Important Technical Notes:
- Under 20kA short‑circuit test condition, this fuse reduces melting & arcing energy for faster breaking, less impact to power semiconductors.
- Overload threshold & voltage drop remain stable; long‑term current‑carrying capacity is not affected by short‑circuit level.
- Suitable for low‑voltage DC busbar, ESS auxiliary circuit and industrial DC equipment protection.
- Design Tip: Reserve protection margin during selection. Total clearing I²t must be lower than semiconductor device withstand I²t limit.
