Реферат: The arc extinction device uses a linearly displaced arc extinction slider (18) of an insulating material, which is inserted between the open switch contacts (12a,14a) and removed from between the closed contacts under control of an energy storage spring (20) and a cooperating release device (16), holding the slider in the inactive position, operated when the short circuit current electromagnetic field reaches a given value, to allow the slider to move between the contacts.
