OVERCURRENT PROTECTION DEVICE Russian patent published in 2015 - IPC H01H3/08 H02H3/00 

FIELD: electricity.

SUBSTANCE: device comprises a plate, which one end is fixed in a slot of the plank fixed by bolt to a clamp, which is slipped onto conduct bus mounted on insulators inside the shell of closed current-conducting wire. At the plate surface there are n reed switches fixed in parallel and at the same distance from each other in magnetic field of current passing in the bus of current-conducting wire. To contacts of the reed switches insulated wires are connected by passing through the respective openings in the plate to its opposite surface, whereat these insulated wires are fixed by clamps and through a connector mounted at this surface there are passed by means of cable through opening in the shell of the closed current-conducting wire and coupled to timing unit, which is connected to an operating member. The plate is placed so that its surface with fixed reed switches matches plane of the bus cross-section.

EFFECT: simpler design.
