FIELD: electricity.
SUBSTANCE: invention is applied in fast-response automatic DC switches for overload and short circuit protection in DC lines and aggregates. Additionally the switch includes spring positioned concentrically inside disconnection spring, so that the springs can affect main anchor directly.
EFFECT: enhanced movement speed of movable contact during disconnection.
