## Summary description

Rittal AS 4051.578 ferrules are copper conductors with polypropylene (PP) insulation, designed for terminating 0.75 mm² wires. Each insulated end sleeve is 10 mm long and intended to improve connection reliability, prevent stranded wire fraying, and enable secure screw-terminal or connector fittings. Pack contains 500 pieces in white color.

## Long description

Rittal AS 4051.578 ferrules are insulated end sleeves designed for terminating 0.75 mm² stranded conductors. Made with a copper inner sleeve and a polypropylene (PP) plastic collar, each ferrule has a 10 mm insulated length to ensure consistent insertion depth and reliable screw-terminal or connector clamping. The pack of 500 white ferrules is intended for professional electrical assembly, control cabinets, and field wiring where neat, secure wire terminations are required.
Advantages
These ferrules combine a conductive copper tube with a durable polypropylene insulation collar to reduce strand fraying, improve contact reliability, and provide clear insulation at the termination point. The 10 mm length supports deeper and more consistent insertion into screw terminals and insulated connectors, while the plastic collar helps guide the ferrule and protect insulation during crimping. A bulk pack of 500 provides a cost-effective supply for repetitive installation tasks.
Suitable for
 Termination of 0.75 mm² multi-stranded copper wires
 Electrical control panels and terminal blocks
 Field wiring and switchgear assembly
 Applications requiring screw terminals or plug-in connectors
When it may not be suitable
These ferrules are specifically sized for 0.75 mm² conductors and are not appropriate for finer or larger conductor cross-sections; using the wrong size can lead to poor contact or damage. They are intended for general electrical terminations and do not provide insulation ratings or chemical resistance beyond standard polypropylene properties, so they may not be suitable for specialized high-temperature or aggressive chemical environments.
Key specifications
 Conductor cross-section: 0.75 mm²
 Material (conductor): copper inner sleeve
 Insulation material: polypropylene (PP) collar
 Insulated length: 10 mm
 Color: white
 Quantity per pack: 500 pieces
How to use
Strip the conductor to the appropriate length so that the bare strands can be fully inserted into the ferrule tube. Insert the stranded conductor into the copper sleeve until the insulation collar is flush with the wire insulation. Use an appropriate crimping tool sized for 0.75 mm² ferrules to apply a single solid crimp, ensuring even compression without deforming the insulation collar. After crimping, check that the ferrule is secure and that no strands protrude; then connect the ferrule to the screw terminal or connector and tighten to the manufacturer’s torque specification.
What to consider before purchase
 Confirm conductor cross-section is 0.75 mm² to ensure correct fit.
 Verify insulation material and length meet installation and clearance requirements.
 Ensure you have a compatible crimping tool for insulated ferrules of this size.
 Consider pack quantity (500 pieces) relative to project needs to avoid excess or shortage.
Usage recommendations
For reliable terminations, use a calibrated crimping tool sized for insulated 0.75 mm² ferrules, strip the conductor to the correct length, and secure terminals to the torque values specified by the equipment manufacturer. Store ferrules in a dry environment away from direct sunlight to preserve polypropylene properties.
