ABB's series of manually operated load changeover switches is an optimal solution for numerous applications. The load changeover switches switch currents from 16 A to 3200 A and at voltages up to 690 V AC. Despite their high performance, the switches ensure safe operation thanks to a variety of integrated safety functions. The compact design of the series enables optimal use of space. ABB load changeover switches are available in two different versions. These differ in the type of switching: open switching (I-0-II) and closed switching (I-I+II-II). The changeover switches also have IEC and UL approvals. ABB offers you a wide range of accessories for these switches, such as extension shafts, handles, auxiliary switches and terminal covers. In addition, an intelligent control unit can be combined with the switch so that it functions as an ATS (Automatic Transfer Switch). This means that the load changeover switches can be used in the most demanding applications.
