## Summary description

Rittal AS 4051.622 ferrules for insulated wire terminations, made of copper with polypropylene insulation. Designed for 1.5 mm² conductors, 10 mm length and 3.5 mm diameter. Supplied in a pack of 500, these crimp/bootlace ferrules ensure reliable conductor connection, improved contact surface and protection against strand fraying in control cabinets and wiring harnesses.

## Long description

Rittal AS 4051.622 terminal ferrules are insulated crimp/bootlace end sleeves designed for 1.5 mm² conductors. Each ferrule features a copper tubular body for reliable electrical contact and a polypropylene insulating collar for strain relief and identification. The ferrules are 10 mm long with a 3.5 mm outer diameter at the insulated end and are supplied in a pack of 500, suitable for bulk wiring work in control cabinets, distribution blocks and wiring harnesses.
Advantages
These ferrules improve conductor contact area and prevent strand fraying, which helps ensure consistent crimping quality and more reliable electrical connections. The combination of a copper sleeve with a polypropylene collar provides corrosion-resistant conductivity together with mechanical insulation and easier insertion into terminal blocks. The 10 mm length gives sufficient barrel for secure crimping of 1.5 mm² conductors while the packed quantity supports larger installation projects and repetitive tasks.
Suitable for
Crimp termination of stranded copper conductors with a cross-section of 1.5 mm²
Wiring and assembly inside control cabinets and switchgear
Distribution blocks, terminal strips and screw terminal connections
Pre-assembly of wiring harnesses and mass termination tasks
When it may not be suitable
These ferrules are intended for stranded copper conductors of 1.5 mm² and may not be appropriate for solid conductors, significantly larger or smaller cross-sections, or non-copper conductors. They are not designed for direct soldered joints or applications requiring heat-resistant insulation beyond polypropylene characteristics.
Key specifications
Conductor cross-section: 1.5 mm²
Body material: copper tubular sleeve
Insulation material: polypropylene plastic collar
Barrel length: 10 mm
Insulated end diameter: 3.5 mm
Pack quantity: 500 pieces
How to use
Strip the conductor to the appropriate length so that the bare strands fully enter the copper barrel. Insert the stranded conductor into the ferrule until the insulation collar seats against the wire insulation. Use a compatible crimping tool sized for 1.5 mm² ferrules and perform a controlled crimp to compress the copper sleeve onto the strands. After crimping, check that the assembly is secure and that the collar provides insulation and strain relief; then insert the ferrule into the terminal and tighten the terminal screw to the specified torque for the application.
What to consider before purchase
Verify conductor type and strand size — these ferrules are for stranded copper conductors of 1.5 mm²
Confirm insulation material and temperature limits of polypropylene meet your operating environment
Ensure you have a compatible crimping tool and die for 1.5 mm² ferrules
Check required quantity and packaging for your installation to avoid shortages
Usage recommendations
For reliable terminations, use a certified crimping tool appropriate for insulated ferrules, strip the conductor to the correct length, and apply the recommended terminal torque. Store the ferrules in a dry environment to avoid contamination and ensure consistent crimp quality across the pack of 500.
