We know today’s power grid needs

Maximized uptime, optimized safety, and high energy capabilities are increasingly important for asset managers with power distribution responsibilities. By building on proven Xiria 630 A / 21 kA technology that served the market for more than 20 years, Xiria NGX can meet these challenges.

Xiria NGX is the result of more than 80 years long expertise in switchgear design and innovation, using Eaton’s core technologies: solid insulation, electrical field control, and vacuum technology.

Integrating Eaton’s proven core technologies into the Xiria NGX ensures it is a compact, safe and reliable solution. Designed as a user and environment-friendly product throughout the whole chain from design to dismantling, Xiria NGX’s features are constructed so that the costs for the owner are as low as possible, with no concessions to its quality during its lifetime of more than 40 years.

Smart switchgear solution

Xiria NGX is one of few switchgear platforms currently offering motorized remote control for both the circuit breaker and disconnector. This enables full remote operation of the switchgear including cable earthing. Other smart switchgear solutions are the availability of current and voltage sensors and a comprehensive set of additional options.

The modular design of Xiria NGX enables easy upgrades with CTs, VTs and motorized operation. As Xiria NGX panels up to 24 kV are in the same housing, NGX also offers optimal flexibility to be used in different grids. For example starting with a 12 kV grid before making a future move to 24 kV.
