QSA – Auxiliary service panels

IMESA Low Voltage Switchboards consist of standardized modular units which can be easily coupled, even if they are of different type. IMESA manufactures the following types of LV switchboards:

QSA Auxiliary service panels

The main characteristics of Low Voltage Switchboards are:

Modular design
Structural forms according to the regulations
Internal arc proof version
Very compact solutions
Easy installation and maintenance
Type tests and acceptance tests

Thanks to their characteristics, IMESA Low Voltage Switchboards can offer solutions for any kind of request, always ensuring service continuity, personnel security and the possibility to implement the switchboard in a supervision and control system.

LV Switchboards ensure versatility, they are suitable to be differently installed in main electrical plants such as:

Industrial (cement, petrochemical, metallurgical and paper factories)
Production and distribution of electric power (electric power plants, substations, cogeneration, alternative energy)
Shipbuilding (passenger ships, military ships, merchant ships, platforms)
Infrastructures (railways, undergrounds, airports)
