Thermal disconnectors are used in AC applications. In DC applications, however, there is a danger of continuous arcing because there is no zero crossing. DCD technology has been developed to ensure that the disconnector also works safely in direct current applications. It functions like a wedge which safely interrupts the DC current in case of overload.

For you, this means protection against fire damage caused by DC switching arcs.
