The manually operated load isolators of the OS series from ABB provide optimal protection for the most demanding applications. The OS series switches currents from 20 A to 1250 A at voltages up to 690 V AC. All OS switches feature an integrated fuse chamber that can accommodate fuses of various designs. ABB offers different versions for various fuse standards. Thanks to their modular design, the mechanism and poles can be positioned according to installation requirements, allowing for high flexibility and efficiency in planning. Additionally, the series has IEC and UL approvals. ABB provides a wide range of accessories for these switches, such as extension shafts, handles, auxiliary switches, and terminal covers. The OS switches are an ideal solution for motor protection and can be used in numerous other industrial applications alongside transformers.
