Mersen: ProGrid Solutions – New generation of modular NH fuse switch disconnector (GSA27-58)
ProGrid Solutions was designed to protect, monitor, detect and report events on the low-voltage grid.
At the core of ProGrid is a patented dual side switching mechanism that releases NH fuse blades in parallel, ensuring optimal arc interruption while maintaining IP20 contact protection, then opens in rotation for easy fuse replacement.
This innovation maximizes operator safety and optimizes clearance distances, making ProGrid one of the safest NH Fuse switch disconnectors solution available.
The system is modular and future proof, ranging from standard NH FSD units to fully intelligent configurations. Smart versions integrate embedded sensors that measure energy flows, and can be extended up to monitoring transformer health, environmental conditions and cabinet access, enabling predictive maintenance and supporting the digitalization of LV infrastructure.
ProGrid can be upgraded from Standard to Smart without modifying the footprint and panel configuration, simplifying deployment and retrofitting. Its compact design, simple installation and real time monitoring capabilities support efficient energy management, industrial resilience and modern smart grid architectures.
