## Summary description

Rittal AS 4050.771 are insulated ferrules with copper conductor sleeve and polypropylene (PP) insulation designed for 1.0 mm² conductors. Each ferrule has a 12 mm length and 3 mm outer diameter; the pack contains 500 pieces in yellow. They provide reliable crimped terminations for stranded wires in control cabinets, panels and electrical installations.

## Long description

Rittal AS 4050.771 insulated ferrules are crimp end sleeves with a copper conductor sleeve and polypropylene (PP) insulation, designed for use with 1.0 mm² stranded conductors. Each ferrule measures 12 mm in length with an outer diameter of 3 mm and features a plastic collar for secure insertion and reliable mechanical protection. The pack contains 500 yellow ferrules suitable for electrical panels, control cabinets and general wiring where consistent, low-resistance terminations are required.
Advantages
These ferrules combine a tinned copper sleeve for good conductivity and corrosion resistance with a PP insulated collar that supports strain relief and insulation integrity. The uniform dimensions (12 mm length, 3 mm diameter) enable repeatable crimping results with compatible tools, while the plastic collar improves handling and simplifies insertion into terminal blocks. Supplied in a pack of 500, they support medium- to large-volume assembly tasks and reduce the need for frequent reordering.
Suitable for
Crimping onto 1.0 mm² stranded copper conductors
Terminations in control cabinets and switchgear
Wiring in industrial panels and electrical distribution blocks
Applications requiring color-coded ferrules for identification
When it may not be suitable
These ferrules are specifically sized for 1.0 mm² conductors; they are not appropriate for larger or smaller conductor cross-sections and will not provide proper crimping or electrical contact if used outside their intended range. They are intended for copper conductors and are not designed for direct connection to grounding systems that require specialized grounding terminals.
Key specifications
Conductor cross-section: 1.0 mm²
Sleeve material: copper (tinned)
Insulation material: polypropylene (PP) with plastic collar
Length: 12 mm
Outer diameter: 3 mm
Color: yellow
Quantity per pack: 500 pieces
How to use
Strip the stranded conductor to the appropriate length so that the bare wires fully enter the copper sleeve without exposing insulation. Insert the conductor into the ferrule until the insulation meets the plastic collar. Use a suitable insulated ferrule crimping tool sized for 1.0 mm² ferrules and perform a single, firm crimp to compress the sleeve around the conductor. After crimping, verify mechanical retention and electrical continuity before final installation into terminal blocks or connectors.
What to consider before purchase
Ensure conductor cross-section matches 1.0 mm²
Confirm compatibility of your crimping tool with insulated ferrules of 12 mm length
Verify that color-coding (yellow) matches your identification scheme
Check whether tinned copper sleeves meet your corrosion-resistance requirements
Usage recommendations
For consistent results, use a calibrated ferrule crimper suited to insulated ferrules and inspect a sample crimp for correct compression and conductor retention. Store the ferrules in a dry environment to prevent contamination of contact surfaces and follow applicable installation standards for wiring and terminal connections.
