We will use this workshop to demonstrate how relays and contactors are used. The properties of each application also involve corresponding requirements on the switching components. Knowing all about the application is essential for optimal dimensioning.
Many vital items of equipment are driven with standard asynchronous motors. These are reliable and long-lasting, frequently removing the need for costly control systems using frequency converters and the like. With rather larger drives, the star delta starter or a simple softstarter (e.g. from ComatReleco’s CTC, CCC, CCM product family) is usually sufficient both to master the inrush peak in order to meet the technical requirements of energy suppliers, and also to avoid mechanical stresses such as those on joints, V-belts, etc.
