The ABB E4.2 series of frame circuit breakers is a star product in the Emax 2 family, designed specifically for high demand power systems. Its core advantages mainly focus on four aspects:

Firstly, it has high current carrying capacity and extremely high breaking capacity. The E4.2 series supports a rated current of 4000A, meeting the needs of large industrial equipment and distribution systems, especially suitable for key scenarios such as power plants and data centers. The rated short-circuit breaking capacity is as high as 42kA to 200kA, which can quickly cut off the fault current, prevent equipment damage and system failure.

The second point is its compact design, which saves space. By optimizing the layout and cross-sectional area of the busbar, the E4.2 series significantly reduces the installation space of the switchgear.

The third point is intelligent protection and convenient maintenance. The entire series adopts standardized protection release devices and auxiliary modules, simplifying the design and installation process and reducing the complexity of operation and maintenance. It also supports the integration of remote communication modules, real-time monitoring of parameters such as current and voltage, achieving fault warning and remote control, and improving system management efficiency.

Finally, there is full selective protection, which can achieve complete selectivity in complex power grids through precise overload and short-circuit protection mechanisms, isolating only the fault area and minimizing the scope of power outages.

The E4.2 series has a wide range of applications, providing stable power support for heavy machinery and production lines in industrial power distribution systems, and preventing overload risks. Protect key equipment such as transformers and generators in energy infrastructure. Ensure uninterrupted power supply through high reliability in commercial buildings and data centers to reduce downtime losses.

As a global leader in electrical technology, ABB has injected a century of innovation into the E4.2 series, redefining the benchmark for power protection. I have posted some popular and advantageous models below. Bosses in need can contact me!
