SCHUKO electrical connecting devices.
ABL – inventor of the SCHUKO plug
ABL offers a substantial range of plugs, connectors and socket outlets, as well as connecting devices for portable site offices and low-voltage applications.
We have since continued to developed the classic ABL rubber plug further. With innovative technological features and new materials, such as the high performance plastic Elamid, our Hightech and Professional series are the embodiment of contemporary SCHUKO electrical connecting devices.
SCHUKO
The original since 1925
ABL – inventor of
the SCHUKO plug
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.
We have since continued to developed the classic ABL rubber plug further. With innovative technological features and new materials, such as the high performance plastic Elamid, our Hightech and Professional series are the embodiment of contemporary SCHUKO electrical connecting devices.
Professional product series, we use top of the range 2K technology
Thanks to their excellent manufacturing materials, ABL connecting devices from all series are the products of choice in trade, construction and industry. For example, we use the high performance plastic Elamid for our Hightech series. For our SCHUKO Professional product series, we use top of the range 2K technology. This makes ABL plugs and connectors unbeatably tough, and even able to withstand being driven over by a 4-ton vehicle.
All ABL connecting devices are Made in Germany and manufactured at our company headquarters in Lauf.
