Air circuit breakers up to 6300 A




The range covers:
- 8 rated currents, between 800 A and 6 300 A.
- 3 breaking capacities 50 kA, 65 kA and 100 kA.

DMX³ air circuit breakers and DMX³-I isolating switches are available in two frame sizes, in fixed and draw-out version.


The overall dimensions of the breaker contribute considerably to an efficient use of the space inside the electrical panel. The constant depth for all the rated currents facilitates connection of the busbars.
