ABB's OS series of manually operated switch disconnectors offer optimum protection for the most demanding applications. The OS series switches currents from 20 A to 1250 A and voltages up to 690 V AC. All OS switches have an integrated fuse chamber in which fuses of different designs can be inserted. ABB offers different versions for different fuse standards. Thanks to the modular design, the mechanism and poles can be positioned according to the installation requirements. This enables a high level of flexibility and efficiency in planning. The series also has IEC and UL approvals. ABB offers you 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 in addition to transformers.
