I-MCB lock off, eyaziwa ngokuba sisixhobo sokutshixa i-MCB, njengoko igama layo libonisa, isetyenziselwa ukutshixa i-1P eqhelekileyo, i-2P kunye ne-multipole miniature breakers kwimarike, njenge-C45, i-DZ47, njl. phantse iwaka leentlobo zezaphuli zesekethe.Ngokutsho kwesakhiwo esahlukileyo sinokuthi sivela kwi-pin ukuya kuhlobo lwangaphakathi, i-pin ukuya kuhlobo lwangaphandle, uhlobo lwe-screw, uhlobo lwendalo yonke kunye nezinye iintlobo ezahlukeneyo kunye neenkcukacha ze-MCB yokutshixa ukhuseleko ukukhetha isitshixo esifanelekileyo sokhuseleko.

Imodeli yesixhobo sokutshixa i-MCB kunye nendlela yokusebenzisa

Uhlobo lweqhosha lokucofa: kukho iindidi ezintathu: pin, qhobosha kwaye cinezela ngokubanzi;Kwiziphazamisi zesekethe ezincinci ezinemingxuma kumacala omabini esiphatho, ngaphandle kwezixhobo, cinezela nje iqhosha ukufaka izikhonkwane ezimbini ezisezantsi kwimingxuma emibini ye-breaker circuit, uze ubophe i-padlock kunye nethegi yokhuseleko;
Uhlobo lwe-tie-rod: lufanelekile kwi-single-pole kunye ne-multi-pole circuit breakers;Ngexesha lofakelo, isitshixo sokhuseleko se-breaker sesekethe sinokunyanzeliswa ngokuqinileyo kwintonga yokutsala ngokulula ngokuqinisa i-screw self-screw emnyama kwaye emva koko ufake i-padlock yokukhusela ukukhusela isixhobo sokubamba ukuba sikhululeke;
Uhlobo lwe-Screw: i-MCB yokutshixa i-slot ibambelele kwisiphatho se-breaker yesiphaluka, emva koko uyijije phantsi nge-screwdriver ukuze ibambelele ngokuqinileyo kwi-handle, uze ufake i-padlock yokhuseleko;Kukwasebenza nakwi-single-pole okanye kwi-multipole circuit breaker, ziyasebenza ukwahlula phakathi kwe-miniature circuit breaker kunye ne-molded case circuit breaker;
Uhlobo lwe-self-screw: olufana nohlobo lwe-screw-screw lunamathele kwi-handle ye-breaker circuit.Ngenxa yentloko ye-self-screw, inokuqiniswa ngaphandle kwe-screwdriver.
