Makhalidwe opunthwa a ma miniature circuit breakers

Makhalidwe a kugwedezeka kwazosokoneza ma circuitZigawidwa m'magulu A, B, C, D, K, ndi zina zotero, ndipo matanthauzo ake ndi awa:
Makhalidwe a kugwedezeka kwa Mtundu A: mphamvu yogwedezeka ndi (2 ~ 3) In, yoyenera kuteteza ma setiweki amagetsi a semiconductor, mizere yoyezera yokhala ndi ma transformer amphamvu ochepa, kapena machitidwe okhala ndi mizere yayitali komanso yotsikakufupikitsamphamvu yamagetsi;
Makhalidwe a kugwedezeka kwa mtundu wa B: mphamvu yogwedezeka ndi (3 ~ 5) In, yoyenera machitidwe ogawa magetsi apakhomo, chitetezo cha zida zapakhomo ndi chitetezo cha munthu payekha;
Makhalidwe a kugwedezeka kwa mtundu wa C: mphamvu yogwedezeka ndi (5-10) In, yoyenera kuteteza mizere yogawa magetsi ndi mizere yowunikira ndi ma motor circuits okhala ndi mphamvu yosinthira kwambiri;
Makhalidwe a kugwedezeka kwa mtundu wa D: mphamvu yogwedezeka ndi (10-20) In, yoyenera kuteteza zida zokhala ndi mphamvu yothamanga kwambiri, monga ma transformer, ma solenoid valves, ndi zina zotero;
Makhalidwe a K-type tripping: Ili ndi mphamvu ya kutentha yochulukitsa nthawi 1.2 kuposa mphamvu yamagetsi yochulukitsa komanso nthawi 8 mpaka 14 kuposa mphamvu yamagetsi yochulukitsa, yomwe ndi yoyenera kutetezazida zoyendera motandipo ili ndi mphamvu yayikulu yolimbana ndi kugwedezeka kwamphamvu
