About Etigroup
Etigroup (ETI) is a manufacturer of innovative switches, circuit breakers and circuit protection devices for the protection of electrical installations. The product portfolio comprises protection switches and disconnectors (ETIBREAK, ETIPOWER), modular overcurrent and residual current protection devices (ASTI, ETIMAT), contactors and motor protection switches (ETICON), switches, automation and measuring devices, fuses (NH, D, D0, C, medium voltage), surge protection (ETITEC), installation distribution boards and enclosures (ETIBOX), industrial plugs, e-mobility charging stations (ETICHARGE), busbar systems, transformers as well as plastics and technical ceramics products. Production is partly automated: in a specially developed assembly and welding line (with Titus Technologies), magnetic systems for residual current relays made of copper foil, yokes and magnets are assembled in a 4-second cycle, laser-welded and 100 % inspected inline. Etigroup supplies markets across Europe, with website versions for Germany, Poland, the Czech Republic, Ukraine and South-East Europe, among others. Production is focused in Slovenia.
