Iimpawu zokukhubeka kwee-miniature circuit breakers

Iimpawu zokukhubekaiziphuli zesekethezahlulwe ngo-A, B, C, D, K, njl., kwaye intsingiselo yazo yile ilandelayo:
Iimpawu zokukhubeka kohlobo A: umsinga wokukhubeka yi (2~3) In, ifanelekile ukukhusela iisekethe ze-elektroniki ze-semiconductor, imigca yokulinganisa ene-transformers zamandla aphantsi, okanye iinkqubo ezinemigca emide kunye ne-lowintambo emfutshaneumsinga;
Iimpawu zokukhubeka kohlobo B: umsinga wokukhubeka ngu (3~5) In, ofanelekileyo kwiinkqubo zokusasazwa kwamandla endlu, ukhuseleko lwezixhobo zasekhaya kunye nokhuseleko lomntu;
Iimpawu zokukhubeka kohlobo lwe-C: umsinga wokukhubeka yi-(5-10) In, efanelekileyo ukukhusela imigca yokusasazwa kwamandla kunye nemigca yokukhanyisa kunye neesekethe zeemoto ezine-current yokutshintsha ephezulu;
Iimpawu zokukhubeka kohlobo lwe-D: umsinga wokukhubeka ngu-(10-20) In, ofanelekileyo ukukhusela izixhobo ezine-inrush current ephezulu, ezifana nee-transformers, ii-solenoid valves, njl.njl.;
Iimpawu zokukhubeka kohlobo lwe-K: Inomlinganiselo wesenzo sokukhubeka kobushushu ophindwe ka-1.2 kunye nomlinganiselo wesenzo sokukhubeka kombane ophindwe ka-8 ukuya ku-14, ofanelekileyo ukukhuselaizixhobo zesekethe yemotokwaye inamandla aphezulu okulwa noxinzelelo lwamandla
