♦ Ntchito yomanga SAS7Modular Magnetic Circuit Breakerndi amtundu wochepetsera matenthedwe wapano wa matenthedwe, okhala ndi kamangidwe kakang'ono komwe kwatheka osati kuchepetsa kuchuluka kwa magawo komanso kuchuluka kwa zolumikizira zowotcherera ndi zolumikizira.

♦Kusankha kwazinthu zofunikira kumatsimikizira kudalirika ndi kukhazikika.

♦ Chofanana ndi ichi ndi kusankha kwa graphite ya siliva kwa kukhudzana kokhazikika. MCB ili ndi chogwirizira chosavuta kugwiritsa ntchito ndi makina osinthira opanda maulendo - kotero ngakhale chogwiriracho chili pamalo pomwe MCB imayambiranso.

Kuganizira kutentha kozungulira

SAS7Modular Magnetic Circuit Breakeramayesedwa kuti akwaniritse zofunikira za IECBSEN60898.2 VB8035 Ref Calibration Temperature. Pa kutentha kwina, zotsatirazi ziyenera kugwiritsidwa ntchito.

Ma MCB oyandikana ndi maginito otenthetsera sayenera kukwezedwa mosalekeza kapena kuyandikira mafunde awo odziwika ngati atayikidwa m'mipanda. Ndibwino kuchita uinjiniya kugwiritsa ntchito zinthu za gererous de-rating kapena kupereka mpweya wokwanira pakati pa zida. Muzochitika izi, komanso zofanana ndi opanga ena, timalimbikitsa kuti 66% yamitundu yosiyanasiyana igwiritsidwe ntchito ku MMCB yomwe idavotera panopa pomwe cholinga chake ndi kuyika MMCB mosalekeza (kupitirira ola limodzi).
