The manually operated switch disconnectors of the OT series are unique in their variety and flexibility. The OT series switches currents from 16 A to 4000 A and 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 freely selectable installation position enables a high level of flexibility and efficiency in planning. In addition, the OT switches can be used as main switches in the main or sub-distribution board. Of course, the OT series also has IEC and UL approvals, which make this series even more attractive. ABB also offers you a wide range of accessories for these switches, such as extension shafts, handles, auxiliary switches and terminal covers. This means that the OT switch disconnectors can also be used in the most demanding applications.
