The word "cables" may be spanish or english
"Und" is a german word that means "y" in spanish.
"Tracción" y "engastados" are spanish words.
Perhaps "s/"is the abbreviature of "sobre" (upon) or "sin" (without)
Perhaps "min" is the abbreviature of "mínimo" (at least) or "minutos" (minutes)
Perhaps "60N" means 60 newtons.
I guess: ""Cables FLRY-B sobre DIN 72551 y con tracción, engastados con una fuerza mínima de 60 newtons (o con una fuerza de 60 newtons por minuto) sobre DIN 46249"
Sincerely, I have no idea about the meaning of the sentence.
