WAGO 221-413 Splicing Connector

The product shown is a WAGO 221 Series 3-way compact splicing connector, a revolutionary tool in electrical installation. Known for its distinct transparent housing and bright orange levers, this specific model (221-413) allows for the connection of up to three conductors without the need for tools. These connectors are widely praised by electricians for their space-saving design, which is roughly 40% smaller than previous generations like the 222 series.

Originally invented by WAGO Kontakttechnik GmbH & Co. KG in Germany, the brand has become synonymous with 'lever-nuts'. The company was a pioneer in spring pressure connection technology, moving away from traditional screw-type terminals. The 221 series specifically is engineered to handle various wire types—solid, stranded, and fine-stranded—while the clear casing provides a safety benefit by allowing installers to visually verify that the wire is fully inserted and correctly stripped.

WAGO is a family-owned company headquartered in Minden, Germany. While a significant portion of their manufacturing remains in Germany and Switzerland, they operate a global production network with factories in China, India, Poland, and the United States to serve international markets. The brand remains the ultimate leader in this niche, maintaining its independence and technological edge through continuous innovation in 'CAGE CLAMP' technology.
