Njengomkhiqizi kagesi ochwepheshe osebenzisa amandla aphansi kagesi onolwazi lweminyaka engama-20 embonini, i-YUANKY iveza uchungechunge lwe-DC S7I-Solar DC Miniature Circuit Breaker(MCB), ikhambi lokusebenza okuphezulu elenzelwe ukuvikelwa kwesekethe ye-DC kanye nokuhlukaniswa, elenzelwe ukufakwa kwelanga le-photovoltaic (PV). Itholakala ngokulungiselelwa kwe-1P kuya ku-4P, isekela ama-voltage alinganisiwe kusukela ku-DC250V kuya ku-1000V, ugesi olinganisiwe kusukela ku-6A kuya ku-50A, kanye nezici ze-C-type tripping (7In-15In). Inikeza umthamo wokuphuka olinganisiwe we-6kA kanye nomthamo wokuphuka olinganiselwe we-15kA wesekethe esifushane ku-250VDC, ngesikhathi sokuphendula esisheshayo kakhulu ≤4ms. Umklamo wayo omusha ongena-polarized uyisimangaliso esiyinhloko, ususa umehluko we-polarity ngesikhathi sokuxhuma izintambo, usindisa kakhulu isikhathi sokufaka futhi ugwema amaphutha okuxhuma izintambo.

Le DC MCB isebenza ngendlela yokuvikela okubili ukuze ixazulule amaphutha avamile ohlelweni lwe-DC. Ukuze kuvikelwe ngokweqile, i-bimetallic strip eyakhelwe ngaphakathi igoba ngokushisa ukuze ibangele indlela yokukhubeka, inqume isekethe kahle ngaphansi kokucindezeleka okuqhubekayo ukuze kuvinjelwe umonakalo wokushisa kwemishini. Uma kwenzeka amaphutha e-short-circuit, ukukhululwa kwe-electromagnetic okuzwela kakhulu kusebenza ngokushesha, kuphazamise ugesi wephutha ngaphakathi kwe-≤4ms ukuze kugwenywe izingozi ezivela kuma-DC arcs. Ifakwe uhlelo lobuchwepheshe lokucima i-DC arc, ixazulula inselele yokuphela kwe-arc kumasekethe e-DC angenalo iphuzu lemvelo lokuwela u-zero, iqinisekisa ukuphuka okuphephile nokuthembekile. Idizayini yokufaka isitimela se-DIN ivumela ukufakwa okulula, okusheshayo kumakhabethe okusabalalisa ajwayelekile.

Ihambisana ngokuphelele nezindinganiso zomhlaba wonke ze-IEC 60947-1/2, umkhiqizo unesitifiketi se-CE kanye nemibiko yokuhlolwa kwe-CB ekhishwe yi-SEMKO, ihlangabezana nezidingo zokufinyelela emakethe yomhlaba wonke. Isebenza kahle ku--5℃ kuya ku-+60℃, ivumelana nezimo zokusebenza ezinzima ezahlukahlukene. Isetshenziswa kabanzi ezinhlelweni ze-PV eziboshwe ngegridi/ngaphandle kwegridi, ezinhlelweni zokugcina amandla ebhethri, amaphaneli okusabalalisa e-DC, iziteshi zezingcingo, imishini yamandla emisha kanye nezifunda zokulawula ze-DC zezimboni, iyisinqumo esihle kakhulu sabafaki be-PV, abahlanganisi bezinhlelo kanye nabakhi bezokwakha kagesi emhlabeni jikelele. Isekelwa ukulawulwa kwekhwalithi okuqinile kanye nensizakalo ephelele yokuthengisa ngaphambi kokuthengisa nangemva kokuthengisa, i-YUANKY DC MCB inikeza ukuvikelwa okuthembekile nokuhlala isikhathi eside kwezinhlelo zikagesi ze-DC emhlabeni jikelele.
