(I-1965)m7）I-3p 4p m7 series mold case circuit Breaker ethengiswa ngobuningi

Isingeniso Somkhiqizo

♦I-M7 series molded case circuit breaker isetshenziselwa i-AC
♦50/60 Hz, i-voltage elinganisiwe engu-690V, i-current elinganisiwe ku-800A power distribution net circuit, esetshenziselwa ukusabalalisa amandla nokuvikela isekethe kanye nemishini yamandla ekugcwaleni ngokweqile, i-short circuit, i-voltage engaphansi kwe-voltage njll. Ingasetshenziswa futhi njengokuvikela ukuqala nokulayisha ngokweqile kwenjini okungajwayelekile, i-short circuit, i-voltage engaphansi kwe-voltage. Umkhiqizo unevolumu encane, ukuphuka okuphezulu, i-arcing emfushane, ungafakwa ekufakweni okuqondile nokuvundlile.
♦Izinga lokushisa lemvelo: Ngaphansi kuka-50℃
♦Ukuphakama: Ngaphansi kuka-2000m; Izici zokubekezelela: ukumelana nomswakama, ukumelana nesikhunta, ukumelana nemisebe Izimo zokufakwa: cwilisa ngaphansi kuka-22.5
♦ Ukusebenzisa indawo: kungasebenza ngokuthembekile ekudlidlizeni okuvamile komkhumbi, ukuzamazama komhlaba (4g). Akufanele kube nesenzo esibhubhisayo ezinsimbini, futhi kulimaze igesi yokushisa, ngaphandle kokuqhuma kothuli okuqhuba ingozi endaweni yezinto ezibonakalayo.
♦Okujwayelekile: GB14048.2

Uhlaka kanye nobukhulu bokufaka

Hlela ngezigaba

♦Ngokusho kwamanje okulinganiselwe okungu-125,160,315.630,800; I-Nole:125 ingu-63 ozimele othuthukisiwe, i-160 ingu-125 ozimele othuthukisiwe., i-315 ingu-250 ozimele othuthukisiwe, i-630 ingu-400 ozimele othuthukisiwe)
♦Ngokusho kwamaphuzu omthamo wokuphuka: Ukwephuka okuphezulu kwe-S okujwayelekile kwe-H.
♦Ngokusho kwezigxobo 2P3P 4P, Ngokusho kwenhloso. Ukusabalala, ukuvikelwa kwemoto; Ikhodi Yomkhiqizo: Uhlobo lwe-magnetic olungenawo ugesi olushisayo lwe-E-electronic uhlobo lwe-L-leakage circut breaker
