Hunhu hwema "miniature circuit breakers" anogumburwa

Hunhu hwekugumburwa kwemacircuit breakersakakamurwa kuita A, B, C, D, K, nezvimwewo, uye zvazvinoreva ndeizvi:
Hunhu hweType A hwekugumburwa: simba rekugumburwa riri (2~3) In, rakakodzera kuchengetedza maseketi emagetsi e semiconductor, mitsetse yekuyera ine transformers ine simba shoma, kana masisitimu ane mitsetse mirefu uye yakadereracurrent-circuit current;
Hunhu hwerudzi rweB hwekugumburwa: simba rekugumburwa riri (3~5) In, rakakodzera masisitimu ekugovera magetsi epamba, dziviriro yemidziyo yepamba uye dziviriro yekuchengetedzwa kwemunhu;
Kugumburwa kwerudzi rweChunhu: simba remagetsi rinogumburwa riri (5-10) In, rakakodzera kuchengetedza tambo dzemagetsi dzinoshandiswa netambo dzemwenje uye mamota ane simba remagetsi rinochinja-chinja zvakanyanya;
Hunhu hwekugumburwa kwerudzi rweD: simba rekugumburwa riri (10-20) In, rakakodzera kuchengetedza michina ine simba rekugumburwa rakawanda, senge ma transformer, mavharuvhu e solenoid, nezvimwewo;
Hunhu hweK-type tripping: Ine thermal tripping action current ka1.2 uye magnetic tripping action range ka8 kusvika ku14, iyo yakakodzera kuchengetedza michina yemota uye ine kugona kwakanyanya kwekudzivirira shock current.
