Environmental Conditions
Ambient tembiricha: -40°C~+40°C (pasi pe35°C mukati memaawa makumi maviri nemana)
Hunyoro hunoenderana: ≤95% (avhareji yezuva nezuva) kana ≤90% (avhareji yepamwedzi)
Kureba: ≤ 1000m
Muchina wekushandisa imhando yemagetsi yakachengetwa isina rwendo ine yakazvimirira kuvhura uye kuvhara zvisinei nekuita kwemushandisi.Iyo yekushandisa michina inoshandiswa zvakanyanya mune ese VD4-R akateedzana maseketi-mabreaker ane frontal control.
Iyo yedunhu-inopwanya inogona kudzorwa kure kana yakashongedzwa neakazvitsaurira magetsi accessories (gearmotor, kuvhura uye kuvhara kuburitswa).
Mashandisirwo ekushandisa, mapango matatu uye masensa azvino (kana akapihwa) akaiswa pasimbi isina mavhiri.Chivakwa chacho chinonyanya kusimba, chakasimba uye chehuremu hushoma.
VD4-R series circuit-breaker with lateral operating mechanisms are life-long sealed pressure devices.(Mitemo IEC 62271-100)
