Efficient Isolation for 1500 V DC Power Systems

DC switch disconnectors such as the ABB OTDC200GV11 provide a dependable means of switching and isolating direct-current circuits. High-voltage DC systems place particular demands on switching equipment because a DC arc does not naturally pass through a zero-current point in the same way as an AC waveform, making purpose-designed DC switching technology essential for reliable circuit isolation.

The OTDC S2.0 platform is specifically optimised for 1500 V DC applications. Its two-pole architecture provides high electrical performance in a compact footprint, helping equipment manufacturers reduce enclosure space and switching losses while maintaining the isolation performance required by modern photovoltaic, energy and industrial DC systems.
