Abstract
An overcurrent control device for protection of direct-current circuits, employing a saturable reactor to provide for electrical isolation and remote location of the overcurrent detection means from the protected circuit, is provided with additional windings on the reactor and a circuit to render the device fail-safe, while another embodiment provides fail-safe protection using a modified arrangement wherein the additional reactor windings are omitted.
