II-HM4 medium-voltage circuit breakerukusebenzisaigesi yesalfure hexafluoride (SF6)njengesixhobo sokucima i-arc kunye nesokukhusela.
Igesi ye-SF6ineempawu zokuphuka ezigudileyo, kwaye xa iphula umsinga kuwo, akukho nto ibangela ukunqunyulwa komsinga kwaye akukho mbane ogqithisileyo oveliswayo.
Okuuphawu oluhle kakhuluiqinisekisa ukuba i-circuit breaker inobomi obude bombane.
Ngaphezu koko, ngexesha lokusebenza, ayinampembelelo kwi-shock yesixhobo, inqanaba le-dielectric, kunye noxinzelelo lobushushu.
Ikholamu yepali ye-circuit breaker, oko kukuthi, inxalenye yegumbi elicima i-arc, yinkqubo evaliweyo engenakugcinwa ixesha elide. Ubomi bayo bokuvala buhambelana nemigangatho ye-IEC 62271-100 kunye ne-CEI17-1.
