Izaphuli zesekethe ze-Knob kunye ne-toggle circuit breakers (ngamanye amaxesha zibizwa ngokuba yi-rotary toggle switches kunye ne-push-button toggle switches) zintlobo ezimbini eziqhelekileyo zokutshintsha kwiinkqubo zombane, nganye ineempawu ezizodwa kunye neemeko ezisebenzayo.
Izaphuli zesekethe zeKnob zisebenzisa iknobhu ejikelezayo ukulawula ukuphuma nokuvula isekethe. Olu hlobo lokutshintsha luhlala lusetyenziswa kwiimeko apho ngoku kufuneka kulawulwe ngokuchanekileyo, njengezikhululo zokuhambisa amandla kunye neebhubhoratri. Inzuzo ye-knob circuit breaker kukuba inokuchaneka okuphezulu kohlengahlengiso. Abasebenzisi banokuhlengahlengisa ngokuchanekileyo ngoku ngokujikeleza i-knob ukuqinisekisa ukusebenza okuqhelekileyo kwezixhobo kunye nokuchaneka kweziphumo zovavanyo. Ukongeza, i-knob circuit breaker iya kuhamba ngokuzenzekelayo xa isekethe ingaphumeleli okanye ilayishwe kakhulu, inqumle ukunikezelwa kwamandla ukukhusela ukhuseleko lwezixhobo kunye nabasebenzi. Kulula ukuyisebenzisa, ayifuni amagcisa aqeqeshiweyo ukuba asebenze, kwaye ineendleko eziphantsi ngokwentelekiso. Ngokukodwa kwezinye izixhobo zombane ezincinci, ukusetyenziswa kwe-knob circuit breaker kunokunciphisa ngokufanelekileyo iindleko. Nangona kunjalo, kwimeko engxamisekileyo, isantya sokusebenza kwe-knob circuit breaker asikwazi ukukhawuleza njenge-push-button circuit breaker.
I-toggle circuit breaker (i-push-button type) itshintsha imeko yesekethe ngokucofa iqhosha. Olu hlobo lokutshintsha luhlala lusetyenziselwa ukulawula imisinga emincinci kunye nee-voltages, ezifana nokutshintsha kunye nezibane zesalathisi zezixhobo zombane. Inzuzo ye-push-button circuit breakers kukuba kulula ukuyisebenzisa kwaye iphendule ngokukhawuleza, okwenza ukuba ifaneleke kakhulu kwiimeko apho amandla kufuneka anqunyulwe ngokukhawuleza, njengamaqhosha okumisa ngokukhawuleza kwimigca yokuvelisa kunye neenkqubo zokudibanisa i-alamu yomlilo kwiindawo zoluntu. Kwezi meko, ixesha bubomi, kwaye i-push-iqhosha lesekethe i-breakers inokukhawuleza ukunqumla amandla kunye nokunciphisa ingozi enokubakho. Ukongeza, i-push-button breaker circuits ngokuqhelekileyo inamanqaku esalathisi esicacileyo, njengombala obomvu wokuqhawula kunye nohlaza ukudibanisa, okwenza kube lula kubasebenzisi ukuchonga ngokukhawuleza imeko yangoku.
Ngokuphathelele ukuba yeyiphi ifom ye-circuit breaker ingcono, ixhomekeke kwimeko yesicelo esithile kunye neemfuno. Abaphuli beesekethe zohlobo lwe-Knob benza ngcono kwiimeko apho kufuneka ulawulo oluchanekileyo lobungakanani bangoku kunye nokuchaneka kohlengahlengiso, ngelixa i-push-button breakers inenzuzo ngakumbi kwiimeko apho amandla kufuneka anqunyulwe ngokukhawuleza kwaye kufuneka imisebenzi kaxakeka. Ngoko ke, xa ukhetha i-breaker circuit, abasebenzisi kufuneka benze ingqwalasela ebanzi ngokusekelwe kwiimfuno zangempela kunye nemeko yokusetyenziswa.
Ngokubanzi, i-knob-type circuit breakers kunye ne-toggle-type-break breakers nganye ineenzuzo zayo ezizodwa kunye neemeko ezisebenzayo. Xa uyila kunye nokukhetha inkqubo yombane, uhlobo olufanelekileyo lwe-circuit breaker kufuneka lukhethwe ngokwemeko yangempela ukuqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo kwenkqubo yamandla. Ngexesha elifanayo, kungakhathaliseki ukuba luhlobo luni lwe-circuit breaker olukhethiweyo, umgangatho walo kunye nokusebenza kufuneka kuqinisekiswe ukuhlangabezana nemigangatho efanelekileyo kunye neemfuno.
