I-Insulation Voltage kunye ne-Impulse Standstand

Amandla ombane wokugquma (Ui) we-1000V kunye nesantya sokumelana namandla ombane (Uimp) angama-4000V agxininisa amandla e-MCB okumelana noxinzelelo lombane, ebonelela umaleko owongezelelweyo wokomelela kwiimeko ezahlukeneyo zokusebenza.

IKlasi yokuMisela yangoku 3

Ihlelwe njengesixhobo sokunciphisa i-Class 3 yangoku, ezi MCB zigqwesa ekunciphiseni umonakalo onokwenzeka xa kukho impazamo. Esi sixhobo sibalulekile ekukhuseleni izixhobo ezisezantsi kunye nokugcina imfezeko yesixokelelwano sombane.

IFuse eKhethekileyo yokuGcina

Ixhotyiswe nge-back-up fuse ebonisa ukukhetha okuphezulu, ezi MCBs ziqinisekisa ukuba zivumela amandla aphantsi. Oku akugcini nje ukwandisa ukukhuselwa kwenkqubo kodwa kunegalelo ekuthembekeni ngokubanzi kokuseta umbane.

Isalathisi seNdawo yoQhagamshelwano

Umsebenzisi-umsebenzisi obomvu-oluhlaza obonisa indawo yoqhagamshelwano ebonisa isibonakaliso esicacileyo esibonakalayo, esikuvumela ukuba ujonge ngokulula isimo somqhekezi. Olu phawu lulula kodwa lusebenzayo longeza umaleko owongezelelweyo wokwenza lula kubaqhubi.

Uluhlu olubanzi lweeNqanawa eziRayilwayo

Ezi MCBs zithatha uluhlu oluhlukeneyo lwamanzi alinganisiweyo, kunye neendlela ezifikelela kwi-63A. Oku bhetyebhetye kubenza bakwazi ukuhlangabezana neemfuno zomthwalo ohlukeneyo wezicelo ezahlukeneyo, zongeza ukuguquguquka kusetyenziso lwabo.
