DPX³ MCCBs
The new DPX3 630 and 1600 circuit breakers extend the benefits of the DPX3 range up to 1600 A. Not only do DPX3 circuit breakers provide precise, reliable protection, they also include numerous benefits for your low voltage distribution boards.
THE NEW DPX³ HP
125 HP/160 HP/250 HP/630 & 1600
With DPX³ 125 HP, 160 HP and 250 HP, which have been added to the DPX³ 630 and 1600 MCCBs and isolating switches, Legrand offers a solution ideally suited to the performance requirements of all your installations for current ratings from 16 A to 1600 A and breaking capacities up to 100 kA. Quality, reliability and strength are the main attributes of this new range.
Optimised integration: The dimensions of 4P DPX³ 125 HP, 160 HP or 250 HP circuit breakers with or without integrated residual current protection are exactly the same (within the same family), which saves a significant amount of space in enclosures and gives the ability to upgrade the installation from a standard version to a version with integrated residual current protection without changing the wiring or fixing plates.
Quality, reliability and strength
A longer service life for your installations
The Active breaking capacity patented system reduces the current magnitude and dissipated energy in the event of short-circuits, increasing the limitation capacity of devices.
Integrated measurement and optimum continuity of service
With electronic DPX³ 250 HP, 630 and 1600 S10 with integrated measurement, it is very easy to monitor the parameters and consumption of the different circuits in the installation.
Supply inversion and motor operators from 16 to 1600 A
The interlocking device for DPX³ HP greatly simplifies the installation of a supply inverter: It consists of a plate and a mechanical interlocking device.
Reliable protection and accurate measurement up to 1600 A
Suitable for all types of site, the DPX³ range includes 4 sizes of MCCB, for ratings between 16 A and 1600 A and breaking capacities ranging from 16 to 100 kA.
It also offers a wide choice of versions to suit all requirements:
- Thermal-magnetic or electronic releases according to the required level of protection
- Fixed, draw-out and plug-in devices according to the required level of maintenance
- RCBOs
Integrated measurement: the choice of a more compact solution
With electronic DPX³ circuit breakers from 40 A to 1600 A with integrated measurement, it is very easy to monitor the parameters and consumption of the different circuits in the installation, without additional devices or accessories.
The values measured can be viewed:
- Directly in the distribution board, on the LCD screen on the front of the device
- Remotely from a PC or smartphone equipped with supervision software, via the RS485 communication interface and Modbus protocol
Total selectivity for maximum continuity of service
Guaranteeing continuity of service, selectivity between Legrand circuit breakers is optimal thanks to the improved performance of DPX³ devices. Various selectivity techniques can be used.
In critical configurations, the dynamic selectivity and logical selectivity offered by the protection units in electronic DPX³ circuit breakers ensure maximum continuity of service.
Safety, simplicity and speed of installation
With motorised controls and the Legrand automatic control unit, DPX³ transfer switches can be servo-controlled remotely.
Optimal installation & configuration
The multitude of possibilities offered by the many DPX³ auxiliaries and accessories mean they can be adapted to any installation and any electrical board configuration and simplify use and maintenance.
Perfect synergy with Legrand XL³ enclosures is the final piece of the jigsaw when it comes to simplifying implementation!
