170M6415 FUSE 1100A

Product Description

The 170M6415 is an 1100A, 690V AC high-speed HRC fuse from the Eaton Bussmann 170M series, designed for semiconductor protection in heavy industrial power systems.

It belongs to the aR class ultra-fast fuse category, used for protecting sensitive power electronics such as IGBT modules, thyristors, rectifiers, inverters, UPS systems, and large VFD drives. Its very low I²t value ensures fast fault clearing and minimal damage to expensive semiconductor equipment.
