire termination in control cabinets, switchgear and industrial electrical installations. Each ferrule features a copper conductor tube with a polypropylene (PP) insulating collar, sized for 0.75 mm² (AWG 18) conductors and a 10 mm insertion length. Supplied as a pack of 4000 pieces, these ferrules provide consistent contact area and reliable mechanical protection for stranded conductors during crimping and connection.
Advantages
The combination of a copper conductor and polypropylene insulation ensures good electrical conductivity and basic mechanical protection at the termination point. The 10 mm tube length provides sufficient conductor insertion depth for a secure crimp, reducing the risk of stray strands and improving contact reliability. Supplied in a large pack of 4000 pieces, the product supports bulk installation needs and helps maintain consistent crimp quality across multiple terminations.
Suitable for
 Termination of single-core stranded conductors with cross-section 0.75 mm² (AWG 18)
 Internal wiring in control cabinets and switchgear
 Industrial and machine wiring where standardized insulated ferrules are required
 Panel building and repetitive assembly tasks requiring consistent crimp results
When it may not be suitable
These ferrules are intended for conductors with a nominal cross-section of 0.75 mm²; they are not suitable for significantly larger or smaller conductor sizes. For applications requiring higher environmental sealing, special insulation materials or fully insulated bootlace ferrules with specific approvals, alternative products should be considered. They are also not intended for use as a substitute for soldered terminations where soldering is explicitly required by design standards.
Key specifications
 Conductor material: copper tube
 Insulation material: polypropylene (PP) collar
 Nominal conductor cross-section: 0.75 mm² (AWG 18)
 Insertion length: 10 mm
 Quantity: 4000 pieces per pack
 Design: insulated ferrules with plastic collar for crimp terminations
How to use
Strip the stranded conductor to the recommended length, insert the conductor fully into the ferrule tube until the insulation collar sits against the conductor insulation. Use an appropriately sized crimping tool or die set for 0.75 mm² ferrules and perform a single, firm crimp to ensure a compact connection. After crimping, verify mechanical stability and electrical continuity. Install the terminated conductor into the terminal block, connector or lug as required.
What to consider before purchase
 Confirm conductor cross-section is 0.75 mm² (AWG 18) for proper fit
 Ensure your crimping tool and dies are compatible with 0.75 mm² insulated ferrules
 Assess whether polypropylene insulation meets the environmental and electrical requirements of your application
 Bulk quantity is 4000 pieces; consider storage and handling needs for large packs
Usage recommendations
For consistent results, use a calibrated crimping tool matched to 0.75 mm² insulated ferrules and inspect a sample crimp for correct compression and strand retention. Store the pack in a dry, dust-free environment to preserve insulation integrity and organise ferrules by batch when working on large projects to track consistent performance.
