A complete offer

With different power ratings (from 630 A to 6300 A), breaking capacities (42 kA, 50 kA, 65 kA and 100 kA) and 4 sizes (fixed or draw-out version), DMX³ air circuit breakers and DMX³-I isolating switches offer great flexibility and are suitable for all requirements.

Racks and cooling

The accuracy and simplicity of protection units

MP4 and MP6 electronic protection units allow accurate adjustment of the various limits for current and time delay values. The result is effective protection against electrical failures while ensuring total selectivity with the downstream circuit breakers.

Fitted with batteries, they are used to monitor parameters and memorise data, even if the circuit breaker is de-energised. And thanks to the LCD display, you can monitor the measured current values, view incorrect adjustments and log them.


Control accessories that are easy to install

You can control a DMX³ circuit breaker remotely using its range of accessories: shunt releases, undervoltage releases, motorised controls and closing coils.

All the control accessories simply fit into the circuit breaker, which is specially configured to make insertion easier. Fast connectors can save a considerable amount of time during cabling operations.

Each type of accessory is compatible with its own slot, to prevent errors.


Maximum connection adaptability

All DMX³ circuit breakers (fixed or draw-out) can be equipped with front or rear connection plates which can easily be modified to adapt to any busbar configuration.

This means you can very easily change the connection type to suit your needs: flat, vertical, horizontal, extra-wide connection, etc.
