Menene MCCB?
MCCB wani ɗan gajeren tsari ne don Ƙarƙashin Case Circuit Breaker.Misali ne na gama-gari na na'urar aminci ta lantarki wanda aka fi amfani da shi sau da yawa lokacin da nauyin halin yanzu ya fi girma fiye da iyakar ƙaramar na'urar da'ira.
MCCB yana ba da kariya daga gajerun kurakuran da'ira kuma ana amfani da ita don sauya da'irori.Ana iya amfani da shi don mafi girman ƙimar halin yanzu da kuma matakin kuskure, a cikin yanayin wasu dalilai na gida.Faɗin ƙima na yanzu da babban ƙarfin karyewa a cikin Mai Rarraba Case Circuit Breaker yana nufin cewa sun dace da dalilan masana'antu.
Ta yaya MCCB ke aiki?
MCCB tana amfani da na'urar da ke da zafin jiki (ma'auni na thermal) tare da na'urar lantarki ta halin yanzu (nau'in maganadisu) don samar da hanyar tafiya don kariya da dalilai keɓewa.Wannan yana bawa MCCB damar samar da:
