## Summary description

Rittal AS 4050.786 terminal ferrules for insulated wire end protection and reliable conductor connection. Constructed with a copper tube and polypropylene (PP) collar in black. Specified diameter 6.3 mm and length 18 mm, supplied as 100 pieces per pack. Suitable for crimping to reinforce stranded conductors and ensure secure screw-terminal contacts in electrical assemblies.

## Long description

Rittal AS 4050.786 terminal ferrules are designed to protect insulated wire ends and create secure conductor connections in electrical assemblies. Each ferrule consists of a copper tube for reliable electrical contact and a polypropylene (PP) collar in black that facilitates handling and crimping. The ferrules have an inner diameter suited for 6.3 mm connections and an overall tube length of 18 mm; they are supplied in packs of 100 for routine installation and maintenance tasks.
Advantages
These terminal ferrules improve the mechanical stability and electrical reliability of stranded conductors by preventing fraying and ensuring consistent contact in screw terminals. The copper sleeve provides low electrical resistance and good conductivity, while the PP collar supports the crimping process and offers color-coded handling. Supplied in a practical pack quantity, they streamline repetitive wiring work and reduce the risk of loose or inconsistent terminations.
Suitable for
Crimp termination of multi-strand flexible conductors requiring reliable screw-terminal contact
Control cabinets, terminal blocks and distribution panels in industrial or commercial equipment
Maintenance, panel building and repetitive wiring tasks where consistent terminations are needed
Applications where a 6.3 mm ferrule diameter and an 18 mm tube length are appropriate
When it may not be suitable
These ferrules are intended for use with stranded copper conductors that match the specified diameter; they are not suitable for solid-core wires where ferrules do not provide benefit. They also are not a substitute for insulated bootlace lugs or large cable terminations designed for high-current bus bars or very large conductor cross-sections.
Key specifications
Material of conductor sleeve: copper
Collar material: polypropylene (PP), black
Nominal ferrule diameter: 6.3 mm
Tube length: 18 mm
Pack quantity: 100 pieces
How to use
Strip the insulation from the stranded conductor to the correct length, insert the conductor fully into the copper tube so strands are contained, then crimp the ferrule using an appropriately sized crimping tool or crimping die for 6.3 mm ferrules. After crimping, check that the collar is seated against the insulation and that the crimp is tight with no loose strands. Insert the ferrule into the screw terminal and tighten the terminal screw to the manufacturer's recommended torque.
What to consider before purchase
Confirm conductor cross-section and strand size compatibility with a 6.3 mm ferrule
Ensure the chosen crimping tool and die match the ferrule dimensions
Verify that the 18 mm tube length provides sufficient insertion depth for your terminal blocks
Consider pack size (100 pieces) relative to project or maintenance needs
Usage recommendations
Use a dedicated crimping tool with matching dies and perform a pull test on sample terminations to verify mechanical integrity. Store ferrules in a dry environment to avoid contamination of contact surfaces prior to installation.
