The HRW5 series drop-out fuse is designed for outdoor high-voltage protection in overhead line networks and distribution transformers up to 12kV. It provides effective overcurrent protection by interrupting short-circuits and overloads with a visible fuse disconnection.
Commonly used in rural grids, substations, and industrial feeders, the HRW5 fuse is a reliable and cost-effective safety solution in medium voltage networks.
