## Summary description

Rittal AS 4051.687 ferrules are insulated wire end sleeves made of copper with polypropylene insulation in red.

Supplied in a pack of 500, these ferrules provide secure, reliable conductor termination for control cabinets, terminal blocks and harness assemblies.

## Long description

Rittal AS 4051.687 ferrules are insulated wire end sleeves designed for secure termination of 1.0 mm² conductors. Each ferrule features a copper crimp barrel with a red polypropylene insulating collar, measuring 12 mm in length and approximately 3.5 mm in outer diameter. Supplied in a pack of 500, these ferrules are intended for use in control cabinets, terminal strips and wiring harnesses where reliable electrical connection and protection of stranded conductors are required.
Advantages
These ferrules combine a copper conductive core with a polypropylene insulating collar to ensure good electrical contact and improved mechanical stability at the conductor termination. The standard length and diameter support consistent crimping and insertion into terminal blocks, reducing the risk of stray strands and improving connection reliability. Supplied in a bulk pack, they are suitable for repetitive installations and service operations, reducing handling time and ensuring a consistent supply of matching ferrules.
Suitable for
 Crimp termination of stranded copper conductors rated 1.0 mm²
 Wiring in control cabinets and distribution panels
 Terminal blocks, relays and contactors with matching wire entry
 Electrical harness assembly and repair work
 Maintenance work requiring bulk quantities of insulated ferrules
When it may not be suitable
These ferrules are specified for conductors with a cross-sectional area of 1.0 mm²; they are not suitable for larger or smaller conductor sizes. They are intended for copper conductors and should not be used with aluminum or dissimilar metals without appropriate transition measures. The polypropylene collar provides basic insulation and strain relief but is not a substitute for full insulation or environmental sealing in exposed or harsh outdoor conditions.
Key specifications
 Conductor nominal cross-section: 1.0 mm²
 Barrel material: copper
 Insulation material: polypropylene (polymer collar)
 Insulation color: red
 Overall length: 12 mm
 Approximate outer diameter: 3.5 mm
 Pack quantity: 500 pieces
How to use
Strip the conductor to the recommended length, insert the stranded copper conductor fully into the ferrule barrel so that no strands protrude, and crimp the ferrule with an appropriate insulated ferrule crimping tool sized for 1.0 mm² ferrules. After crimping, verify the mechanical retention and electrical continuity; then insert the ferrule into the terminal or connector and secure the screw or clamp according to the terminal manufacturer's instructions. Follow standard safety practices for live or energized wiring.
What to consider before purchase
 Confirm conductor size: suitable for 1.0 mm² stranded copper conductors only
 Verify terminal entry dimensions to match the ferrule length and diameter
 Ensure you have the correct crimping tool for insulated ferrules of this size
 Consider pack quantity (500) relative to project needs and storage
Usage recommendations
Use a dedicated insulated ferrule crimping tool calibrated for 1.0 mm² ferrules and perform sample pulls to confirm crimp quality. Store ferrules in a dry environment and keep them in original packaging until use to maintain cleanliness. For installations exposed to vibration or harsh conditions, combine proper crimping with appropriate cable routing and strain relief measures.
