History
ABL SURSUM has made a key contribution to the history of electrical installation.
It all began in the Twenties, when the founder of ABL, Albert Büttner, developed the basic idea of the earthed plug and socket system known as SCHUKO (Continental Europe style), which is now one of the most commonly used systems in the world. SURSUM designed the first screw-in circuit breaker with electromagnetic tripping and became a leading manufacturer of circuit breakers.
These were just two in a series of major developments that were to follow. The merger of these two successful specialists in 1986 made it possible to supply a seamless range of products – all from the same supplier.
Today ABL SURSUM is a very successful company, both nationally and internationally, with about 50 per cent of its turnover coming from exports.
