Rittal AS 4050.770 Wire End Ferrules, 10 mm Length, 3 mm Diameter, Yellow, 500 Pieces

The Rittal AS 4050.770 wire end ferrules are essential components for creating secure and durable electrical terminations. Engineered for precision, these ferrules feature a high-quality copper core that ensures excellent electrical conductivity, paired with a robust polypropylene (PP) insulation sleeve. The integrated plastic collar provides additional strain relief and protection for the wire insulation, facilitating a clean and reliable connection in various electrical systems.

Advantages

These ferrules offer superior performance by preventing wire fraying and ensuring a consistent contact surface for terminal blocks and connectors. The use of high-grade copper guarantees low contact resistance, while the durable polypropylene collar simplifies the insertion process and enhances safety. The yellow color-coding allows for quick visual identification, which significantly improves efficiency during complex wiring tasks and maintenance procedures.

Suitable for

• Professional electrical panel building
• Industrial automation and control systems
• General electrical installation and wiring
• Maintenance and repair of electrical equipment

When it may not be suitable

These ferrules are designed for specific wire gauges corresponding to a 3 mm diameter. They may not be suitable for applications requiring significantly larger or smaller wire cross-sections. Additionally, they are intended for standard indoor electrical environments and may require specialized protection if used in highly corrosive or extreme temperature conditions.

Key specifications

• Material: Copper with polypropylene (PP) insulation
• Length: 10 mm
• Diameter: 3 mm
• Color: Yellow
• Quantity: 500 pieces per pack
• Design: With plastic collar

How to use

To use the Rittal wire end ferrules, first strip the insulation from the end of your electrical wire to a length matching the ferrule. Insert the stripped conductor into the metal tube of the ferrule until the wire strands are fully contained. Use a compatible crimping tool to compress the metal sleeve onto the wire, ensuring a gas-tight connection. The plastic collar should sit flush against the wire insulation to provide support and prevent accidental contact.

What to consider before purchase

• Verify that the 3 mm diameter matches your specific wire gauge requirements.
• Ensure you have a compatible crimping tool designed for wire end ferrules.
• Check the required length of 10 mm against your terminal block specifications.

Usage recommendations

For optimal results and long-term reliability, always use a calibrated crimping tool that matches the ferrule size. Avoid reusing ferrules once they have been crimped, as the mechanical integrity of the metal sleeve is compromised after the initial deformation.
