With their extremely fast short-circuit interruption they reliably protect transformers, cables, capaci- tors and switching installations against the ther- mal and dynamic effects...

Dummy cartridges > Dummy cartridges are used to test the mechanicalfunction of equipment fitted with h.v.h.b.c. fuses with strikers without current.The dimensions are the same as in the original car-tridges of the h.v.h.b.c. fuses.The test is made by pressing a push-button whichthen ejects the striker pin at an impact force of approx. 70 N and with the same travel as in normal striker cartridges. After each operation the striker pin has to be pressed in again. The dummy cartridges are clearly marked as such and have a s.r.b.p. tube instead of the porcelain tube.
