description: "Schneider Electric's study on 800 VDC data center arc flash risks indicates that incident energy is often manageable and comparable to AC systems. Simulations of hyperscaler-aligned designs show rack-level sidecar configurations can stay below PPE thresholds without protection, while centralized designs require overcurrent protection to match AC safety levels."

# Schneider Electric study finds 800 VDC data center arc flash risk manageable, often comparable to AC systems

-   Schneider Electric published an arc-flash risk analysis for 800 VDC power architectures used in AI data centers. \* Study modeled two hyperscaler-aligned designs, finding risk depends on architecture, capacitor placement, fault-clearing speed. \* Simulations indicated incident energy can be manageable, often comparable to typical AC systems under conservative capacitor-dominated assumptions. \* Rack-level 800 VDC sidecar design showed incident energy below the 1.2 cal/cm² PPE threshold, even without protection devices. \* Centralized facility-level designs showed higher potential without overcurrent protection, but standard protection reduced energy to common AC-aligned levels.
