WATTSTUNDE® Ferrule 4 mm² Black – 25 Pieces

The WATTSTUNDE® ferrule in 4 mm² offers a stable, durable, and cleanly processable solution for strong fine-stranded conductors. With its robust copper construction, high-quality tin coating, 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 Conductor Terminations

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

Technical Details at a Glance
