## Summary description

Rittal AS 4050.776 is a pack of 500 insulated cable ferrules designed for terminating 1.5 mm² conductors. Each ferrule has a copper inner sleeve with a polypropylene (PP) insulating collar in red, 18 mm length and 3.5 mm outer diameter. Suitable for safe, reliable crimp connections in control cabinets, distribution blocks and general electrical installations.

## Long description

Rittal AS 4050.776 insulated cable ferrules are supplied as a pack of 500 and are designed for reliable termination of 1.5 mm² conductors. Each ferrule combines a copper inner sleeve for good electrical conductivity with a polypropylene (PP) insulating collar in red, giving an overall length of 18 mm and an outer diameter of 3.5 mm. These ferrules are intended for use where consistent crimped connections are required, such as in control cabinets, distribution blocks and general electrical installations.
Advantages
These ferrules provide a conductive copper sleeve that ensures low-resistance connections and consistent contact area when crimped. The polypropylene insulating collar offers mechanical support and color coding for easy identification. Supplied in a bulk pack of 500, they simplify inventory management for maintenance and installation tasks and reduce the time needed to prepare multiple terminations.
Suitable for (tasks / use cases)
Terminating single-core copper conductors with a cross-section of 1.5 mm²
Crimp connections in control cabinets and switchgear
Distribution blocks, terminal strips and relay connections
Electrical installations in commercial and industrial environments
When it may not be suitable
These ferrules are specifically sized for 1.5 mm² single-core conductors; they are not appropriate for larger or smaller conductor cross-sections. They are intended for copper conductors and should not be used with aluminum conductors without appropriate transition measures. The polypropylene collar provides basic insulation and identification but does not replace heat-shrink tubing or additional environmental protection where moisture, chemicals or extreme temperatures are present.
Key specifications
Conductor cross-section: 1.5 mm²
Inner sleeve material: copper
Insulation collar material: polypropylene (PP), red
Overall length: 18 mm
Outer diameter: 3.5 mm
Pack quantity: 500 pieces
How to use
Strip the conductor insulation to the appropriate length so the bare conductor can fully enter the copper sleeve. Insert the conductor into the ferrule until the collar meets the wire insulation. Use a properly sized ferrule crimping tool to compress the copper sleeve uniformly, producing a reliable, gas-tight connection. After crimping, verify mechanical retention and electrical continuity. For panel wiring, push the crimped ferrule into the terminal and secure the terminal screw as required.
What to consider before purchase
Verify conductor cross-section compatibility: 1.5 mm²
Confirm conductors are copper; ferrules are not intended for direct use with aluminum conductors
Ensure the ferrule length and outer diameter fit available terminals and connection points
Consider additional environmental protection if installations are exposed to moisture, chemicals or high temperatures
Usage recommendations
For consistent results use a calibrated crimping tool matched to 1.5 mm² ferrules and follow industry-standard crimping procedures. Store the pack in a dry location to avoid contamination of the copper sleeves and maintain clear labeling to streamline future maintenance.
