IyoHM4 yepakati-voltage circuit breakermashandisirwogasi resarufa hexafluoride (SF6)senzvimbo inodzima nekudzivirira kupisa.
SF6 gasiine hunhu hwekupwanya hwakatsetseka, uye kana magetsi achipwanya, hapana chinhu chinocheka magetsi uye hapana simba remagetsi rinogadzirwa.
Izvihunhu hwakanaka kwazvoinoita kuti circuit breaker igare kwenguva refu.
Uyezve, panguva yekushanda, hazvikanganisi kuvhunduka kwemuchina, mwero we dielectric, uye kushushikana kwekupisa.
Chivharo chedanda checircuit breaker, kureva chikamu chekamuri chinodzima arc, inzira yakavharwa isina kugadziriswa kwehupenyu hwese. Nguva yayo yekuvharira inoenderana neIEC 62271-100 uye CEI17-1.
