Ib puag ncig tej yam kev mob
ambient kub: -40 ° C ~ + 40 ° C (hauv qab 35 ° C hauv 24 teev)
Cov av noo txheeb ze: ≤95% (qhov nruab nrab txhua hnub) lossis ≤90% (qhov nruab nrab txhua hli)
Qhov siab: ≤ 1000m
Cov txheej txheem kev khiav hauj lwm yog hom kev mus ncig-dawb khaws cia lub zog nrog kev ywj pheej qhib thiab kaw tsis hais tus neeg teb xov tooj qhov kev txiav txim.Kev khiav hauj lwm mechanism yog dav siv nyob rau hauv tag nrho cov VD4-R series circuit-breakers nrog frontal tswj.
Lub Circuit Court-breaker tuaj yeem tswj tau cov chaw taws teeb thaum haum nrog cov khoom siv hluav taws xob tshwj xeeb (gearmotor, qhib thiab kaw tso tawm).
Cov txheej txheem kev khiav hauj lwm, peb tus ncej thiab cov sensors tam sim no (yog tias muab) tau teeb tsa rau ntawm cov hlau tsis muaj lub log.Kev tsim kho tshwj xeeb yog compact, ruaj khov thiab tsis hnyav.
VD4-R series Circuit Court-breakers nrog lateral kev khiav hauj lwm mechanisms yog lub neej-ntev kaw lub siab cov cuab yeej.(IEC 62271-100)
