Moducell Demountable Switchboards

Moducell leads the industry in verification testing. The design is highly flexible, to change layout as your needs evolve. And onsite modifications can happen with minimal power interruption.

  • Type tested arrangement (tested to AS/NZS 61439.1:2016)
  • IP42, IP54, IP66 standard versions
  • Operational voltage ≤1000VAC
  • Fault level withstand ≤100kA
  • Internal arc fault protection ≤ 80kA, 690VAC


Our significant investment into verification testing has taken our rating to 100kA for 1 second on the horizontal and vertical bus systems. 

Fully Withdrawable Switchboards

In-house, we have expertise with assembling and customising fully withdrawable switchboards used in global critical power systems and industries. Our people have intimate knowledge of what is required to meet the highest demands on ‘no-time/down-time’ technology used in industries such as nuclear power, Oil & Gas and water treatment.

With our design and fabrication, you can determine different configurations for front or back connections, top and/or bottom cable entry or double sided.

You also have total OEM freedom of choice. Whatever is optimal for your footprint restrictions and power requirements we will work with.

  • Compliant with AS61439, IEC 60439, IEC 61439-1 & 2
  • Current limit of power incoming and outgoing feeders up to 6300A
  • Rated operational voltage (Ue) 415 / 690V AC
  • Short-circuit withstand capability (150kA)
  • Rated peak current 154kA

Custom Switchboards

To support our ability to manufacture custom-built switchboard enclosures and switchrooms in-house, we have a state-of-the-art manufacturing facility, which is fully equipped with large fixed machinery, including brake presses, guillotine and the latest in turret punch technology, enabling general steel fabrication to high tolerances.

  • Mild steel
  • Stainless steel 304 or 316 grade, painted or unpainted
  • Fully Welded Custom Designed to client specification
  • Customised Sheet-metal Work
  • Ratings up to IP66

PLC/Marshalling Panels

  • Custom Control Panels
  • PLC Panels
  • Enclosed Isolator Panels
  • Marshalling Cubicles
  • Local Control Stations
  • Junction Boxes

Kiosk Substations

Our proven designs, materials and specifications prevent wind driven water ingress, minimise dust entry and ensure sufficient airflow for extreme ambient temperatures – all combining to deliver optimal protection for critical electrical equipment. 

Whether using our kiosk substations for short term emergency response or a long term fix to existing plant, customers can be certain their critical upstream and downstream electrical equipment will be protected and safe.

We provide turnkey solutions incorporating LV and MV switchboards, with all equipment installed in our manufacturing facilities and extensively tested before deployment to site, reducing on-site disruption and costs.

The standard Mayfield Modular Kiosk includes:

  • Detailed design and fabrication
  • MV switchgear
  • Transformer
  • LV switchboards
  • Cabling between MV/Tx/LV
  • Commissioning and testing completed before factory dispatch.

Additional options include:

  • Interconnecting cabling
  • Internal/external power and lighting
  • Transportation of kiosk to site
  • Site installation and commissioning.
