The Mersen R1023262 is a high-performance NH vertical fuse switch disconnector designed for switching, isolation and circuit protection in industrial low-voltage power distribution systems. Part of the established Mersen MULTIVERT® 630 A series, it provides a compact and dependable solution for panel builders, electrical engineers and OEM manufacturers.
This fuse switch disconnector is designed for direct installation onto 185 mm busbar systems in a three-pole arrangement. Its modular construction supports fast assembly and straightforward servicing while providing a high degree of protection during installation and maintenance.
With a rated current of 630 A, a rated voltage of 690 V AC and compatibility with NH Size 3 fuse-links, the R1023262 is suitable for demanding industrial distribution circuits. The unit features simultaneous 1 × 3-pole switching and lateral M12 screw connections for secure cable termination.
The Mersen R1023262 combines load switching, electrical isolation and fuse protection within one compact assembly. When fitted with correctly rated NH Size 3 fuse-links, it helps protect industrial distribution circuits against overloads and short circuits while providing a clear means of isolating equipment for maintenance.
Its direct busbar mounting arrangement reduces installation complexity and helps create an organised, space-efficient switchboard layout. The compact standard design has an installation depth of approximately 123 mm, making it particularly suitable for power distribution cabinets where available space is limited.
