Chii chinonzi MCB?
Miniature Circuit Breaker (MCB) imhando yedunhu rinotyora iro diki muhukuru.Inobva yacheka kutenderera kwemagetsi panguva ipi zvayo isina kunaka mumagadzirirwo emagetsi ekupa magetsi, zvakadai sekuwedzera kwepamusoro kana kuti pfupi-circuit current.Kunyangwe mushandisi anogona kuseta zvakare MCB, fuse inogona kuona aya mamiriro, uye mushandisi anofanira kuitsiva.
Iyo MCB chishandiso chemagetsi chinodzivirira waya dzemagetsi uye mitoro kubva kune inrush current, kudzivirira moto uye dzimwe njodzi dzemagetsi.MCB yakachengeteka kubata, uye inotora simba nekukurumidza.Zvekuremedza uye zvenguva pfupi yedziviriro yedunhu mumashandisirwo ekugara, iyo MCB ndiyo inonyanya kufarirwa sarudzo.MCBs dzinokurumidza kugadzirisa zvakare uye hazvidi gadziriso.Iyo bi-simbi inopindirana pfungwa inoshandiswa muMCBs kudzivirira kubva pakufashukira ikozvino uye pfupi dunhu razvino.
