Why Choose the Mersen Q1023215 MULTIVERT® Fuse Switch Disconnector?
The Mersen Q1023215 is a high-performance MULTIVERT® NH vertical fuse switch disconnector designed to combine circuit protection, safe isolation and three-phase current measurement within industrial low-voltage distribution systems. Rated at 400 A and 690 V AC, this three-pole unit is suitable for direct installation onto standard 185 mm busbar systems.
Designed for compatible NH Size 2 fuse-links, the Q1023215 incorporates three factory-fitted 400/5 A, 3.75 VA, Class 1 current transformers. This triple-pole measurement configuration allows the current in all three phases to be monitored without installing separate external transformers, helping to reduce wiring, panel space and installation time.
The unit features robust M12 screw connections and a compact modular design suited to switchboards, transformer substations and industrial distribution cabinets. Its combination of dependable switching, fuse protection and integrated current monitoring makes it an efficient solution for modern power management and energy measurement applications.

Reliable Switching with Three-Phase Current Measurement
NH fuse switch disconnectors combine fuse-based overcurrent protection with a manually operated switching mechanism, enabling circuits to be safely isolated during servicing and maintenance. The Mersen Q1023215 performs these functions while also providing integrated current measurement across all three phases.
Each current transformer converts a primary current of up to 400 A into a proportional 5 A secondary signal for compatible ammeters, protection relays, energy meters or monitoring systems. This integrated configuration can simplify panel design and reduce the number of separately mounted components required within the switchboard.
Typical Applications
- Industrial low-voltage switchboards.
- Transformer substations.
- Motor control centres.
- Energy monitoring and metering systems.
- Commercial power distribution cabinets.
- OEM machinery and electrical control panels.
