Low voltage switchboard CMS

Flexible modular construction

Our modular-designed and modern low-voltage switchgear offer full freedom when choosing electrical components and we will be only too happy to provide a proposal for the most cost-effective solution. This also gives flexibility in terms of width, height and depth so that the switchgear units can be totally adapted to the installation site.

Product quality

As an accredited switchgear contractor, we have undergone extensive and thorough training. This means we can guarantee a high and consistent level of quality across all our products, which are tested and quality inspected before delivery. We set ourselves high standards to exceed expectations and continually assess our quality processes. Our CMS switchgear units are based on one of the market’s best and most efficient platforms, CUBIC.

Operational and personal safety

Our high-quality, low-voltage switchgear units are tested in compliance with IEC/EN 60439-1 and can also be verified in compliance with IEC/EN 61439-2. We also offer complete personal and operational safety tests according to our customer’s requirements.

Modern switchgear with a modular design

Modern switchgear with a modular design

Our modular-designed and well-documented low-voltage CMS switchgear units are based on CUBIC’s switchgear system and are available in different solutions for any need. Some examples:

  • Main and distribution switchboards
  • Service switchgear
  • Motor Control Centres (MCC)
  • Ship switchgear
  • Cassette switchgear (Multi Drawer)
  • Distribution centres

The switchboard system is available for most switchgear on the market.

Metering and communications

Metering and communications

Today, many customers demand sophisticated solutions in addition to pure electrical distribution. There is increasing demand for functions such as metering of outgoing groups, grid analysis, earth fault monitoring, alarm management, arc fault monitors and remote control via control system nodes or bus solutions.

Today’s modern circuit breakers, multi-metering and relay protection also improve the ability to achieve a complete overview of an electrical installation cheaply and simply from any location via web-based functions.

Separation

Separation

Holtab CMS provides optional separation from FORM 1 to 4 and thus optimal operational safety and reliability in full compliance with IEC/EN 61439 and customer requirements. It’s possible to carry out visual and thermographic inspections of busbar joints after switchboard installation and commissioning.

Tests and certifications

Tests and certifications

Because CUBIC places great emphasis on operation reliability and safety it regularly carries out the additional tests that the market demands such as earthquake, shock and arc fault tests. CUBIC’s products are tested and/or type approved by the world’s most prominent certification institutes.
