ABB OTC60G3-3BS three-pole 60 A manual change-over switch with I-0-II operation, screw terminals, DIN-rail mounting capability and a padlockable direct handle.
The ABB OTC60G3-3BS, product code 1SCA162741R1001, is a robust three-pole manual change-over switch designed for reliable switching between two electrical power sources. As part of the advanced ABB OT Plus change-over switch range, it provides dependable I-0-II operation for industrial power distribution, machinery and control-panel applications.
This front-operated switch combines a compact, base-mounted design with DIN-rail mounting capability, helping simplify installation inside electrical switchboards and control cabinets. Integrated screw terminals provide secure conductor connections, while the supplied direct-mounted knob handle enables convenient manual operation.
With a rated current of 60 A, a three-pole configuration and support for operating voltages up to 600 V AC under UL ratings, the OTC60G3-3BS is suitable for demanding power-transfer applications. Its padlockable operating handle helps prevent unauthorised switching and supports safer maintenance procedures.
Manual change-over switches allow an electrical load to be transferred between two separate power supplies. The central OFF position isolates the connected circuit before the alternative source is selected, helping reduce the risk of the two supplies being connected simultaneously.
The ABB OTC60G3-3BS is designed for power-distribution engineers, panel builders and industrial equipment manufacturers. Its compact mounting format, secure terminals and lockable operating mechanism make it suitable for installations where dependable source selection and straightforward manual control are required.
