Why Choose the Mersen F1023206 MULTIVERT® NH Fuse Switch Disconnector?

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.

Key Advantages

  • Industrial NH fuse switch disconnector for protection, switching and isolation.
  • 400 A rated current for high-power distribution applications.
  • Suitable for operation at up to 690 V AC.
  • Designed for direct installation on 185 mm busbar systems.
  • Three integrated 400/5 A current transformers support three-phase measurement.
  • Robust M12 bolted terminals provide dependable conductor connections.

Key Features

  • Mersen MULTIVERT® 400 A series.
  • NH Size 2 fuse-link compatibility.
  • 400 A conventional free-air thermal current with fuse links.
  • Three independently switched poles.
  • Three 400/5 A, 3.75 VA, Class 1 current transformers.
  • Direct mounting on a 185 mm busbar system.
  • M12 screw and bolt cable connections.
  • Modular vertical design for industrial distribution cabinets.

Reliable Protection with Three-Phase Current Monitoring

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.

Typical Applications

  • Industrial low-voltage switchboards.
  • Power distribution cabinets.
  • Motor control centres.
  • Energy monitoring and metering systems.
  • Manufacturing and process facilities.
  • OEM electrical distribution equipment.
