WAGO 221 series lever-nut connectors

The WAGO 221 series is a revolutionary line of lever-nut connectors designed for electrical installations. Unlike traditional twist-on wire nuts, these connectors utilize a lever mechanism to secure wires, allowing for tool-free, reusable, and secure connections for solid, stranded, and fine-stranded wires.

Founded in Minden, Germany, WAGO has been a pioneer in spring pressure connection technology since the 1950s. While their primary manufacturing and engineering hub remains in Germany, the company operates global production sites in Switzerland, Poland, China, India, and the United States to meet international demand.

WAGO remains a family-owned business, maintaining its headquarters in Minden. The brand is synonymous with high-quality electrical components and continues to lead the market in terminal block and connector innovation, ensuring safety and efficiency for electricians worldwide.
