FIELD: electricity.
SUBSTANCE: automatic quick-operating switch includes movable contact, fixed contact, drive rod, contact pressure spring connected to drive rod through stops and bar link, trip-free release electromagnet with armature and trip-free release stop, disconnection spring, main electromagnet with magnetic circuit, main armature and control coil. Rotation axis of movable contact passes through centre of gravity of movable contact, one end of drive rod is connected to movable contact, and the other end is not fixed and its movement is restricted with three stops. Besides on output bus of switch there installed is differential shunt relay which provides interruption of holding current in control coil at current increase in protected circuit to the switch actuation current value.
EFFECT: increasing quick operation and decreasing dimensions of switch.
