Tuam Tshoj VD4 series nqus Circuit Court-breakers yog cov khoom siv rau sab hauv tsev switchgear installation.Thov hu rau ROCKWILL rau cov kev cai tshwj xeeb rau kev teeb tsa.VD4-R series nruab nrab voltage nqus Circuit Court breakers nrog lateral kev khiav hauj lwm mechanism rau sab hauv tsev installation feature lub cais ncej tsim txheej txheem.Txhua tus ncej muaj lub tshuab nqus tsev cuam tshuam uas tau ntim rau hauv cov cob thaum lub tog raj kheej molded ua tsaug rau cov txheej txheem tsim tshwj xeeb.Txoj kev tsim kho no tiv thaiv lub tshuab nqus tsev cuam tshuam los ntawm kev poob siab, muaj kuab paug thiab condensation.
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)
