## Summary description

Rittal AS 4050.775 crimp ferrules with copper conductor and red polypropylene (PP) insulated sleeve. Each ferrule measures 12 mm length and 3.5 mm diameter and is supplied in a pack of 500. Designed to provide reliable, corrosion-resistant wire end termination for stranded conductors, improve cable connection consistency, and simplify screw terminal insertion in electrical panels and control cabinets.

## Long description

Rittal AS 4050.775 crimp ferrules are copper conductor end sleeves with a red polypropylene (PP) insulated collar. Each ferrule is 12 mm long with a 3.5 mm outer diameter and is supplied in a pack of 500. These ferrules are engineered to provide a corrosion-resistant termination for stranded conductors, ensure consistent conductor insertion into screw terminals, and simplify reliable connections in electrical panels and control cabinets.
Advantages
These crimp ferrules combine a copper barrel for excellent electrical conductivity with a polypropylene insulated sleeve for mechanical protection and easy identification. The uniform barrel and insulation dimensions support consistent crimping quality and stable contact pressure under screw terminals. Supplied in a bulk pack of 500, they reduce handling time on installation sites and are suitable for repeated use across larger wiring projects.
Suitable for
Termination of stranded copper conductors in control cabinets and distribution panels
Use with screw-type terminals, terminal blocks and relays
Industrial and commercial electrical installations requiring consistent crimp quality
Projects where color-coding of conductor ends simplifies identification and maintenance
When it may not be suitable
These ferrules are intended for use with stranded copper conductors and screw-type terminations; they are not appropriate for solid conductors that do not require end sleeves. They are intended for low-voltage electrical connections and not for applications requiring specialized high-temperature, high-voltage, or exotic material terminations.
Key specifications
Barrel material: copper for low electrical resistance and good corrosion resistance
Insulation material: red polypropylene (PP) collar for mechanical protection and identification
Overall length: 12 mm
Outer 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 stripped stranded conductor into the ferrule until the insulation collar seats against the wire insulation. Use a suitable crimping tool matched to the ferrule size to compress the copper barrel evenly, creating a solid mechanical and electrical joint. After crimping, insert the ferrule into the screw terminal and tighten the terminal screw to the manufacturer's recommended torque.
What to consider before purchase
Confirm compatibility with the conductor cross-section and the terminal type to ensure proper fit and contact
Verify that the 12 mm length and 3.5 mm diameter match your crimping tool and terminal dimensions
Consider the red insulation color for your color-coding scheme and maintenance requirements
Ensure the pack size of 500 suits the scale of your installation to avoid excess inventory
Usage recommendations
Use a calibrated crimping tool sized for these ferrules and apply the recommended terminal torque after crimping. Inspect a sample of crimped connections for proper compression and absence of loose strands before completing the installation.
