Abstract (en)
[origin: US4605918A] A high speed current maximum tripping device, comprising a fixed core and a mobile core with complementary shapes and disposed in the same plane while defining an air gap therebetween. The fixed and mobile cores are obtained by flat stamping and have complementary profiles of a generally curvilinear shape with sides whose slope with respect to the main axis of the projecting core increases progressively from the nose towards the body.
