Overhead medium voltage networks must deliver reliable supply while controlling operating costs and managing safety risks. Faults on lateral lines are a major cause of outages and field interventions. Fusesaver™ addresses these challenges directly.
As the world’s fastest MV vacuum circuit breaker, Fusesaver clears faults in as little as half a cycle (10 ms), reducing the impact of transient faults and shortening outage durations. In fire risk areas, minimizing arc duration helps reduce the likelihood of fault related ignition. Its compact, lightweight design enables fast installation and commissioning.
The unique device is self-powered from line current and supports multi-phase fault clearing for both transient and permanent faults. Multiple operating modes (fuse saving, reclosing, sectionalizing and switching) allow utilities to deploy a single device consistently across different network applications.
