Mersen NH12CERAMWALLE, catalogue number Q215202, is a fixed ceramic partition wall for compatible NH size 1 and size 2 fuse bases used in 400 A low-voltage fusegear assemblies.
Why Choose the Mersen NH12CERAMWALLE Ceramic Partition Wall?
The Mersen NH12CERAMWALLE is a specialist ceramic partition wall for NH fuse bases, designed to provide durable phase separation within low-voltage fusegear assemblies. Identified by the Mersen catalogue number Q215202, it is intended for use with compatible NH size 1 and size 2 fuse bases.
Installed between adjacent fuse-base poles, the partition wall creates a robust insulating barrier that helps separate live conductive components. Its ceramic construction provides excellent electrical insulation and resistance to the elevated temperatures that may occur within industrial switchboards and power distribution equipment.
The NH12CERAMWALLE is designed for compatible 400 A NH fuse-base arrangements and features a fixed, extended wall format. It is suitable for panel builders, OEMs and maintenance engineers who require the correct manufacturer-specified separator for an existing Mersen or Ferraz Shawmut NH fusegear assembly.

Reliable Phase Separation for NH Fusegear
Partition walls are installed between adjacent poles in multi-pole fuse-base arrangements to increase physical separation between conductive components. This supports an organised fusegear layout and helps improve insulation between phases within the electrical assembly.
The ceramic construction of the Mersen NH12CERAMWALLE makes it particularly suitable for fusegear environments where electrical insulation, dimensional stability and resistance to heat are important. Compatibility should be checked against the fuse-base reference and panel configuration before installation.
Typical Applications
Industrial low-voltage switchboards.
NH fuse-base assemblies.
Power distribution panels.
Motor control centres.
Commercial electrical distribution equipment.
OEM machinery and control systems.
Fusegear maintenance and refurbishment projects.
