## Summary description

Rittal AS 4051.624 ferrules are insulated wire end sleeves made of copper tube with polypropylene insulation. Designed for 1.5 mm² conductors, 18 mm overall length, they provide reliable crimped connections that improve contact quality and prevent strand fraying. Supplied in a pack of 500 for electrical panel, terminal block and control cabinet wiring.

## Long description

Rittal AS 4051.624 wire ferrules are insulated end sleeves combining a copper tube with polypropylene insulation to terminate 1.5 mm² flexible conductors. Each ferrule measures 18 mm in overall length and is supplied in a pack of 500, intended to improve crimped connections in electrical panels, terminal blocks and control cabinet wiring by securing strands and enhancing contact surface area.
Advantages
These ferrules provide consistent mechanical and electrical connection quality by preventing strand fraying and ensuring reliable crimps. The copper inner sleeve offers low electrical resistance and good conductivity, while the polypropylene collar provides electrical insulation and protects against damage during handling and insertion into terminals. Packaging in a bulk pack of 500 supports efficient installation workflows and reduces interruptions for replenishment.
Suitable for
Termination of flexible and stranded conductors of nominal cross-section 1.5 mm²
Wiring of terminal blocks, distribution boards and control cabinets
Applications requiring repeated, consistent crimp quality in electrical installations
When it may not be suitable
These ferrules are sized specifically for 1.5 mm² conductors and an 18 mm length; they are not suitable for larger or smaller conductor cross-sections or for applications where a different sleeve length is required. They are intended for crimp terminations and not for soldered or welded connections.
Key specifications
Conductor cross-section: 1.5 mm²
Overall length: 18 mm
Inner material: copper tube for electrical conduction
Insulation material: polypropylene collar
Pack quantity: 500 pieces
How to use
Strip the conductor to the appropriate length, insert the stripped strands fully into the copper sleeve so that the insulation collar seats against the wire insulation, and use a suitable ferrule crimping tool sized for 1.5 mm² ferrules to make a single, firm crimp. After crimping, verify that the ferrule is securely attached and that no strands protrude. Insert the terminated conductor into the terminal block or connector and tighten the terminal according to the terminal manufacturer’s torque specification.
What to consider before purchase
Confirm conductor cross-section: suitable for 1.5 mm² only
Verify required sleeve length and panel/terminal depth to ensure proper fit with 18 mm length
Ensure availability of a compatible crimping tool for insulated ferrules of this size
Usage recommendations
Use a dedicated insulated ferrule crimper sized for 1.5 mm² to achieve reliable, repeatable crimps. Check each termination for full insertion and absence of stray strands; follow terminal torque values to ensure optimal electrical contact and mechanical stability.
