The motor-operated switch disconnectors of the OSM series from ABB are ideal for installations that require remote operation. The OSM series switches currents from 32 A to 1250 A at voltages up to 690 V AC. The maintenance-free motor is available in operating voltages from 220 V to 240 V AC / DC, depending on the type. To ensure a high level of safety, the motors are protected against overcurrent with a fuse. All OSM switches have an integrated fuse chamber in which fuses of different designs can be inserted. The series also has IEC approval. ABB offers you a large selection of accessories for these switches, such as extension shafts, handles, auxiliary switches and terminal covers. The simple handling makes the series an optimal solution for a wide variety of applications.
