Why Choose the nVent HOFFMAN MSHS401010 Horizontal Busbar Support?
The nVent HOFFMAN MSHS401010 is a robust horizontal main busbar support designed for industrial power distribution assemblies. It supports two 10 × 10 mm busbars per phase and is designed for horizontal installation behind fixed, modular or plug-in systems within compatible nVent HOFFMAN enclosures.
The MSHS401010 mounts to compatible MSPS internal side panels and can be positioned at the required height within the enclosure. This flexibility allows the main busbars to be located according to the assembly design, including installation around the middle of the enclosure height where appropriate to help optimise the required busbar section.
Measuring 300 mm high × 95 mm wide, the MSHS401010 is manufactured from polycarbonate reinforced with 10% glass material. It provides a 20 mm distance between busbars, supports three phases and neutral, and has been tested according to IEC 61439. This 2 × 10 × 10 mm configuration is commonly specified for horizontal busbar systems rated up to 750 A.

Flexible Support for Horizontal Main Busbar Systems
The nVent HOFFMAN MSHS range provides a flexible way to support horizontal main busbars behind electrical compartments. By mounting the MSHS401010 to MSPS internal side panels, panel builders can position the busbar assembly at the height required by the electrical design rather than being restricted to a single fixed mounting location.
The MSHS401010 is configured for two 10 × 10 mm bars per phase and provides defined 20 mm spacing between the bars. Its reinforced polycarbonate construction provides electrical insulation and mechanical support, while IEC 61439 testing supports its use in professionally engineered low-voltage switchgear and controlgear assemblies.
Typical Applications
- 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 electrical enclosures fitted with MSPS internal side panels.
