## Long description

The Rittal 4051.725 wire end ferrules are high-quality components engineered for the secure and reliable termination of 2.5 mm² conductors. These ferrules feature a 12 mm sleeve length and a durable grey polypropylene collar, providing essential protection against wire fraying while ensuring a stable and long-lasting electrical connection. Designed for precision, these ferrules facilitate efficient installation in various electrical systems and control cabinets, maintaining consistent performance under standard operating conditions.
Advantages
Using these Rittal wire end ferrules significantly improves the integrity of electrical connections by preventing individual wire strands from spreading or breaking. The integrated polypropylene collar provides additional strain relief and insulation, which enhances safety and simplifies the insertion process into terminal blocks. With a pack size of 500 pieces, these ferrules offer a cost-effective and reliable solution for large-scale wiring projects, ensuring that every connection meets professional standards for conductivity and mechanical stability.
Suitable for
Control cabinet wiring
Industrial electrical installations
Connection of flexible conductors to terminal blocks
Maintenance and repair of electrical equipment
When it may not be suitable
These ferrules are specifically designed for 2.5 mm² conductors and are not suitable for wires with different cross-sections, as an improper fit can lead to poor electrical contact or mechanical failure. They are also not intended for use in environments requiring specialized high-temperature or chemical-resistant materials beyond the standard polypropylene specifications.
Key specifications
Conductor cross-section: 2.5 mm²
Sleeve length: 12 mm
Collar material: Polypropylene (PP)
Colour: Grey
Diameter: 4.2 mm
Quantity: 500 pieces
How to use
To use the Rittal wire end ferrules, first strip the insulation from the end of the 2.5 mm² conductor to a length corresponding to the sleeve. Insert the exposed wire strands fully into the metal sleeve of the ferrule. Use a professional-grade crimping tool designed for wire end ferrules to compress the sleeve securely onto the conductor. Ensure that the crimp is uniform and that the polypropylene collar is positioned correctly against the wire insulation for optimal protection.
What to consider before purchase
Verify that your conductor cross-section is exactly 2.5 mm².
Ensure your crimping tool is compatible with 12 mm sleeve lengths.
Check the required colour coding standards for your specific project.
Usage recommendations: Always use a calibrated crimping tool to ensure a gas-tight connection. Avoid reusing ferrules once they have been crimped, as the mechanical deformation is permanent and will not provide a secure connection if reapplied.
