SNEC PV & ESS Expo 2026

As the energy transition accelerates, large-scale Battery Energy Storage Systems (BESS) are becoming essential to stabilizing grids and integrating renewable energy. Increasing battery cell capacities—now reaching beyond 700Ah—are raising new challenges for system protection.

The D123 1500VDC Battery Protection Fuse to address these requirements

Purpose-built for utility-scale ESS, this fuse ensures robust and reliable protection:

• Up to 300 kA breaking capacity for high-energy fault scenarios
• Designed for DC short-circuit protection in large battery systems
• Optimized coordination with contactors
• Proven cycling performance supporting long system lifetime

This solution helps ensure safer, more resilient storage infrastructure at scale.

The rapid expansion of artificial intelligence is reshaping data center design. Higher chip power densities are accelerating the transition to liquid cooling, while advanced electrical protection becomes critical in high-density power architectures.
