Ubushinwa VD4 bukurikirana vacuum circuit-breakers ni ibikoresho byo kwishyiriraho ibikoresho byo mu nzu.Nyamuneka saba ROCKWILL kubisabwa bidasanzwe byo kwishyiriraho.VD4-R ikurikirana ya voltage iciriritse yamashanyarazi yamashanyarazi hamwe nuburyo bukoreshwa muburyo bwo kwishyiriraho imbere biranga tekinike yo kubaka inkingi.Buri nkingi ibamo icyuho cyahagaritswe muri resin iyo silinderi ibumbwe bitewe nuburyo budasanzwe bwo gukora.Ubu buryo bwubwubatsi burinda icyuho cya vacuum guhungabana, umwanda hamwe na kondegene.
Uburyo bukoreshwa nuburyo bwingufu zabitswe zidafite imbaraga zo gufungura no gufunga utitaye kubikorwa byabakoresha.Uburyo bukoreshwa bukoreshwa cyane muri VD4-R zose zikurikirana zumuzenguruko hamwe no kugenzura imbere.
Inzira-yamashanyarazi irashobora kugenzurwa kure mugihe yashyizwemo ibikoresho byabigenewe byamashanyarazi (gearmotor, gufungura no gufunga gusohora).
Uburyo bukoreshwa, inkingi eshatu hamwe na sensor zubu (niba zitanzwe) zashyizwe kumurongo wicyuma udafite ibiziga.Kubaka biroroshye cyane, birakomeye kandi bifite uburemere buke.
VD4-R ikurikirana yamashanyarazi hamwe nuburyo bukoreshwa muburyo bukurikira ni ibikoresho byumuvuduko wubuzima. (Ibipimo IEC 62271-100)
