Ƙananan masu katsewar da'ira (MCB) galibi ana amfani da su ne don kare da'irori daga gajerun da'irori da kuma lodin kaya, kuma ana iya amfani da su a tsarin rarraba wutar lantarki don hasken wuta ko injina.
Yana da kyau da kuma ɗan ƙaramin kamanni, nauyi mai sauƙi, aiki mai kyau da aminci, ƙarfin karyewa mai yawa, saurin faɗuwa, sauƙin shigar da dogayen layukan jagora da tsawon rai.
Akwai alamomi da yawa a kan ƙaramin na'urar busar da'ira (MCB). Me suke nufi?

1. Menene ma'anar "C20"?
20 shine ƙimar wutar lantarki, to me C ke nufi? C yana wakiltar halayen girgiza kai tsaye na mai karya da'ira, wanda aka raba zuwa nau'ikan B, C da D;
Nau'in B (3-5) In yana juyawa sau 3 zuwa 5 na wutar lantarki da aka kimanta. Ya dace da nauyin juriya kawai da kuma da'irorin haske marasa ƙarfi. Wannan nau'in kayan yana da ƙaramin wutar lantarki kuma galibi ana amfani da shi a cikin hasken gida ko wurare masu buƙatar kariya mai yawa.
Nau'in C (5-10) A ciki yana juyawa sau 5 zuwa 10 na wutar lantarki da aka kimanta. Ya dace da nauyin inductive da kuma da'irorin haske masu yawan hankali, kamar fitilun halogen na tungsten. Halayen farawarsa suna da ƙimar wutar lantarki mai yawa kuma galibi ana amfani da su wajen kariyar da'irar rarrabawa. da kuma nauyin haske mai yawan hasken wuta mai yawan farawa.
Nau'in D (10-14) A ciki yana da matsala sau 10 zuwa 14 fiye da na'urar da aka kimanta. Ya dace da tsarin rarraba wutar lantarki tare da manyan nauyin inductance da manyan kwararar tasiri, kamar injina, bawuloli na solenoid da sauran kaya. Irin waɗannan kaya suna da manyan nauyin tasiri.

2.240V/400V 50Hz/60Hz yana nufin da'irori masu dacewa;
3.IEC60898 yana nufin ma'aunin lantarki na duniya IEC60898.
4. Menene ma'anar 4500A a ƙasa? Shin wutar lantarki ce?
Hakika wutar lantarki ce, wadda ke nufin matsakaicin wutar lantarki da ke karyewa. Wato, lokacin da aka samu gajeren da'ira a kan layin, idan wutar lantarki ta fi 3000A girma, ba za a iya katse ta ba. Wannan siga ta bambanta ga masana'antun daban-daban.

5. Menene ma'anar wannan alamar?
Wannan alamar tana nuna cewa na'urar yanke da'ira tana da ayyuka biyu na kariya (kariya) don ɗaukar kaya da kuma gajeren da'ira.
