The manually operated load break switches of the OT series are unique in their variety and flexibility. The OT series can switch currents from 16 A to 4000 A at voltages of up to 1000 V AC. Despite their high performance, the switches are very easy to operate and take up little space. The ability to choose the installation position freely allows for high flexibility and efficiency in planning. Furthermore, the OT switches can be used as main switches in main or sub-distributions. Of course, the OT series also has IEC and UL approvals, making this series even more attractive. Additionally, ABB offers a wide range of accessories for these switches, such as extension shafts, handles, auxiliary switches, and terminal covers. Thus, the OT load break switches can also be used in the most demanding applications.
