Nyeoe tsa Kopo ea RDM5 Series 250A/400A/630A
RDM5-250 (Foreimi ea 250A)
● Lekanyetsoa hona joale: 100–250A
● Bokgoni ba ho roba (AC400V): Icu 35–50kA, Ics 25–35kA
● Ditshebediso tse tlwaelehileng: Kabo ya makala difekthering tse nyane le tse mahareng, dienjene tsa mekhahlelo e meraro (fene, dipompo, dikompressor tsa moya), diteishene tse nyane tsa mofuta wa lebokose la PV
● Malebela a ho khetha: Pele ho 3P/4P e nang le tokollo ea motlakase-makenete; mofuta oa tšireletso ea enjene bakeng sa meroalo ea enjene, e nang le likhokahano tsa thuso/alamu tse ikhethileng.
RDM5-400 (Foreimi ea 400A)
● Lekanyetsoa hona joale: 200–400A
● Bokgoni ba ho roba (AC400V): Icu 50–70kA, Ics 35–50kA; Icu 20–25kA ho AC690V
● Lisebelisoa tse tloaelehileng: Kabo e kholo lithupelong, litsi tsa data tse mahareng, li-switch tse kholo mehahong ea khoebo
● Malebela a ho kgetha: 3P/4P e kgothaletswang ka mofuta wa M (ho robeha ho mahareng); mofuta wa H o robehang haholo bakeng sa ditsamaiso tse kgolo, ka ho lokollwa ha shunt/undervoltage bakeng sa tshireletso ya remoutu le undervoltage.
RDM5-630 (Foreimi ea 630A)
● Lekanyetsoa hona joale: 400–630A
● Bokgoni ba ho roba (AC400V): Icu 50–100kA, Ics 50–75kA; Icu 20–35kA ho AC690V
● Lisebelisoa tse tloaelehileng: Lisebelisoa tse kholo tse kenang, li-substation tse nang le motlakase o tlase, lipotoloho tsa li-coupler tsa libese tsa indasteri
● Malebela a ho khetha: Pele ho 3P/4P e nang le bokgoni ba ho roba bo phahameng ba mofuta wa H; dikgokelo tsa bohlokwa tsa thuso/alamu bakeng sa dipotoloho tsa bohlokwa, tse fumanehang ka mefuta e tsitsitseng le e hulang.
Kakaretso ea Khetho e Potlakileng
● 250A: Mejaro e menyenyane le e mahareng / kabo ea makala → RDM5-250
● 400A: Kabo e mahareng ea mantlha / sesebelisoa se seholo sa moaho → RDM5-400
● 630A: Dipotoloho tse kgolo tse kenang/tse mahlonoko tse nang le motlakase o phahameng → RDM5-630
Khetho e felletseng le e lumellanang e ka etsoa ka mehato e meraro:hajwale e lekantsweng ka ho lekana → netefatsa bokgoni ba ho roba → kgetha dipalo le disebediswa.
