China VD4 mndandanda wa vacuum circuit-breakers ndi zida zopangira ma switchgear m'nyumba.Chonde lemberani ROCKWILL kuti mupeze zofunikira zapadera.VD4-R mndandanda wapakati ma voltage vacuum circuit breakers okhala ndi makina ogwirira ntchito opangira m'nyumba amakhala ndi njira yopangira mizati.Pando iliyonse imakhala ndi chosokoneza cha vacuum chomwe chimakutidwa ndi utomoni pomwe silinda imawumbidwa chifukwa cha njira yapadera yopangira.Njira yomangira iyi imateteza chosokoneza cha vacuum ku mantha, kuipitsidwa ndi kukhazikika.
Makina ogwiritsira ntchito ndi mtundu wamagetsi osungidwa opanda maulendo omwe amatsegula ndi kutseka mosasamala kanthu za zochita za wogwiritsa ntchito.Makina ogwiritsira ntchito amagwiritsidwa ntchito kwambiri pamagulu onse a VD4-R ozungulira omwe amawongolera kutsogolo.
Wowononga dera amatha kuyendetsedwa kutali atayikidwa ndi zida zamagetsi zodzipereka (gearmotor, kutsegula ndi kutseka kumasulidwa).
Makina ogwiritsira ntchito, mizati itatu ndi masensa omwe alipo (ngati aperekedwa) amaikidwa pazitsulo zachitsulo popanda mawilo.Chomangacho chimakhala chophatikizika, cholimba komanso cholemera pang'ono.
VD4-R mndandanda wophwanya ma circuit-breaker okhala ndi ma lateral opareshoni ndi zida zomata kwa moyo wonse. (Miyezo IEC 62271-100)
