Why Choose the nVent HOFFMAN MSHS402010 Horizontal Busbar Support?
The nVent HOFFMAN MSHS402010 is a robust horizontal main busbar support designed for industrial power distribution assemblies. It supports two 20 × 10 mm busbars per phase and is designed for horizontal installation behind fixed, modular or plug-in systems within compatible nVent HOFFMAN enclosures.
The MSHS402010 mounts to compatible MSPS internal side panels and can be positioned at the required height within the enclosure. This flexible arrangement allows the main busbars to be located according to the electrical design, including installation around the middle of the enclosure height where appropriate to help reduce the required busbar section.
Measuring 380 mm high × 95 mm wide, the MSHS402010 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. The 2 × 20 × 10 mm configuration is specified for horizontal busbar systems rated up to 1000 A.

Flexible Support for 1000 A Horizontal Main Busbar Systems
The nVent HOFFMAN MSHS range provides a flexible method for supporting horizontal main busbars behind electrical compartments. By mounting the MSHS402010 to MSPS internal side panels, panel builders can position the busbar assembly at the required enclosure height rather than being restricted to a single fixed mounting location.
The MSHS402010 is configured for two 20 × 10 mm busbars per phase with a defined 20 mm spacing between the bars. Its glass-reinforced polycarbonate construction provides mechanical support and electrical insulation, while its tested short-circuit performance and compliance with IEC 61439 make it suitable for professionally engineered industrial switchgear and power distribution assemblies.
Typical Applications
- Industrial low-voltage power distribution systems.
- Horizontal main busbar systems rated up to 1000 A.
- 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.
