Minijaturni automatski prekidači

Proizvodi namijenjeni zaštiti vodiča od struja kratkog spoja, preopterećenja (MCB) i zemljospoja (RCCB/RCBO). Instalacijski prekidači MCB su kompaktni elektromehanički uređaji nazivne struje do 63 A namijenjeni zaštiti od preopterećenja i zemljospoja. Ključni su dio bilo kojeg električnog sustava.
