Gustav Klauke GmbH 47518 electrical terminals insulated wire end ferrules copper tin-plated yellow 6.0 mm² 18mm

The Gustav Klauke GmbH 47518 electrical terminals insulated wire end ferrules are designed to provide secure, reliable, and durable wire termination for various electrical projects. These components ensure that stranded conductors are held firmly in place, preventing frayed wires and ensuring optimal electrical contact. Manufactured by Gustav Klauke GmbH, these ferrules combine high-grade copper with a protective tin plating to resist corrosion and maintain stable conductivity over time. A bright yellow polypropylene insulation collar provides clear visual identification and additional safety at the connection point.

Advantages

Using these insulated wire end ferrules helps prevent strand breakage in screw and clamp terminals, which significantly increases the lifespan and safety of electrical installations. The copper material ensures excellent electrical performance, while the tin plating prevents oxidation and rust in standard operating environments. The integrated polypropylene collar protects against accidental contact and provides reliable strain relief at the insulation transition. With a standardized design and a convenient pack of 100 pieces, these terminals support efficient, repeatable, and professional wiring tasks.

Suitable for

• Professional electrical installations and maintenance tasks
• Wiring management in control cabinets and distribution boxes
• Securing stranded copper wires in screw terminals and clamp connectors
• Industrial and commercial electrical engineering projects

When it may not be suitable

These wire end ferrules are not designed for solid core wires, as solid conductors do not require ferrules for termination. They are also unsuitable for wire cross-sections that do not match the specified 6.0 mm² capacity, and they should not be used in high-temperature environments that exceed the thermal limits of the polypropylene insulation collar.

Key specifications

• Conductor cross-section: 6.0 mm²
• Pin length: 18 mm
• Material: High-quality copper
• Surface plating: Tin-plated
• Insulation collar material: Polypropylene (PP)
• Insulation collar colour: Yellow
• Terminal diameter: 3.5 mm
• Stripping length: 2.6 cm
• Quantity per pack: 100 pieces

How to use

To use the Gustav Klauke GmbH 47518 wire end ferrules, first strip the electrical wire to the recommended stripping length of 2.6 cm to ensure the correct amount of bare copper is exposed. Twist the strands slightly if necessary to prevent stray filaments, then slide the insulated wire end ferrule over the stripped conductor until the wire insulation meets the internal stop of the polypropylene collar. Insert the ferrule into a properly sized crimping tool and apply adequate pressure to deform the metal sleeve securely around the copper strands. Once crimped, the terminated wire can be safely inserted into the target terminal block, screw terminal, or connector.

What to consider before purchase

• Verify that the wire cross-section of your project matches the 6.0 mm² rating of these ferrules
• Check that your existing crimping tool is compatible with 6.0 mm² wire end ferrules
• Ensure the operating environment is within the standard temperature limits for polypropylene insulation
• Confirm the required quantity for your installation, noting that this product is supplied in packs of 100 pieces

Usage recommendations: Always use a calibrated crimping tool designed specifically for wire end ferrules to ensure a secure mechanical and electrical connection. Inspect each crimped connection before energizing the circuit to verify that no stray strands are exposed and that the wire is firmly retained within the terminal.
