## Summary description

Rittal AS 4051.616 ferrules for stranded conductors, suitable for 0.75 mm² cross-section. Each ferrule has a 10 mm length, 2.8 mm outer diameter, copper tube with polypropylene (PP) insulation and a grey color. Supplied in a pack of 500 pieces, they ensure reliable crimped terminations for panel wiring, control cabinets and electrical installations.

## Long description

Rittal AS 4051.616 ferrules are insulated crimp end sleeves designed for secure terminations of stranded conductors with a nominal cross-section of 0.75 mm². Each ferrule features a 10 mm copper tube and a polypropylene (PP) insulated collar with a 2.8 mm outer diameter. Supplied in a pack of 500, these grey-collared ferrules are intended for reliable, repeatable connections in panel wiring, control cabinets and general electrical installations.
Advantages
These ferrules combine a copper conductor sleeve for good electrical contact with a PP insulated collar that supports insertion into terminals and prevents wire strand fraying. The 10 mm tube length provides adequate conductor insertion depth for secure crimping, while the consistent 2.8 mm outer diameter ensures compatibility with many common terminal types. Supplied in bulk packs of 500, they support larger wiring tasks without frequent restocking.
Suitable for
Crimp terminations on stranded conductors of 0.75 mm² cross-section
Terminal blocks and screw connectors in control cabinets and distribution panels
Field and workshop wiring where standardized insulated ferrules are required
Repeatable terminations in production or maintenance settings
When it may not be suitable
These ferrules are specifically sized for 0.75 mm² conductors; they are not suitable for larger or smaller conductor cross-sections where a different ferrule size would be required for reliable crimping. They are intended for insulated terminations and not designed to replace soldered joints or to serve as an insulation barrier for high-mechanical-stress applications.
Key specifications
Conductor cross-section: 0.75 mm²
Tube length: 10 mm
Outer diameter (collar): 2.8 mm
Tube material: copper
Insulation material: polypropylene (PP)
Color: grey
Pack quantity: 500 pieces
How to use
Strip the conductor to the correct length so that the bare strands fully enter the 10 mm copper tube. Insert the stripped conductor into the ferrule until the insulation of the wire arrives at the PP collar. Use an appropriate crimping tool sized for 0.75 mm² ferrules to compress the copper tube evenly, creating a gas-tight connection between conductor and sleeve. After crimping, check that the ferrule is secure and that no strands protrude. Insert the crimped ferrule into the terminal and tighten the terminal screw to the manufacturer's recommended torque.
What to consider before purchase
Verify conductor cross-section: intended for 0.75 mm² stranded conductors only
Confirm terminal compatibility with a 2.8 mm collar outer diameter
Ensure your crimping tool supports ferrules of this size for consistent results
Consider pack size (500 pieces) relative to project requirements to avoid surplus or shortage
Usage recommendations
For reliable, long-term connections, use a dedicated ferrule crimping tool and follow recommended torque values for terminal screws. Store ferrules in a dry environment to prevent contamination before use, and match ferrule size precisely to conductor cross-section to maintain electrical and mechanical integrity.
