DESCRIPTION

Description

The HCBMG5 Series from HIITIO are size 5# ceramic square body DC high-speed fuses with bolted tags. Designed for partial range protection, they deliver high pre-arcing I²t, powerful current limiting, high breaking capacity (250kA @ 1500Vdc), and extremely fast acting performance. These fuses are specifically engineered to protect IGBT modules, battery energy storage systems (BESS), DC common bus, DC drives, power converters, rectifiers, and other critical DC applications.
Standards & Approvals
