Low voltage switchboard HMS
Holtab Modular Switchboard
Holtab Modular Switchboard (HMS) is a modular system that offers full freedom when choosing electrical components. This also gives flexibility in terms of width, height and depth so that the switchgear units can be totally adapted to the installation site.
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.
EMF - Low radiation
HMS switchgear units are also available as an EMF version, which are ideally used when there’s a high demand for low magnetic fields. This version generates less than five percent magnetic field compared to standard models on the market.
Increased flexibility
The flexibility inherent in the HMS system means that the switchboard can be designed to suit physical conditions in the existing space or to various requirements regarding the components and devices included.

EMF reducing switchgear
We have developed an EMF reducing switchgear that can be placed in buildings where there’s a particularly high demand for low magnetic fields. We’ve modified our low-radiation switchgear so they generate less than five percent magnetic field in comparison to standard models on the market.
