Supplied in a pack of 50 pieces, it is widely used in electrical installations, control panels, and industrial wiring applications.

## Long description

The Erko TE\_25-18/50 tinned wire end ferrule is an essential electrical accessory designed for the secure and reliable termination of flexible stranded copper conductors with a nominal cross-section of 25mm2. Manufactured from high-quality electrolytic copper and finished with a protective tin-plated layer to prevent oxidation, this professional component guarantees optimal electrical contact and mechanical stability when connecting wires to terminal blocks, circuit breakers, and screw clamp connections. Supplied in a convenient pack of 50 pieces, these wire end ferrules help prevent individual wire strands from fraying or breaking, ensuring a neat and safe installation in control panels, switchboards, and various industrial wiring systems.
Advantages
Using the Erko TE\_25-18/50 tinned wire end ferrule significantly improves the safety and longevity of electrical connections by bundling all fine strands of a flexible conductor together. The electrolytic copper material offers excellent electrical conductivity, minimizing resistance and heat generation during operation. Additionally, the protective tin-plated finish effectively guards the metal against corrosion and oxidation, even in demanding environments. This results in a consistently reliable connection that maintains its integrity over time, making installation faster and easier for professional electricians and technicians working with stranded cables.
Suitable for
Electrical installations requiring secure termination of 25mm2 flexible stranded copper conductors
Control panel wiring and industrial switchboard assembly
Connecting power cables to terminal blocks and screw clamp devices
Preventing conductor fraying in multi-strand wire applications
When it may not be suitable
This wire end ferrule is not designed for solid core wires, as solid conductors do not require stranding protection and generally connect directly to terminals. It is also unsuitable for conductors with cross-sections significantly different from the specified 25mm2 size, as an improper fit can lead to loose connections or installation difficulties.
Key specifications
Conductor cross-section compatibility: 25mm2
Material composition: Electrolytic copper
Surface finish: Tin-plated for oxidation protection
Quantity per package: 50 pieces
Application type: Termination of flexible stranded copper conductors
How to use
To use the Erko TE\_25-18/50 tinned wire end ferrule correctly, first strip the insulation from the end of the flexible copper conductor to match the length of the metal tube. Carefully twist the exposed wire strands slightly to ensure they are aligned, then insert the stripped conductor fully into the tubular opening of the ferrule until the insulation touches the plastic or edge of the collar. Use a properly calibrated crimping tool designed for wire end ferrules to compress the metal sleeve securely onto the conductor strands. Once crimped, the finished wire can be safely inserted into the corresponding terminal block, circuit breaker, or screw clamp connection and tightened to the manufacturer's recommended torque.
What to consider before purchase
Verify that the conductor cross-section of your wiring matches the 25mm2 specification
Ensure you have a suitable crimping tool compatible with this ferrule size
Check the terminal block capacity to ensure the crimped ferrule will fit correctly
Always use a correctly calibrated crimping tool matching the ferrule size to ensure a secure mechanical and electrical connection, and disconnect the power supply before performing any electrical installation work.
