The manually operated load disconnect switches of the OT series are unique in their variety and flexibility. The OT series switches currents from 16 A to 4000 A at voltages of up to 690 V AC. Despite their high performance, the switches are very easy to operate and take up little space. The selectable installation position allows for high flexibility and efficiency in planning. The OT load disconnect switches can be used as main switches in main or sub-distributions. ABB also offers a wide range of accessories for this series, such as extension shafts, handles, and terminal covers. This makes OT load disconnect switches suitable for even the most demanding applications.
