Abstract

High voltage fusible circuit breaker device having the fusible element or elements embedded in an arc extinguishing powder enclosed in a cartridge or sheath in which the fusible element or each of the fusible elements is made with a reduced cross section over a length or lengths considerable so that the voltage across the continuity solution (s) resulting from melting the reduced length or lengths in cross section is sufficient relative to the electromotive force of the circuit to bring the current to zero and thereby interrupt the circuit .
