The manually operated switch disconnectors of the OTDC series are a cost-effective and reliable solution for a wide range of industrial DC applications. The OTDC series switches currents from 16 A to 32 A without any problems at voltages up to 1000 V DC. Thanks to various mounting options, the switches enable a high level of flexibility and efficiency in planning. The series has an IEC approval and guarantees reliable breaking performance at all currents without compromising safety. In addition, the switches are designed to be used in particularly high ambient temperatures. In addition, the power loss has been reduced by 50%. ABB offers you a wide range of accessories for these switches, such as extension shafts, handles, auxiliary switches and terminal covers. This means that the DC switch disconnectors can be used in the most demanding applications.
