(m7）i-wholesale 3p 4p m7 uchungechunge lwe-mold case circuit Breaker 800a mccb

Isingeniso Somkhiqizo

♦ Uchungechunge lwe-M7 olubunjiwe lwe-circuit breaker lusetshenziselwa i-AC
♦50/60 Hz, i-voltage elinganiselwe engu-690V, ikalwe okwamanje ibe yisekethe yenethi yokusabalalisa amandla angu-800A, esetshenziselwa ukusabalalisa amandla kanye nokuvikela isekethe kanye nezisetshenziswa zamandla ekulayishweni ngokweqile, isekethe emfishane, ngaphansi kwe-voltage njll. Futhi ingasetshenziswa njengesivikelo se-motor infrequent and overload, isifunda esifushane, ngaphansi kwe-voltage. Umkhiqizo unomthamo omncane, ukuphuka okuphezulu, i-arcing emfushane, ingafakwa ekufakweni okuqondile nokuvundlile.
♦ Izinga lokushisa lemvelo: Lingaphansi kuka-50℃
♦ Ukuphakama: Ngaphansi kuka-2000m; Izici zokubekezelela: ukumelana nomswakama, ukumelana nesikhunta, ukumelana nemisebe Izimo zokufaka: cwilisa ngaphansi kuka-22.5
♦ Ukusebenzisa indawo ezungezile: kungasebenza ngokuthembekile ekudlidlizeni okuvamile komkhumbi, ukuzamazama komhlaba(4g). Akufanele kube khona ukugqwala kwezinsimbi, futhi kulimaze igesi efakwa ngaphakathi, ngaphandle kwemvelo eyingozi yokuqhuma kothuli.
♦Okuvamile: GB14048.2

Uhlaka nokufaka ubukhulu

Hlela

♦Ngokwesilinganiso samanje se-125, 160, 315.630,800; I-Nole :125 iyifreyimu engama-63 ethuthukisiwe, i-160 ithuthukisiwe uhlaka oluyi-125., I-315 ithuthukisiwe i-trame engama-250, i-630 ithuthukisiwe ye-trame engama-400)
♦Ngokwephuzu lamaphuzu omthamo:S standard H high breaking.
♦ Ngokusho kwezigxobo 2P3P 4P, Ngokusho kwenhloso. Ukusabalalisa, ukuvikelwa kwezimoto; Ikhodi Yomkhiqizo: None-thermal kazibuthe uhlobo E-electronic uhlobo L-leakage circut breaker
