The Mersen F1023206, catalogue number 1.200.094, is a high-performance MULTIVERT® NH fuse switch disconnector designed for safe switching, circuit isolation and overcurrent protection in industrial low-voltage power distribution systems. This 400 A, Size 2, three-pole unit mounts directly onto a 185 mm busbar system, making it suitable for switchboards, distribution cabinets and motor control centres.
As part of the proven Mersen MULTIVERT® 400 A series, the F1023206 combines a compact vertical design with modular construction for efficient installation and maintenance. Its three independently switched poles provide dependable control of three-phase circuits, while robust M12 bolted terminals support secure cable connections in demanding industrial environments.
The F1023206 incorporates three 400/5 A current transformers for three-phase current measurement. Each transformer is rated at 3.75 VA, Class 1, allowing the device to support load monitoring, metering and energy-management applications while retaining the protection and isolation functions of a conventional NH fuse switch disconnector.
NH fuse switch disconnectors combine manual switching and circuit isolation with the high fault-clearing capability of NH fuse links. This allows maintenance teams to isolate equipment safely while protecting cables, machinery and distribution circuits against overloads and short circuits.
The three integrated current transformers distinguish the Mersen F1023206 from standard fuse switch disconnectors. They provide current signals from all three phases, supporting metering, load analysis and energy-management systems without requiring separate externally mounted transformers.
