WATTSTUNDE® Wire End Ferrule 4 mm² Black – 25 Pieces

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

Clean & durable ladder ends

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