Ergom WK 2,5I Insulated Wire End Sleeve 0.25-2.5 mm²

The Ergom WK 2,5I insulated wire end sleeve is a professional-grade component engineered for the secure termination of flexible copper conductors. Designed to accommodate wire cross-sections ranging from 0.25 mm² to 2.5 mm², this sleeve provides a reliable connection point that prevents individual wire strands from fraying or breaking when inserted into terminal blocks, circuit breakers, or other electrical connectors. By consolidating the conductor strands, it ensures optimal electrical conductivity and long-term mechanical stability in various wiring systems.

Advantages

The primary benefit of using the Ergom WK 2,5I sleeve is the significant improvement in connection safety and durability. The integrated insulation collar provides additional strain relief and prevents accidental short circuits between adjacent terminals. Its robust construction ensures that the wire remains firmly in place even under vibration, while the high-quality materials used in its production guarantee resistance to environmental factors. This sleeve simplifies the installation process, allowing for quick and consistent terminations that meet professional electrical standards.

Suitable for

• Industrial control panels and automation systems
• Domestic electrical wiring and distribution boards
• Connecting flexible cables to screw or spring-loaded terminals
• Automotive and marine electrical installations

When it may not be suitable

This product is specifically designed for flexible copper conductors and is not intended for use with solid core wires, as these do not require end sleeves for termination. It should not be used in applications where the wire cross-section exceeds the specified 2.5 mm² limit or falls below 0.25 mm², as this will result in an insecure connection.

Key specifications

• Conductor capacity: 0.25 mm² to 2.5 mm²
• Material: Electrolytic copper with tin plating
• Insulation material: Polypropylene
• Design: Insulated ferrule

How to use

To use the Ergom WK 2,5I sleeve, first strip the insulation from the end of the flexible copper wire to the appropriate length. Insert the exposed wire strands into the metal tube of the sleeve until they reach the end. Using a compatible crimping tool designed for wire end sleeves, apply pressure to the metal portion of the sleeve to create a secure, gas-tight connection. Once crimped, the wire is ready to be inserted into the terminal block and tightened.

What to consider before purchase

• Ensure the wire cross-section matches the sleeve capacity
• Verify that you have a compatible crimping tool for wire end sleeves
• Check the terminal block space to ensure the insulated collar fits correctly

Usage recommendations

Always use a calibrated crimping tool to ensure the integrity of the connection. Avoid reusing sleeves once they have been crimped, as the mechanical properties of the metal are permanently altered during the initial installation.
