Abstract

The invention relates to a trip device for electrical switching apparatuses by means of an explosive charge (17) which can be detonated and causes the switching apparatus to trip, the explosive charge being formed by a pyrotechnic gas generator which acts on a pressure piston unit (16) which is coupled to the moving contact part (7) of the switching apparatus. <IMAGE>
