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 yakadererakupfupisa kwedunhumagetsi;
Hunhu hwerudzi rweB hwekugumburwa: simba rekugumburwa riri (3~5) In, rakakodzera masisitimu ekugovera magetsi epamba, dziviriro yemidziyo yepamba uye dziviriro yekuchengetedzwa kwemunhu;
Hunhu hweC-type tripping current: tripping current iri (5-10) In, yakakodzera kuchengetedza tambo dzemagetsi netambo dzemwenje nemota dzine high switching current;
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 1.2 nguva yekupisa tripping action current uye 8 kusvika 14 nguva yemagnetic tripping action range, iyo yakakodzera kudziviriramidziyo yedunhu remotauye ine kugona kwakanyanya kwekudzivirira kuvhunduka
