I-YUANKYI-N7R Series Residual Current Breaker(RCCB) sisixhobo sokukhusela ukuvuza esisebenza kakuhle kakhulu esenzelwe iinkqubo zokusasazwa kwamandla kwiindawo zokuhlala, zorhwebo kunye nemizi-mveliso kwihlabathi liphela. Sihambelana ngokupheleleyo nemigangatho ye-IEC/EN 61008‑1, sisebenza kwi-50/60Hz, sifanelekile kwiisekethe ze-230V zesigaba esinye kunye ne-400V zesigaba sesithathu. Olu luhlu lubonelela nge-currents ezilinganisiweyo ukusuka kwi-16A ukuya kwi-100A kunye nobuntununtunu obushiyekileyo ukusuka kwi-10mA ukuya kwi-500mA, ezifumaneka kwiinguqulelo ze-2‑pole kunye ne-4‑pole ukuhlangabezana neemfuno ezahlukeneyo zokhuseleko.

I-N7R RCCB isebenzisa isakhiwo se-electromagnetic esicocekileyo esinezinto ezimbalwa kwaye akukho mfuneko yokunikezelwa kwamandla okuncedisa, iqinisekisa ukusebenza okuzinzileyo okungachaphazeleki kubushushu obuphakathi okanye ukuphazamiseka kombane. Ulwakhiwo lwayo oluncinci, ukuthembeka okuphezulu kunye nobomi benkonzo ende kwenza ukuba ilungele ukusebenza ixesha elide. Le mveliso ixhasa ukufunyanwa kokuvuza kohlobo A kunye nohlobo lwe-AC, kunye neentlobo zokusebenza ze-electromagnetic kunye ne-elektroniki, inika ukuhambelana okuqinileyo kwiimarike zehlabathi.

Esi sixhobo sisebenzisa i-transformer yangoku ye-zero sequence eyakhelwe ngaphakathi ukuze ibone umahluko we-vector phakathi kwe-phase kunye ne-neutral currents. Phantsi kweemeko eziqhelekileyo, i-currents engenayo nephumayo iyalingana, kwaye i-breaker ihlala ivaliwe. Xa kusenzeka ukuvuza, ukutshayiswa kombane okanye ukungasebenzi kakuhle kwe-insulation, ukungalingani kwamanje kuvelisa isignali ebangela ukuba indlela yokukhubeka ikhubeke. I-breaker ikhawuleza iqhawule i-circuit ukuze kuthintelwe ukutshayiswa kombane, umlilo wombane kunye nomonakalo wezixhobo, ibonelela ngokhuseleko lomntu kunye nolwesekethe olukhawulezayo nolusebenzayo.

Yenzelwe ukuba kube lula ukuyifakela, uthotho lwe-N7R luxhasa ukufakwa kwe-35mm DIN‑rail kunye neentambo eziphezulu/ezantsi. Ikhusela i-IP20, ubushushu bokusebenza obuphakathi kwe-−25℃ ukuya kwi-+40℃, ubomi bombane obuphindwe ka-6000 kunye nobomi boomatshini obuphindwe ka-10000. Isetyenziswa kakhulu kwiifektri, kwizakhiwo zorhwebo, kwiindawo zokuthenga ezinkulu, kwiindawo zokuhlala, kwiikhabhathi zokusasaza umbane kunye neenkqubo zombane zasekhaya.

Ngomthamo ophezulu wokuqhekeka, ukusebenza okuzinzileyo kunye nolawulo oluqinileyo lomgangatho, iYUANKY N7R Series RCCB ibonelela ngokhuseleko olukhuselekileyo, oluthembekileyo nolungabizi kakhulu kubathengi kwihlabathi liphela. Lukhetho olukhethwayo kubafaki abaziingcali, abakhi kunye nabadibanisi beenkqubo.
