1. Matla a phahameng a ho senya
Li-MCCB li na le matla a holimo a ho robeha, e leng palo e phahameng ea nako eo li ka e sitisang ka mokhoa o sireletsehileng.Li-MCCB li na le matla a ho pshatla haholo 'me li khona ho sebetsana le maqhubu a nako e khuts'oane ho fihla ho mashome a kiloamperes (kA).Sena se bolela hore ba ka arola liphoso kapele le ho thibela tšenyo ea lisebelisoa le lisebelisoa tse tlase.Bokhoni bo phahameng ba ho robeha bo boetse bo bolela hore li-MCCB li khona ho jara meroalo e meholo, e nolofalletsang lisebelisoa tsa motlakase ho sebetsa maemong a phahameng a matla.
2. Litlhophiso tse loketseng tsa leeto
MCCB e na le litlhophiso tse feto-fetohang tsa maeto tse e lumellang ho hlophisoa ho latela litlhoko tse ikhethileng tsa ts'ebeliso.Litlhophiso tsena li tloha ho li-unit tsa maeto a khoheli ho ea ho li-unit tsa maeto a elektroniki, 'me li lumella MCCB ho arabela maemong a fapaneng a nako e telele joalo ka potoloho e khuts'oane kapa ho tlala.U sebelisa MCCB, basebelisi ba ka hlophisa litlhophiso hantle ho fana ka boemo bo lakatsehang ba ts'ireletso le ho ntlafatsa ts'ebetso ea sistimi ea bona ea motlakase.
3. Tšireletso ea makenete ea mocheso
Li-MCCB li fana ka motsoako oa tšireletso ea mocheso le makenete.Likarolo tsa maeto a tšireletso ea mocheso li arabela linthong tse ngata haholo, ha likarolo tsa tšireletso tsa makenete li arabela liseketeng tse khutšoane.Mokhoa oa leeto o arabela haholo 'me o tla nka khato ka potlako ho latela boemo ba overcurrent.Ha MCCB e kenngoa, tsamaiso ea motlakase e rua molemo ho tsoa ts'ireletso e tsoetseng pele khahlanong le tšenyo ea mocheso le ea makenete.

5. Bokhoni bo ntlafetseng ba ho beha leihlo le ho buisana
Li-MCCB tsa sejoale-joale li kenyelletsa theknoloji e tsoetseng pele ea microprocessor, e li nolofalletsang ho buisana le lisebelisoa le lits'ebetso tse ling.Li-MCCB li beha leihlo le ho rekota liparamente tse kang tsa hajoale, motlakase, matla le tšebeliso ea matla, ho thusa basebetsi le baenjiniere ho lekanya bophelo bo botle ba lits'ebetso tsa motlakase.Ho feta moo, bokhoni ba puisano bo thusa li-MCCBs ho hokahana le lits'ebetso tsa ho beha leihlo, taolo le boiketsetso, ho ntlafatsa taolo ea sistimi ea motlakase le ts'ebetso.
6. E matsutla-tsutla ebile e ka tšeptjoa
Li-MCCB li etselitsoe ho mamella maemo a thata 'me li ka sebetsa ka mocheso ho tloha ho -25°C ho ea +70°C.Li entsoe ka thepa ea boleng bo phahameng e hanyetsanang le liaparo tsa lik'hemik'hale le tsa mechine, tse kang polycarbonate, polyester le ceramic.Ho phaella moo, li-MCCB li phela nako e telele haholo, li nka lilemo tse 10 ho isa ho tse 20 ho itšetlehile ka tšebeliso ea tsona le tlhokomelo.
7. Kopo e sebetsang ka bongata
Li-MCCB li na le mefuta e mengata ea lits'ebetso, ho tloha ho matla a tlase ho isa ho litsamaiso tse phahameng tsa motlakase.Ke karolo ea bohlokoa ea ho sireletsa le ho laola li-motor, lijenereithara, li-transformer le lisebelisoa tse ling tsa bohlokoa tsa motlakase.Li-MCCB le tsona ke moeli oa pele oa ts'ireletso bakeng sa ho aha lisebelisoa tsa motlakase, li-substations, indasteri e boima le limela tsa motlakase.
