LV Switchgears, Controlgears, Automation and Drives
NCE is a solution partner of Siemens.
Together with Siemens, NCE has developed various Low Voltage Switchboards (LVB) and Motor Control Centres (MCC)
based on Siemens LV switchgears and controlgears for different applications for different industries.
NCE provides technical support and switchgear/controlgears spare parts for our customers to ensure smooth and continuous operation and to facilitate testing & commissioning, maintenance, upgrading, modification and even replacement.
Below, you will find some technical information of the major components used in NCE Switchboards and MCC. You can also download product catalogues directly.
Videos of Siemens Products
In response to popular demand of product training, NCE has prepared some videos of basic operations and installation of NCE products. Below you will find some videos of Siemens products. We hope you will find them useful. (If you cannot see the video, you need to download/install the free Adobe Flash Player.)
