MCCB -ihe mgbaji sekit kpụrụ akpụ- bụ ngwaọrụ nchebe dị ala nke na-ewepụ sekit na-akpaghị aka mgbe ọ chọpụtara oke ibu ma ọ bụ ọnọdụ mkpirisi. N'adịghị ka fuse, enwere ike ịtọgharịa ma jiri ya mee ihe mgbe njem gasịrị. N'ime akpa ahụ a kpụrụ akpụ, usoro njem ọkụ magnetik na-arụ ọrụ abụọ: ihe ọkụkụ na-anabata oke ibu, ebe ihe ndọta na-eme ozugbo maka mmejọ mkpirisi okirikiri. Ihe si na ya pụta bụ nchebe nke dabara ka ezigbo ibu eletrik si akpa àgwà.

Mgbe ịhọrọ MCCB: ndị na-enye nri ndị na-abata, akụkụ nkesa nke ụzọ atọ, nnukwu sekit moto, ma ọ bụ ebe ọ bụla ebe enwere mkpirisi okirikiri ugbu a karịrị ihe MCB nwere ike ịkwụsị.
