♦Ulwakhiwo lweSAS7Isixhobo sokwaphula isekethe seMagnetic esiModularzezohlobo lokunciphisa ubushushu be-thermal-magnetic current, zinesakhiwo esincinci esifezekisiweyo kungekuphela nje ngokunciphisa inani leendawo kodwa kunye nenani lamalungu kunye noqhagamshelo oludibeneyo.

♦Ukukhethwa kwezinto ezibalulekileyo kuqinisekisa ukuthembeka nokuqina.

♦Isiqhelo sale nto kukukhetha i-graphite yesilivere yokudibanisa okuzinzileyo. I-MCB inesiphatho esilula ukusisebenzisa esinendlela yokutshintsha engenamagingxigingxi-ngoko ke nokuba isiphatho sibanjwe kwindawo ebekwe kuyo i-MCB ikulungele ukushukuma.

Izinto eziqwalaselwayo malunga nobushushu obuphakathi

I-SAS7 Modular Magnetic Circuit Breaker ilinganiswe ukuze ihlangabezane neemfuno ze-IECBSEN60898.2 VB8035 Ref Calibration Temperature. Kwamanye amaqondo obushushu, kufuneka kusetyenziswe ezi zinto zilandelayo zokurhawuzelela.

Ii-MCB ezikufutshane ezisebenzisa ubushushu akufuneki zihlale zilayishwa okanye zisondele kwi-nominal rated currents xa zifakelwe kwiindawo ezibiyelweyo. Yindlela elungileyo yobunjineli ukusebenzisa izinto ezinciphisa umlinganiselo okanye ukwenza amalungiselelo omoya okhululekileyo phakathi kwezixhobo. Kwezi meko, kwaye ngokufanayo nabanye abavelisi, sicebisa ukuba i-66% diversity factor isetyenziswe kwi-nominal rated current ye-MMCB apho yenzelwe ukulayisha i-MMCB rhoqo (ngaphezulu kweyure e-1).
