## Summary description

Rittal AS 4051.584 insulated ferrules for wire termination: 1.5 mm² conductor cross-section, 12 mm length, red insulation. Constructed with copper conductor and polypropylene (PP) insulating sleeve. Supplied in a pack of 500, suitable for reliable crimp connections in control cabinets, electrical panels and industrial wiring applications.

## Long description

Rittal AS 4051.584 insulated ferrules are designed for safe and reliable termination of 1.5 mm² conductors. Each ferrule combines a copper wire sleeve with a red polypropylene (PP) insulating collar and has a 12 mm overall length. Supplied in a pack of 500, these ferrules are intended for consistent crimp connections in control cabinets, electrical panels and industrial wiring tasks where solid contact and insulation are required.
Advantages
These insulated ferrules provide corrosion-resistant electrical contact through a copper conductor sleeve while the polypropylene insulation ensures mechanical protection and colour-coded identification. The 12 mm length supports secure insertion into terminal blocks and reduces the risk of stray strands. Being supplied in a large pack of 500 makes them convenient for repetitive installation work and reduces the need for frequent restocking.
Suitable for
 Crimping 1.5 mm² solid or stranded conductors for terminal connections
 Wiring and maintenance of control cabinets and electrical distribution panels
 Industrial automation, switchgear and machine wiring applications
 Colour-coded identification and neat termination in panel assemblies
When it may not be suitable
These ferrules are sized specifically for 1.5 mm² conductors; they are not suitable for larger or significantly smaller conductor cross-sections. They are intended for crimp termination and not for soldering applications or high-temperature environments that exceed the material limits of copper or polypropylene.
Key specifications
 Conductor cross-section: 1.5 mm²
 Ferrule length: 12 mm
 Conductor material: copper sleeve
 Insulation material: polypropylene (PP), red
 Pack quantity: 500 pieces
How to use
Strip the conductor to the appropriate length, insert the conductor strands fully into the copper sleeve, and apply a suitable crimping tool that matches the ferrule dimensions. After crimping, check that the insulation collar sits flush with the terminal and that no stray strands are visible. Insert the crimped ferrule into the terminal and tighten the screw or clamp according to the terminal manufacturer’s torque specifications.
What to consider before purchase
 Confirm the conductor cross-section is 1.5 mm² to ensure compatibility.
 Ensure the 12 mm ferrule length suits your terminal depth and wiring layout.
 Verify the red polypropylene insulation meets your colour-coding or temperature requirements.
 Consider pack size (500) relative to project scale and storage.
Usage recommendations
Use a matched die crimping tool for consistent mechanical and electrical connection. Store the ferrules in a dry environment to avoid contamination and verify crimps visually and, when required, with pull tests to ensure reliable terminations in control cabinets and panel work.
