Why Choose the Mersen W1027153 MULTIVERT® Fuse Switch Disconnector?

The Mersen W1027153 is a robust NH vertical fuse switch disconnector designed for safe switching, isolation and circuit protection in demanding low-voltage power distribution systems. Part of the proven Mersen MULTIVERT® 630 A series, it is engineered for direct installation onto 185 mm busbar systems in industrial switchboards and distribution cabinets.

This three-pole unit uses a 3 × 1-pole switching configuration, allowing each phase to be operated independently. Its modular design supports fast installation and straightforward maintenance while providing a high degree of protection for engineers working on industrial and commercial distribution equipment.

Rated at 630 A and 690 V AC, the W1027153 accepts NH Size 3 fuse-links manufactured in accordance with IEC/EN 60269-2 and VDE 0636-2. The unit features M12 screw connections, is prepared for fuse monitoring facilities and provides an SCCR of up to 80 kA, depending on the operating voltage and current.

Key Advantages

  • Heavy-duty NH fuse switch disconnector for industrial power distribution.
  • 630 A rated current for high-load electrical circuits.
  • 690 V AC rated operational voltage.
  • Designed for NH Size 3 fuse-links.
  • Direct installation onto 185 mm busbar systems.
  • 3 × 1-pole switching supports independent phase operation.
  • High short-circuit rating for dependable electrical protection.
  • Modular design simplifies installation and maintenance.

Key Features

  • Mersen MULTIVERT® 630 A series.
  • 630 A conventional free-air thermal current with fuse-links.
  • 690 V AC IEC rated voltage.
  • Three-pole construction.
  • 3 × 1-pole switching configuration.
  • M12 screw connections.
  • Designed for 185 mm busbar mounting.
  • Prepared for indication and fuse-monitoring facilities.
  • 12 kV rated impulse withstand voltage.
  • 1,000 V rated insulation voltage.
  • RoHS-compliant construction.

Reliable Switching and Protection for Power Distribution

NH fuse switch disconnectors combine circuit isolation and switching with the overcurrent protection provided by compatible NH fuse-links. The Mersen W1027153 enables electrical circuits to be safely disconnected while helping protect cables, equipment and distribution infrastructure against overloads and short circuits.

The MULTIVERT® modular system is designed to simplify the construction of high-current distribution assemblies. Direct mounting onto a 185 mm busbar system reduces installation complexity, while its compact design helps panel builders use available cabinet space efficiently.

Typical Applications

  • Industrial switchboards.
  • Low-voltage power distribution systems.
  • Cable distribution cabinets.
  • Residential and commercial distribution units.
  • Motor control centres.
  • Manufacturing and process facilities.
  • OEM electrical panels and machinery.
