Describe Display

The NCX/RW series 12 kV drop-out fuse offers reliable overcurrent protection and load isolation in medium-voltage distribution networks. Its clear, visible dropout mechanism allows operators to verify fuse operation at a glance, while the robust housing ensures long-term durability in both indoor and outdoor applications.

Designed for seamless integration, the series supports multiple load ratings and switchgear types, providing rapid fault clearing and safe maintenance access. With optimized arc-quenching performance and a compact profile, these fuses enhance system uptime and protect critical equipment in industrial, utility, and infrastructure installations.
