## Summary description

Rittal AS 4050.773 is a crimp terminal ferrule with a copper conductor tube and polypropylene (PP) insulation in white. It has a tube length of 8 mm and an outer diameter of 2.8 mm, suitable for reliable wire end termination and crimp connections. Used for secure electrical connections in control cabinets, switchgear and industrial wiring.

## Long description

Rittal AS 4050.773 is a crimp terminal ferrule designed for secure wire-end termination. The part combines a copper conductor tube with a white polypropylene (PP) insulated collar, providing reliable electrical contact and mechanical protection for stranded conductors. Its compact dimensions — an 8 mm tube length and a 2.8 mm outer diameter — make it suitable for tight terminal blocks and dense wiring arrangements commonly found in control cabinets, switchgear and industrial installations.
Advantages
The copper tube enables low-resistance, corrosion-resistant contact suitable for repeated insertion into screw and spring-type terminals. The polypropylene collar simplifies handling during crimping and offers color-coded identification while preventing stray strands from splaying. The small form factor supports neat wiring and consistent crimp quality when used with the appropriate ferrule crimping tool.
Suitable for
Terminating stranded wires for screw and spring-clamp terminals
Wiring inside control cabinets and electrical panels
Industrial and machine wiring where compact ferrules are required
Applications that require color-coded, insulated ferrules for identification
When it may not be suitable
This ferrule is intended for terminating stranded conductors and may not be appropriate for solid wire types or conductors that exceed the ferrule’s dimensional limits. It is a passive crimp accessory and does not provide insulation rated for high-voltage isolation by itself; additional insulation measures may be required depending on application standards.
Key specifications
Conductor tube material: copper
Insulation material: polypropylene (PP), white
Tube length: 8 mm
Outer diameter: 2.8 mm
How to use
Strip the stranded conductor to the appropriate length, insert the conductor into the copper tube until the insulation meets the polypropylene collar, and crimp the ferrule using a suitable insulated ferrule crimping tool sized for the ferrule diameter. Verify the crimped connection for secure mechanical retention and good electrical contact before inserting into the terminal. Follow relevant installation standards and torque specifications for the terminal block used.
What to consider before purchase
Confirm compatibility with the conductor cross-section and strand count used in your wiring
Ensure the 8 mm tube length and 2.8 mm outer diameter fit the target terminal or connector
Choose the correct crimping tool and die set for insulated ferrules of this size
Verify whether color-coded insulation meets your identification or standardization requirements
Usage recommendations
Use the Rittal AS 4050.773 with a matched ferrule crimping tool and check crimps regularly in environments subject to vibration; combine with appropriate terminal covers or additional insulation where required by safety standards.
