WATTSTUNDE® Ferrule 4 mm² black 25 pcs.

WATTSTUNDE® Ferrule 4 mm² black – 25 pieces

The WATTSTUNDE® ferrule in 4 mm² offers you a stable, durable, and neatly processable solution for strong fine-stranded conductors. With its robust copper construction, high-quality tin plating, and increased material thickness, it is perfect for demanding electrical installations – whether in solar systems, on caravans, in workshops, or in your DIY projects.

Clean & resilient wire terminations

Especially for conductors with larger cross-sections, a precise and secure termination is crucial. The ferrule prevents the individual strands from fraying, ensures easy crimping, and guarantees a permanently reliable electrical connection. The tinned surface also protects against corrosion – ideal for environments where moisture or heavy loads occur.

Technical details at a glance

• Conductor cross-section: 4.0 mm²
• Length (L): 19.4 mm
• Width (B): 7.4 mm
• d2 (inner diameter): 2.8 mm
• F (sleeve length): 12.0 mm
• d: 4.5 mm
• D: 3.2 mm
• Material thickness: 0.14 mm

Robust material & reliable coating

The ferrule is made of high-quality copper, known for its excellent electrical conductivity. The tin coating protects against oxidation and facilitates the insertion of the wire as well as the crimping process. The increased material thickness of 0.14 mm provides additional stability – an important advantage, especially for thicker conductors.
