Supplying Core Electrical Components for the Sehnde Edge Data Center, Germany

March 15, 2025

Project Snapshot

• Location: Hedwig-Kohn-Straße 3, 31319 Sehnde, Hanover Region, Germany
• Facility Type: Edge Data Center
• Investment: €40 million (Jointly backed by Avacon and enviaM Group)
• Capacity: Up to 28,000 servers within a 185 sqm footprint
• Launch Date: March 2025
• Core Electric’s Contribution: Supplying VDE, TÃœV, and CE-certified electrical components for power distribution and safety isolation.

The Background

Located in the Sehnde-Ost industrial area, the Sehnde edge data center is a privately led project built to support the growing digital infrastructure needs of businesses in Lower Saxony. Because edge data centers handle localized, high-speed computing, continuous uptime is critical.

For the facility’s construction and future expansion, the project team needed power distribution components that balanced two requirements: strict cost control and absolute reliability.

KRIPAL worked alongside local power distribution equipment manufacturers to supply the key electrical parts, ensuring all components met rigorous German engineering standards (TÃœV and VDE) while optimizing the procurement budget.

Key Components Supplied

To support the rapid deployment and stable operation of the data center, KRIPAL provided modular, fully certified electrical components for different stages of the power distribution network.

1. Rack-Level Power Distribution (PDUs)

• Miniature Circuit Breakers (MCBs): Sized for compact 19-inch rack-mounted PDUs. These provide precise short-circuit and overload protection, fully complying with DIN VDE/EN IEC standards to keep server branches secure.
• Moulded Case Circuit Breakers (MCCBs): Used for the main incoming and branch distribution lines. We prioritized high-current breaking capacity and proper grading coordination to prevent nuisance tripping across the system.
• AC Contactors & Thermal Overload Relays: Integrated to handle dynamic load management and allow for remote switching, which is essential for the automated operation of an edge facility.

2. Safety Isolation and Maintenance Support

• UKP Series Switch Disconnectors: Visible break, compliant with DIN VDE standards. Used at the incoming side of distribution cabinets and for maintenance isolation, ensuring operator safety.

• Waterproof Circuit Breakers/ Residual Current Protection: IP54+ protection, resistant to humidity and dust in industrial environments, improving long-term availability of outdoor or semi-outdoor distribution boxes.

Supporting Prefabricated Deployment

Speed is a major factor in modern data center construction. Our components are designed to be modular, fitting easily into standard distribution boxes and prefabricated power modules. This approach reduced on-site cabling requirements and helped keep the installation schedule on track.

Summary

Every KRIPAL product supplied for the Sehnde project carries CE, VDE, and TÃœV certifications, ensuring full compliance with the EU Low Voltage Directive and local grid regulations.

The Sehnde edge data center project in Germany is a typical case of collaborative innovation involving private capital, edge computing, and highly reliable power distribution.

Core Electric remains committed to strengthening its presence in the European market, providing fully certified, stable-performance electrical components to support more data centers in achieving efficient and safe power assurance, contributing Chinese expertise to global digital infrastructure.
