Description

 

GFBFG4-S-105E Energy Storage Fuse Link 1500V DC 400A–2000A for ESS

Full Product Description

The GFBFG4-S-105E is a high-performance energy storage dedicated fuse link designed for 1500V DC ESS (Energy Storage System) applications. It covers a current range from 400A to 2000A and provides ultra-high breaking capacity up to 250kA @1500V DC with a time constant L/R ≤5ms.
This fuse link adopts advanced aR semiconductor protection characteristics, featuring fast fault interruption, high current-limiting performance, low power loss, and excellent thermal stability. It is widely used in large-scale battery energy storage systems, power conversion systems (PCS), battery clusters, energy storage cabinets, and high-power DC power distribution equipment.
The fuse link uses high-strength flame-retardant ceramic tube and high-purity copper conductors, ensuring stable performance under extreme working conditions. It complies with UL248-13, IEC60269, CE, RoHS and other international standards, making it ideal for global grid energy storage, industrial energy storage, and new energy projects.
