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 690 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. The OT switch disconnectors can
be used as main switches in the main or sub-distribution board. ABB also offers a wide range of accessories for this series, such as extension shafts, handles and terminal covers. This means that OT switch disconnectors can also be used in the most demanding applications.
