The RW5-35 drop-out fuse is engineered to provide reliable overcurrent protection for medium and high-voltage overhead lines. Designed for outdoor pole-mounted applications, this fuse effectively isolates faulty line segments by visibly disconnecting upon fuse operation, ensuring fast fault identification and enhanced line safety.
Widely used in rural distribution networks, utility pole circuits, and substation branch feeders, the RW5 fuse is compatible with voltage classes 10kV to 35kV, and complies with IEC 60282-2, GB15166.3, and ANSI C37.42.
