## Summary description

Rittal AS 4051.623 ferrules are copper conductors with polypropylene (PP) insulation designed for terminating 1.5 mm² wires. Each insulated sleeve is 12 mm long with a 3.5 mm outer diameter. Supplied in a pack of 500, these ferrules ensure reliable crimped connections for control cabinets, switchgear and general electrical installations.

## Long description

Rittal AS 4051.623 ferrules are copper conductors with polypropylene (PP) insulation designed to terminate 1.5 mm² single-core wires. Each insulated sleeve measures 12 mm in length and has an outer diameter of 3.5 mm, providing a consistent contact area for crimped connections. Supplied in a pack of 500, these ferrules are intended for use in control cabinets, switchgear and general electrical installations where reliable, repeatable terminations are required.
Advantages
These ferrules combine a copper conductor with a polypropylene insulated collar to offer good electrical conductivity together with mechanical protection for the wire end. The uniform sleeve length and diameter support consistent crimp quality, reduce stray wire strands, and improve insertion into terminal blocks and screw connections. The polypropylene insulation provides electrical isolation and a degree of strain relief while remaining compatible with common hand and pneumatic crimping tools.
Suitable for
 Terminating 1.5 mm² solid or stranded single-core copper conductors
 Control cabinets, distribution boards and switchgear wiring
 Industrial and building electrical installations requiring standardized ferrules
 Applications where a pack quantity of 500 supports batch wiring and maintenance
When it may not be suitable
These ferrules are specifically sized for 1.5 mm² conductors; they will not provide a correct fit for significantly larger or smaller wire cross-sections. They are intended for copper conductors and are not suitable for bare aluminium conductors without appropriate treatment or transition sleeves. For high-temperature environments beyond typical installation ranges, polypropylene insulation may not offer sufficient thermal resistance and alternative materials should be considered.
Key specifications
 Conductor material: copper
 Insulation material: polypropylene (PP)
 Nominal conductor cross-section: 1.5 mm²
 Sleeve length: 12 mm
 Outer diameter (insulation): approx. 3.5 mm
 Pack quantity: 500 pieces
 With insulated plastic collar for improved handling
How to use
Strip the conductor to the appropriate length so that the bare wire fully enters the ferrule sleeve without excess exposed conductor. Insert the wire strands straight into the copper sleeve and position the insulated collar against the insulation of the cable. Use a suitable crimping tool matched to 1.5 mm² ferrules and apply consistent pressure until a secure crimp is formed. After crimping, check that there are no stray strands, that the ferrule is firmly attached and that the assembly inserts smoothly into the intended terminal or connector.
What to consider before purchase
 Ensure compatibility with 1.5 mm² copper conductors used in your installation
 Verify that polypropylene insulation is acceptable for your operating temperature range
 Confirm that your crimping tools support insulated ferrules of this size
 Assess whether a pack of 500 matches your project or maintenance needs
Usage recommendations
For reliable results, use a calibrated crimping tool designed for insulated ferrules and inspect a sample crimp for mechanical integrity and electrical continuity before committing to large-scale assembly. Store ferrules in a dry environment and handle them to avoid contamination of the copper sleeve.
