The Sonoff D1-1 inline wire splicing connectors provide a reliable way to join electrical cables without needing specialized tools. This set of 34 gray connectors with orange levers is designed for versatility, accommodating solid, stranded, or annealed copper wires with cross-sections ranging from 0.2 mm² to 4 mm², which covers AWG 28-12 sizes. Built for safety and durability, each unit features a flame-resistant PC insulating shell and internal copper contacts that support a maximum current of 32A at a rated voltage of 250V. The lever-action mechanism allows you to quickly secure connections and reuse the connectors as your wiring needs change, while their modular design means they can be spliced together for more complex configurations. Measuring 9.1 x 39.3 x 14.5 mm and conforming to the IEC 60997-4:2020 standard, these components come organized in a plastic storage box, making them a practical choice for electricians or homeowners handling home wiring projects.
