Terminating a 10 mm² stranded wire directly into a screw terminal is a common source of connection failure. The fine copper strands can splay out under pressure, creating a high-resistance path that leads to overheating and eventual failure. The QUADRIOS 22C432 solves this problem by bundling all strands into a solid, uniform pin.

This ferrule features a tin-plated copper barrel that, when crimped, provides a gas-tight connection. The red polyamide insulation collar serves two critical functions: it prevents the ferrule from being inserted too deeply into the terminal block, and its color provides immediate visual identification of the wire gauge, following the DIN 46228-4 color code for 10 mm² conductors.

Use these ferrules in high-power applications such as main distribution blocks, motor feeders, industrial power supplies, and large control cabinets. The 12mm pin length ensures full engagement with standard heavy-duty terminal blocks. For a reliable crimp, always use a ratcheting crimping tool with a die specifically designed for 10 mm² ferrules.
