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 100 A to 800 A (IEC) and from 100 A to 400 A (UL) at voltages up to 1500 V DC. Due to different mounting options, the switches enable a high level of flexibility and efficiency in planning. The series has UL and IEC approvals. The UL variant is only available as a side-operated version. 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. The DC switch disconnectors can therefore be used in the most demanding applications.
