Braided 99.9% copper strap with tinned end tails, 300 mm length and 70 mm² cross-section. Rated up to 400 A and manufactured in line with DIN 72349.
Secure, low-resistance earthing – thanks to 99.9% soft-annealed copper braid
Highly flexible braided strands are soft-annealed to improve grain structure and electrical contact, keeping resistance low across the braid. Tinning on the ends aids consistent metal-to-metal contact.
Consistent, low-resistance connections reduce voltage drop and improve grounding reliability in engine bays and metal chassis.
Durable termination points – with tinned end tails
End tails are tinned to protect the copper from oxidation and to maintain a stable mating surface for bolts or clamps. Tinning helps preserve contact quality under repeated assembly cycles.
Fewer maintenance interventions and more reliable long-term connections where corrosion or exposure is a concern.
Vibration-tolerant installation – with flexible braided construction and short length
Braided construction absorbs movement and flexing, while a 300 mm length keeps runs compact and less prone to chafing. Flexibility reduces stress at fastenings under vibration.
Suitable for engine bays and machinery where movement would otherwise loosen rigid connections.
