Kodi ma contact a MCCB amapangidwa ndi zinthu ziti?

Zinthu zolumikizirana zachotsukira dera chopangidwa ndi bokosiMakamaka ndi siliva alloy, yomwe ili ndi mphamvu yabwino yoyendetsera magetsi, kukana kuvala komanso kukhazikika kwa kutentha. Zolumikizirana zasiliva alloy nthawi zambiri zimagwiritsidwa ntchito kuti zitsimikizire kuti ma circuit breaker amagwira ntchito bwino komanso kuti azigwira ntchito nthawi yayitali. Zida zina zolumikizirana zomwe zimagwiritsidwa ntchito nthawi zambiri ndi monga mkuwa, tungsten alloy ndi chromium copper. Zipangizozi zimagwiritsidwa ntchito mu ma circuit breaker amitundu yosiyanasiyana komanso ntchito zake chifukwa cha mphamvu yawo yabwino yoyendetsera magetsi, kukana kuvala komanso kukana kutentha kwambiri.

Gulu la Mutai lili ndi zaka zoposa khumi zogwira ntchito yopanga ndi kugulitsa zinthu zosiyanasiyana monga ma circuit breakers, ma contactors, ma dual power automatic transfer switches (ATS), ndi zina zotero. Tikuyembekezera mwachidwi mwayi wogwirizana nanu.
