Why Choose the Mersen Y228756 MULTIVERT Fuse Switch Disconnector?
The Mersen Y228756, catalogue number M01N0G, is a high-performance NH vertical fuse switch disconnector designed for safe switching, isolation and circuit protection in industrial low-voltage distribution systems. As part of the Mersen MULTIVERT® 160 A series, it combines three individually switched poles in a compact assembly for direct installation onto standard 185 mm busbar systems.
Designed for NH00 fuse links, the Y228756 provides dependable on-load switching in accordance with IEC 60947-3 while supporting fuse links manufactured to IEC/EN 60269-2 and VDE 0636-2. Its modular construction helps panel builders create efficient distribution assemblies with straightforward installation, accessible maintenance and a high degree of operational protection.
With a rated current of 160 A, a rated operating voltage of up to 690 V AC and an 80 kA short-circuit current rating at 500 V AC, this fuse switch disconnector is suitable for demanding switchboards, feeder pillars, distribution cabinets and incoming power systems. The integrated M8 screw terminal connection supports secure conductor termination in commercial and industrial installations.

Safe Switching and Circuit Protection
NH fuse switch disconnectors combine fuse-based overcurrent protection with a manual switching and isolation function. This allows electrical circuits to be safely connected, disconnected and isolated while compatible NH fuse links protect cables and equipment against overloads and short circuits.
The Mersen MULTIVERT® system is designed for modular installation on 185 mm busbars. Its symmetrical construction supports flexible top or bottom cable connection, while the individually operated switch covers allow each pole to be controlled separately during installation, servicing and fault isolation.
Typical Applications
- Industrial low-voltage switchboards.
- Commercial and industrial distribution units.
- Cable distribution cabinets.
- Feeder pillars and utility installations.
- Meter distribution systems.
- Building incoming supply units.
- Manufacturing and process-control power systems.
