170M7917 FUSE 125A 660V

Product Description

The 170M7917 fuse is a square-body knife blade HRC fuse designed according to IEC 60269-4 (aR class). It provides extremely fast interruption of short-circuit currents while protecting sensitive equipment such as VFDs, rectifiers, UPS systems, and soft starters.

It uses a sand-filled ceramic body that safely extinguishes arcs during fault conditions and ensures high breaking capacity up to 100kA, making it suitable for heavy industrial applications.
