I-YUANKYI-N7R Series Residual Current Breaker(RCCB) iyidivayisi yokuvikela ukuvuza esanda kwethulwa esebenza kahle kakhulu eyenzelwe izinhlelo zokusatshalaliswa kwamandla zokuhlala, ezentengiselwano kanye nezezimboni zomhlaba wonke. Ihambisana ngokugcwele nezindinganiso ze-IEC/EN 61008‑1, isebenza ku-50/60Hz, ifanelekela izifunda ze-single-phase 230V kanye nezigaba ezintathu ze-400V. Lolu chungechunge luhlinzeka ngamaza alinganisiwe kusukela ku-16A kuya ku-100A kanye nokuzwela okusele kusukela ku-10mA kuya ku-500mA, etholakala ngezinguqulo ze-2-pole kanye ne-4-pole ukuze kuhlangatshezwane nezidingo ezahlukene zokuvikela.

I-N7R RCCB isebenzisa isakhiwo esihlanzekile se-electromagnetic esinezingxenye ezimbalwa futhi asikho isidingo sokunikezwa kwamandla okusiza, okuqinisekisa ukusebenza okuzinzile okungathinteki ekushiseni okuzungezile noma ukuphazamiseka kombani. Isakhiwo sayo esincane, ukuthembeka okuphezulu kanye nokuphila isikhathi eside kwenza kube kuhle kakhulu ekusebenzeni kwesikhathi eside. Umkhiqizo usekela ukutholwa kokuvuza kohlobo A nohlobo lwe-AC, kanye nezinhlobo zokusebenza ze-electromagnetic neze-elekthronikhi, okuletha ukuhambisana okuqinile kwezimakethe zomhlaba wonke.

Idivayisi isebenzisa i-transformer yamanje ye-zero sequence eyakhelwe ngaphakathi ukuthola umehluko we-vector phakathi kwe-phase kanye ne-neutral currents. Ngaphansi kwezimo ezijwayelekile, i-current engenayo nephumayo iyalingana, futhi i-breaker ihlala ivaliwe. Lapho kuvela ukuvuza, ukushaqeka kukagesi noma ukwehluleka kokufakwa kwe-insulation, ukungalingani kwamanje kudala isignali ebangela indlela yokukhubeka. I-breaker inqamula ngokushesha i-circuit ukuvimbela ukushaqeka kukagesi, umlilo kagesi kanye nomonakalo wemishini, ihlinzeka ngokuvikelwa komuntu siqu kanye ne-circuit okusheshayo nokuphumelelayo.

Yakhelwe ukufakwa kalula, uchungechunge lwe-N7R lusekela ukufakwa kwesitimela esingu-35mm DIN kanye nezintambo eziphezulu/ezansi. Inesivikelo se-IP20, izinga lokushisa lokusebenza elisukela ku-−25℃ kuya ku-+40℃, impilo kagesi ephindwe ka-6000 kanye nempilo yomshini ephindwe ka-10000. Isetshenziswa kabanzi ezimbonini, ezakhiweni zezentengiselwano, ezitolo ezinkulu, emiphakathini yokuhlala, emakhabetheni okusabalalisa ugesi kanye nasezinhlelweni zikagesi zasekhaya.

Ngomthamo ophezulu wokuphuka, ukusebenza okuzinzile kanye nokulawula ikhwalithi okuqinile, i-YUANKY N7R Series RCCB inikeza ukuvikelwa kokuvuza okuphephile, okuthembekile futhi okungabizi kakhulu kumakhasimende emhlabeni jikelele. Kuyindlela ekhethwayo yabafaki abangochwepheshe, osonkontileka kanye nabahlanganisi bezinhlelo.
