Ergom H 50/22 Insulated Wire End Sleeve, 50 mm² Cross-Section, 22 mm Pin Length, 100 Pieces

The Ergom H 50/22 insulated wire end sleeve is a professional-grade component engineered for the secure termination of flexible copper conductors with a cross-section of 50 mm². By providing a clean and organized connection point, this sleeve effectively prevents the fraying of individual wire strands, ensuring long-term electrical integrity and safety in various terminal blocks and connectors. With a pin length of 22 mm, it offers sufficient surface area for robust contact, making it an essential tool for maintaining high-quality electrical connections in demanding environments.

Advantages

The primary benefit of using the Ergom H 50/22 sleeve is the significant improvement in connection reliability. By bundling the fine strands of a flexible conductor, the sleeve minimizes contact resistance and prevents potential short circuits caused by stray wire strands. The integrated insulation provides additional protection against accidental contact and helps to strain-relieve the connection point, which is critical for industrial applications where vibration or mechanical stress may be present. These ferrules are designed for consistent performance, facilitating easier insertion into terminal blocks and ensuring a uniform, professional finish for every wiring project.

Suitable for

• Industrial electrical control panels
• Power distribution systems
• Heavy-duty machinery wiring
• Professional electrical installation projects
• Connecting flexible copper conductors to screw or spring-loaded terminals

This product is not suitable for solid core conductors, as it is specifically designed to manage the strands of flexible wiring. Additionally, it should not be used in applications where the wire cross-section deviates from the specified 50 mm², as an improper fit will compromise the mechanical and electrical integrity of the connection.

Key specifications

• Conductor cross-section: 50 mm²
• Pin length: 22 mm
• Insulation material: Polypropylene
• Contact material: Electrolytic copper, tin-plated
• Quantity: 100 pieces per pack

How to use

To use the Ergom H 50/22 sleeve, first strip the insulation from the end of your 50 mm² flexible copper wire to a length corresponding to the sleeve's pin length. Insert the stripped wire strands fully into the metal tube of the ferrule. Using a professional crimping tool designed for this specific cross-section, apply firm pressure to the sleeve to create a gas-tight mechanical bond between the ferrule and the conductor. Once crimped, the wire is ready to be inserted into the terminal block and secured according to the manufacturer's torque specifications.

What to consider before purchase

• Verify that your wire cross-section is exactly 50 mm².
• Ensure you have a compatible crimping tool capable of handling this size.
• Check the depth of your terminal block to ensure the 22 mm pin length is appropriate.
• Confirm the quantity required for your specific installation project.

Usage recommendations

Always use a calibrated crimping tool to ensure the integrity of the connection. Avoid reusing ferrules once they have been crimped, as the mechanical deformation is permanent and will not provide a secure connection if reapplied.
