Installation of SACE Tmax XT
Circuit-breaker The distances given in the table refer to the maximum overall dimensions of the circuit-breakers in the different versions (F/W/P), with terminals and metallic lugs of insulated cables included, for example. When superimposed circuit-breakers are different in size, the larger reference clearance should be con- sidered. Le distanze indicate nella tabella si riferiscono alle dimensioni d'ingombro massime degli interruttori nelle varie esecuzioni (fissa, estraibile, rimovibile), per esempio con terminali e capicorda metallici di cavi isolati inclusi. Quando gli interruttori affiancati hanno dimensioni diverse, va considerata come di- stanza di rispetto per il montaggio sovrapposto la distanza maggiore indicata per i due interruttori. H [mm] Minimum clearance between two superimposed circuit-breakers This section gives the clearances H to meet for superimposed mounting of the SACE Tmax XT circuit- breakers in installations with voltages up to 690Vac. Verify that the bare bars or connection cables do not reduce the recommended clearances. Distanza minima tra due interruttori sovrapposti In questa sezione sono riportate le distanze minime H da rispettare per il montaggio sovrapposto di in- terruttori SACE Tmax XT in impianti con tensioni fino a 690Vac. Verificare che le sbarre nude o i cavi di connessione non riducano le distanze minime raccomandate.

In case of cables with metallic lugs, an insulating screen behind the metallic lugs (on the rear of the cir- cuit-breaker) or high terminal covers is mandatory. I cavi con capicorda metallici richiedono obbligatoriamente uno schermo isolante dietro i capicorda metallici (sul retro dell’interruttore) o copriterminali alti.
