RCBOke khutsufatso ea "overcurrent residual current circuit breaker" 'me ke sesebelisoa sa bohlokoa sa polokeho ea motlakase se kopanyang mesebetsi ea MCB (miniature circuit breaker) le RCD (sesebelisoa se setseng sa hona joale).E fana ka tšireletso khahlanong le mefuta e 'meli ea liphoso tsa motlakase: overcurrent le residual current (eo hape e bitsoang leakage current).

Ho utloisisa joangRCBOsebetsa, a re ke re pele ka potlako hlahloba mefuta ena e 'meli ea ho hlōleha.

Overcurrent e etsahala ha metsi a mangata haholo a phalla ka har'a potoloho, e leng se ka bakang mocheso o feteletseng le mohlomong esita le mollo.Sena se ka etsahala ka mabaka a fapaneng, joalo ka potoloho e khuts'oane, overload ea potoloho, kapa phoso ea motlakase.Li-MCB li etselitsoe ho lemoha le ho sitisa liphoso tsena tse fetelletseng ka ho khoptjoa ke potoloho hang ha motlakase o feta moeli o reriloeng esale pele.

Ka lehlakoreng le leng, metsi a setseng kapa a lutla a etsahala ha potoloho e sitisoa ka phoso ka lebaka la ho se sebetse hantle kapa kotsi ea DIY.Ka mohlala, u ka 'na ua phunyeletsa ka thapo ka phoso ha u ntse u kenya hook ea litšoantšo kapa ua e khaola ka mochini o kutang mohloa.Tabeng ena, motlakase o ka 'na oa lutla tikolohong e potolohileng, e leng se ka bakang ts'oaetso ea motlakase kapa mollo.Li-RCD, tse tsejoang hape e le GFCIs (Ground Fault Circuit Interrupters) linaheng tse ling, li etselitsoe ho bona ka potlako maqhubu a lutla a motsotsoana le ho theola potoloho ka har'a milliseconds ho thibela kotsi efe kapa efe.

Joale, ha re shebisiseng hore na RCBO e kopanya bokhoni ba MCB le RCD joang.RCBO, joalo ka MCB, e kentsoe ka har'a switchboard kapa yuniti ea bareki.E na le mojule oa RCD o hahelletsoeng o lulang o lekola lebelo la hona joale le potolohang.

Ha phoso e fetelletseng e etsahala, karolo ea MCB ea RCBO e lemoha hona joale e feteletseng 'me e tsamaea le potoloho, kahoo e sitisa phepelo ea motlakase le ho thibela kotsi leha e le efe e amanang le ho tlala kapa potoloho e khutšoanyane.Ka nako e ts'oanang, mochine oa RCD o hahiloeng ka hare o lekola tekanyo ea hona joale pakeng tsa lithapo tse phelang le tse sa jeleng paate.

Haeba ho na le masala a teng (ho bonts'a phoso ea ho lutla), karolo ea RCBO ea RCD hang-hang e khoehlisa potolohong, kahoo e hakolla phepelo ea motlakase.Karabelo ena e potlakileng e etsa bonnete ba hore ts'ebetso ea motlakase e ea qojoa 'me mollo o ka bang teng oa thibeloa, ho fokotsa kotsi ea liphoso tsa mohala kapa ho senyeha ha cable ka phoso.

Ho bohlokoa ho ela hloko hore RCBO e fana ka ts'ireletso ea potoloho ea motho ka mong, ho bolelang hore e sireletsa lipotoloho tse ikhethileng ka har'a moaho tse ikemetseng, joalo ka li-circuits kapa li-outlet.Tšireletso ena ea modular e thusa ho lemoha liphoso tse lebisitsoeng le ho itšehla thajana, ho fokotsa tšusumetso ho lipotoloho tse ling ha phoso e etsahala.

Ho akaretsa, RCBO (overcurrent residual current circuit breaker) ke sesebelisoa sa bohlokoa sa polokeho ea motlakase se kopanyang mesebetsi ea MCB le RCD.E na le ts'ireletso ea morao-rao le ts'ebetso e setseng ea ts'ireletso ho netefatsa polokeho ea motho le ho thibela likotsi tsa mollo.Li-RCBO li bapala karolo ea bohlokoa ho bolokeng polokeho ea motlakase malapeng, meahong ea khoebo le tikolohong ea indasteri ka ho khoptjoa ka potlako lipotolohong ha ho fumanoa phoso efe kapa efe.
