The Mersen H1023208 is a MULTIVERT® NH vertical fuse switch disconnector designed for dependable switching, isolation and fuse protection in industrial low-voltage power distribution systems. Rated at 400 A and up to 690 V AC, it is engineered for direct installation onto standard 185 mm busbar systems.
This three-pole unit accommodates NH Size 2 fuse links and uses a V-terminal cable connection, allowing compatible V-clamps to provide secure conductor termination. Its compact standard-depth design helps conserve space inside distribution cabinets while retaining the modular flexibility associated with the Mersen MULTIVERT® platform.
With utilisation categories including AC-23B at 400 V, a short-circuit current rating of up to 120 kA under specified operating conditions and compliance with recognised IEC standards, the H1023208 is suitable for demanding switchboards, feeder systems and industrial distribution assemblies.
When fitted with an appropriately selected NH Size 2 fuse link, the Mersen H1023208 provides effective protection against overload and short-circuit conditions. Its switching mechanism also allows the connected circuit to be isolated for maintenance, inspection or equipment replacement.
The unit mounts directly onto a 185 mm busbar system, reducing wiring requirements and helping panel builders create compact, modular distribution assemblies. Its V-terminal configuration provides installation flexibility by accepting compatible terminal clamps selected for the conductor size and application.
The standard MULTIVERT® design has an installation depth of approximately 123 mm, making it particularly useful in power distribution cabinets where internal space is limited. Its symmetrical, modular construction also supports straightforward integration with compatible Mersen accessories.
