Product Features

- A breaking capacity of 12kA up to 32A and 10kA between 40 to 63A.

- Current-limiting scheme: in the event of a short circuit, are able to limit the let-through current to 60%-70% of the rated current.

- The trip mechanism ensures perfect closure every time,thereby considerably improving the performance of these devices and extending their average lifetime.

-The arc extinguishing system: allows the short-circuit currents of very high value to be interrupted extremely rapidly, the remarkable opening speed of contacts opening and the structure of the arcing chamber contribute to extinguishing the arc in the shortest possible time, ensuring reliable protection of short-circuit.

- The internal contact position allows an exact information of the circuit-breaker status: “green”,open contacts;“red”,closed contacts,independently of the toggle position.

- Sealing/locking sealable with 1 mm wire, to prevent unwanted tripping.

- The supply lines of the protected circuit can be connected to either the upper or lower terminals of the circuit-breakers(reversibility of connections).

- The double terminal of these circuit-breakers enables simultaneous connection of cables and busbars.

Full electrical upgrade of BMA House, 135 Macquarie Street Sydney, a heritage listed 12 storey building constructed in 1925. The upgrade required the installation of a new main switch board, replacement and upgrading of the existing main switch board, and replacement of the common area and tenancy distribution boards.



maintenant, grâce a legrand il est possible de remplacer un disjoncteur dans un tableau fonctionnel sans utiliser d’outil et en moins d’une minute.
le retrait des peignes horizontaux de distribution se fait en quelques seconde sur les dnx3 alors que le dévissage-revissage de l’ensemble de la rangée sur un tableau classique, prend énormément de temps (et nécessite un électricien patient !).

4 minutes contre 1 minutes pour le tout automatique contre les anciens modèles a vis
