This master’s thesis deals with the design of electric switchgear for low voltage, which will serve for presentation purposes. The switchgear is analogy of the modular system MNS 3.0, which includes the latest equipment of ABB Ltd. that is currently available on the market. Switchgears of this type are widely used in industry primarily for controlling motor units. For this reason, in the switchgear there are located motor starters in various performances, as well as distribution modules. In addition, the switchgear has an automatic transfer switch function in case of failure of one of the power supplies. The complete documentation of the switchgear is processed in the professional software EPLAN Electric P8 with use of the 3D software EPLAN Pro Panel for modelling device compartments. The final part of the thesis is the calculation of the maximum cable lengths that a potential customer can connect to the switchgear. In addition, an analysis of the power and control circuits was carried out for voltage drop calculations, as well as the effect of these voltage drops and capacitance of long control cables on the actuation of contactors.
