ABB OT63F3 load-break switch 3-pole 63A with black T-handle
The manually operated load break switches 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 load break switches can also be used in the most demanding applications.
Handle and shaft not included. The so-called 'black toggle handle' is almost impossible to switch by hand, but requires an additional selector handle or pistol grip.
