Why Choose the nVent HOFFMAN MSHS412010 Horizontal Busbar Support?
The nVent HOFFMAN MSHS412010 is a heavy-duty horizontal main busbar support designed for high-current industrial power distribution assemblies. It supports two busbars up to 120 × 10 mm per phase and forms part of the nVent HOFFMAN MSHS range, which supports horizontal main busbar systems rated up to 3600 A.
The MSHS412010 is designed for installation behind fixed, modular and plug-in systems and mounts to compatible MSPS internal side panels. It can be positioned at the required height within the enclosure, providing panel builders with flexibility when arranging the main power distribution system. Installing main busbars around the middle of the enclosure height can also help reduce the required busbar section in suitable system designs.
Measuring 780 mm high × 95 mm wide, the MSHS412010 supports two 120 × 10 mm bars per phase with a 20 mm distance between bars. It is manufactured from polycarbonate reinforced with 10% glass material, supports three phases and neutral, and has been tested according to IEC 61439 for integration into professionally engineered low-voltage power distribution assemblies.

High-Current Support for Horizontal Main Busbar Systems
The nVent HOFFMAN MSHS412010 provides the mechanical support and electrical insulation required for large horizontal main busbars within industrial power distribution assemblies. Designed to accommodate two bars up to 120 × 10 mm per phase, it is suited to demanding applications where substantial busbar cross-sections are required for high-current distribution.
Mounting to MSPS internal side panels allows the support to be positioned at the required enclosure height behind fixed, modular or plug-in equipment. Its reinforced polycarbonate construction, defined 20 mm busbar spacing and IEC 61439-tested short-circuit performance provide a reliable foundation for professionally engineered high-current switchgear and controlgear assemblies.
Typical Applications
- High-current industrial low-voltage power distribution systems.
- Horizontal main busbar installations.
- Fixed power distribution assemblies.
- Modular switchgear and controlgear systems.
- Plug-in power distribution systems.
- Industrial floor-standing enclosures fitted with MSPS internal side panels.
