With the invention of the SCHUKO plug, our company founder Albert Büttner set a new standard for electrical connecting devices in 1925. SCHUKO is short for the German 'Schutzkontakt' (protected contact). Because of its circular geometry and two protected contacts, SCHUKO is regarded as especially safe to use in comparison with other electrical connecting device systems.

The success story of Albert Büttner's invention speaks for itself. Today, SCHUKO is the globally most widely used standard for electrical connecting devices.
With the Compact, Original, Hightech, Expert and Professional series our new product programme offers high-quality plugs and connectors for use in harsh conditions. Thanks to innovative technological features and particularly robust and durable materials, ABL plugs and connectors are the first choice for trade, construction and industry.
