Description
GFBFG4-D-105E High Voltage Energy Storage Fuse | 1500V DC 400A–2000A ESS Fuse
Full Product Description
The GFBFG4-D-105E is a professional high‑power DC energy storage fuse designed specifically for 1500V ESS (Energy Storage System) applications. Covering a wide current range from 400A to 2000A, it delivers ultra‑high breaking capacity up to 250kA at 1500V DC (L/R ≤5ms), providing reliable short‑circuit and overload protection for large‑scale battery energy storage systems, power conversion systems (PCS), battery clusters, and industrial DC power equipment.
Built with advanced ceramic housing and high‑conductivity copper components, this fuse ensures stable performance under extreme conditions. It complies with UL248-13, CE, RoHS, and REACH standards, making it suitable for global grid‑scale and industrial energy storage projects.
