MCCB ke eng?

MCCB ke mofuta o mokhuts'oane oa Molded Case Circuit Breaker.Ke mohlala o tloaelehileng oa sesebelisoa sa tšireletso ea motlakase se atisang ho sebelisoa ha moroalo oa hona joale o phahame haholo ho feta moeli oa mochine o monyenyane oa potoloho.

MCCB e fana ka tšireletso khahlanong le liphoso tsa potoloho e khuts'oane ebile e sebelisetsoa ho fetola lipotoloho.E ka sebelisoa bakeng sa litekanyetso tse phahameng tsa hajoale hammoho le boemo ba liphoso, molemong oa merero e 'maloa ea lapeng.Litekanyetso tse pharaletseng tsa hajoale le bokhoni bo phahameng ba ho robeha ho Molded Case Circuit Breaker li bolela hore li loketse le mabaka a indasteri.

MCCB e sebetsa joang?

MCCB e sebelisa sesebelisoa se hlokomelang mocheso (thermal element) se nang le sesebediswa sa morao-rao sa motlakase (sesebediswa sa makenete) ho fana ka mochini oa maeto bakeng sa ts'ireletso le merero ea ho itšehla thajana.Sena se nolofalletsa MCCB ho fana ka:
