Hobaneng u Khetha CDADA MCCB ka Tšireletso ea Leakage?

★ Tšireletso ea 'Nete e Kopanetsoeng

Ho fapana le li-module tsa RCD tsa tlatsetso, DAM1L e na le ts'ireletso ea ho lutla e hahelletsoeng ke fektheri-ho netefatsa tšebelisano e phethahetseng le ho felisa litaba tsa ho lumellana.

★ Multi-Phase Power bakeng sa RCD Circuit

Li-RCD tsa pele li ile tsa hlōleha haeba karolo e le 'ngoe e lahlehile. Moqapi oa CDADA o sebelisa mekhahlelo eohle ho matlafatsa lisebelisoa tsa elektroniki tsa ts'ireletso, ka hona e lula e sebetsa le nakong ea tahlehelo ea mokhahlelo kapa ho senyeha ho hoholo ha motlakase.

★ Lipakane tsa Tšireletso tse peli ho Sesebelisoa se le seng

◆ 30mA: E finyella litlhoko tsa IEC bakeng sa ts'ireletso ea motho ka mong

◆ 100mA–1000mA: E thibela mollo o senyang oa ho kenya letsoho ho tsoa mefokolong e menyenyane, e sa khaotseng ea fatše.

★ Field-Adjustable for Real-World Conditions

Boikutlo bo botle le ho lieha ha nako ho qoba ho khoptjoa ke tšitiso libakeng tse mongobo (mohlala, ho hlatsoa likoloi, mapolasi) ha u ntse u boloka tšireletso.

★ Tšepahalang ea Kereiti ea Liindasteri

Boemo bo phahameng ba ho robeha (H-mofuta), karohano e matla ea arc, le tšireletso ea IP20+ e etsa hore e tšoanelehe bakeng sa maemo a thata a khoebo le a indasteri.

Q1: Ke phapang efe pakeng tsa MCCB e tloaelehileng le MCCB e nang le tšireletso ea ho lutla?

A1: MCCB e tloaelehileng e sireletsa feela khahlanong le boima bo feteletseng le li-circuits tse khutšoanyane. DAM1L e eketsa mokhoa o setseng oa ho lemoha (ho lutla ha lefatše) - ho khoptjoa ha hona joale ho lutla fatše (mohlala, ka motho kapa ho senya ho senyehileng), ho thibela ho tsosoa ha motlakase kapa mollo.

Q2: Na nka sebelisa 100A MCCB RCD bakeng sa tšireletso ea botho?

A2: Ha feela e setiloe ho 30mA. Hona joale e lekantsoeng (100A) e hlalosa matla a mojaro; sebaka se setseng (I△n) se hlalosa ts'ebetso ea polokeho. Bakeng sa ts'ireletso ea ts'ireletso, I△n e tlameha ho ba ≤30mA, ho sa tsotelehe In.

Q3: Ke hobane'ng ha potoloho ea RCD e hloka matla a mekhahlelo e mengata?

A3: Haeba e tsamaisoa ke mohato o le mong feela, ho hloleha ha karolo e le 'ngoe ho ka tima ts'ireletso ea ho lutla. Moqapi oa mekhahlelo e mengata oa CDADA o etsa bonnete ba hore RCD e lula e sebetsa esita le nakong ea tahlehelo ea mekhahlelo kapa matla a tlaase (ho fihlela ho 50V) -a bohlokoa bakeng sa ts'ireletso ea ts'ireletso.

Q4: Na 4P leakage MCCB e loketse lits'ebetso tsa TT kapa TN-S?

A4: E-e etselitsoe litsamaiso tsa TT, TN-S, le IT. Moralo oa 4P o roba mekhahlelo eohle ebile o sa nke lehlakore, o bohlokoa bakeng sa lits'ebetso tsa TT moo ho se nke lehlakore ho sa theoheng holimo.

Q5: Ke hobane'ng ha u khetha CDADA holim'a motsoako oa modular RCD + MCCB?

A5: CDADA DAM1L e fana ka:

● Melato e menyenyane (e kopantsoeng khahlanong le lisebelisoa tse peli)

● Khokahano e tiisitsoeng (ha ho kotsi e fapaneng)

● Theko e tlase & ho rarahana ha lithapo

● Ho tšepahala ho hoholo (yuniti e tiisitsoeng e le 'ngoe)

● Ho feto-fetoha ha setšeng ha ho khonehe ka li-RCD tse sa fetoheng
