Why Choose the Mersen L1023050 MULTIBLOC 000.RST8 Fuse Switch Disconnector?
The Mersen L1023050, catalogue number 1.002.572, is a compact NH fuse switch disconnector designed for switching, isolation and fuse protection in low-voltage electrical distribution systems. Part of the Mersen MULTIBLOC 000.RST8 series, it is a three-pole unit designed for NH size 000 fuse links and installation directly onto a busbar system.
The MULTIBLOC 000.RST8 combines fuse protection and switching functionality in a space-efficient format for industrial switchboards and distribution assemblies. Its busbar-mounted construction makes it particularly suitable for compact distribution systems where outgoing circuits are connected directly to a common busbar arrangement.
The L1023050 has a rated current of 100 A and a rated operational voltage of 690 V AC. It features three frame-clamp terminals accepting conductors from 2.5–50 mm², with the cable connection positioned at the top of the unit for installations requiring a top-terminal configuration.

Reliable Fuse Protection for Busbar Distribution Systems
NH fuse switch disconnectors combine circuit switching and isolation with the protection provided by replaceable NH fuse links. This allows distribution circuits to be isolated while providing overload and short-circuit protection according to the characteristics and rating of the installed fuse links.
The Mersen MULTIBLOC 000.RST8 is specifically configured for busbar-mounted applications. Its compact three-pole construction, NH size 000 compatibility and top cable terminals make the L1023050 suitable for outgoing circuits in industrial and commercial low-voltage distribution assemblies.
Typical Applications
- Industrial low-voltage distribution systems.
- Busbar-mounted electrical distribution assemblies.
- Electrical switchboards and distribution panels.
- Three-phase circuit switching and isolation.
- Industrial machinery power distribution.
- NH size 000 fuse-based protection systems.
