CONTROLLER FOR PASSAGE OF ELECTRIC CURRENT SUPPLIED TO ELECTROTHERMOMAGNETIC DEVICES Russian patent published in 2009 - IPC H01H73/48 

FIELD: physics; electricity.

SUBSTANCE: controller for passage of electric current supplied to electrothermomagnetic devices is designed for current limiting the moment current intensity exceeds a critical point. The device contains two half-bodies which can be interconnected thus forming body, fixed and moving contacts coupled with all complementary components, as well as handle integrated with manual cylindrical wheel functionally connected to the electromagnetic coil activating disconnecting hammer and rod, as well as cylindrical shaft with mounted supporting base, lever with moving contact connected to break device on its one end. The other end contains the bearing on the hammer of electromagnetic coil actuated thus invoking disconnection of moving contact if overcurrent passes through electromagnetic coil.

EFFECT: higher efficiency of wide-range current control.
