（m7）Isitolo esidayisa yonke impahla 3p 4p m7 uchungechunge isikhunta icala wesifunda Breaker 800a mccb

Isingeniso Somkhiqizo

♦ I-M7 chungechunge elibunjiwe lekesi lesifunda lisetshenziselwa i-AC
♦ 50/60 Hz, ilinganiselwe i-voltage 690V, ikalwe njengamanje kumjikelezo wenetha lokusabalalisa ugesi ongu-800A, osetshenziselwa ukusabalalisa amandla nokuvikela imishini yamasekethe namandla ku-overload, short circuit, under voltage etc. Futhi kungasetshenziswa njengokuvikelwa kokuqala okungavamile nokulayishwa ngokweqile, isifunda esifushane, ngaphansi kwamandla kagesi. Umkhiqizo unevolumu encane, ukuphuka okuphezulu, i-arcing emfushane, ingafakwa ekufakweni okuqondile nokuqondile.
Temperature lokushisa Environment: Ngaphansi kuka 50 ℃
Itude Ubude: Ngaphansi kuka-2000m; Izici zokubekezelelana: ukumelana nomswakama, ukumelana nesikhunta, ukumelana nemibandela yokufakwa kwemisebe: cwilisa ngaphansi kuka-22.5
♦ Ukusebenzisa imvelo: kungasebenza ngokuthembekile kunyakazisa okujwayelekile komkhumbi, ukuzamazama komhlaba (4g). Akufanele kube nesenzo esonakalisayo kuzinsimbi, futhi kulimaze igesi yokufaka umoya, ngaphandle kwendawo ebonakalayo yokuqhuma kothuli.
Okujwayelekile: GB14048.2

Uhlaka bese ufaka ubukhulu

Hlela

♦ Ngokwesilinganiso samanje esingu-125、160、315.630,800; I-Nole: i-125 ingu-63 ifreyimu ithuthukisiwe, i-160 ingu-125 ifreyimu ithuthukisiwe., I-315 ingama-trame angama-250 athuthukisiwe, i-630 ingama-trame angama-400 athuthukisiwe)
♦ Ngokuya ngamaphoyinti wokuqhekeka kwamandla: Ukweqa okujwayelekile kweS H okuphezulu.
♦ Ngokusho kwezigxobo 2P3P 4P, Ngokusho kwenhloso. Distrioution, motor protesction; Ikhodi Yomkhiqizo: Ayikho-ezishisayo uhlobo kazibuthe E-elektroniki uhlobo L-ukuvuza circut full
