The motor-operated switch disconnectors of the OTM series are unique in their variety and flexibility. The OTM series switches currents from 40 A to 2500 A at voltages of up to 1000 V AC. The maintenance-free motor is available in operating voltages from 110 V to 240 V AC and 24 V DC, depending on the type. To ensure a high level of safety, the motors are protected against overcurrent with a fuse. Thanks to its compact design and simple wiring, the OTM series is suitable for numerous installations that require remote operation. In addition, the switch can be operated manually at any time. The OTM series also has IEC approval. ABB offers you a wide range of accessories for these switches, such as extension shafts, handles, auxiliary switches and terminal covers. The simple handling makes the OTM series an optimal solution for a wide variety of applications.
