The 2872.0 is a DIN standard insulated ferrule, type HD 1.0/16, used to ensure reliable electrical connections. It is specifically designed for 18 AWG (1.00 mm²) wire and features a red polypropylene insulating sleeve for identification. The ferrule has a total length of 16.0 mm with a 10.0 mm tin-plated copper tube, requiring a corresponding wire stripping length of 10.0 mm. These ferrules prevent conductor breakage from bending or vibration while facilitating wire insertion into terminal blocks, circuit breakers, and other control devices, with their DIN compliance making them ideal for export applications.
