NSE AG – Protection and Control Technology for the Energy Future

NSE AG has been developing and manufacturing innovative protection and control devices for medium- and high-voltage networks for over 25 years.
Our solutions ensure reliable, standards-compliant protection of power distribution systems operating at voltage levels from 10 to 110 kV – ranging from industrial facilities and renewable energy plants to critical infrastructures such as urban grids, railway power systems, and substations.
The KOMBISAVE+ and POWERSAVE product families provide comprehensive grid protection solutions for a wide variety of applications.
They combine overcurrent, distance, and differential protection with integrated bay control, powerful communication via IEC 61850, and optional power management functions for blackout-resilient and future-proof power networks.
Their modular design allows flexible adaptation to project-specific requirements.
The DIGICOM engineering and parameterization software enables efficient device configuration, seamless system integration, and in-depth analysis of operational and disturbance data throughout the entire system lifecycle.
Pure and Simple Technology represents NSE AG’s commitment to sustainable, robust, and future-ready products—engineered with a strong focus on reliability, ease of use, and long-term investment security.
