Fuse in Switch Solutions

Our fuse in switch units feature a high breaking capacity that safely interrupts fault currents up to 100kA. This capability exceeds many international requirements, providing secure operation in industries with high short-circuit currents, such as heavy machinery or transformer stations. The state-of-the-art arc extinguishing system ensures rapid arc extinction even under DC conditions, which is critical for photovoltaic systems where arcs are notoriously difficult to manage. With our fuse in switch, you can reduce potential arc flash hazards significantly. In independent laboratory tests, units were subjected to more than 3,000 operating cycles under electrical stress, maintaining structural integrity and performance. This high breaking capacity not only ensures safety but also contributes to continuity of service in critical processes.

The optimized footprint of the fuse in switch units saves up to 30% panel space compared to separate fuse and switch arrangements. This compactness enables tighter enclosures and simplifies installation in confined areas, such as telecommunication cabinets, wind turbine nacelles, and EV charging stations. With the growing demand for distributed energy resources, space is a premium. Our compact fuse switch disconnectors allow easy integration without complex modifications. In a retrofit project in a data center, the upgrade to our switch fuse units allowed engineers to fit additional surge protection devices in the same enclosure, increasing system resilience. The reduced dimensions also mean lower material costs for enclosures and simplified wiring, cutting installation time by 25%.
