Yintoni i-MCB?
I-Miniature Circuit Breaker (MCB) luhlobo lwe-circuit breaker encinci ngobukhulu.Ngokukhawuleza inqumla isiphaluka sombane ngexesha layo nayiphi na imeko engafanelekanga kwiinkqubo zokubonelela ngombane, njenge-overcharge okanye i-short-circuit current.Nangona umsebenzisi unokuseta kwakhona i-MCB, i-fuse inokubona ezi meko, kwaye umsebenzisi kufuneka ayitshintshe.
I-MCB sisixhobo sombane esikhusela iingcingo zombane kunye nemithwalo kwi-inrush current, ukuthintela imililo kunye nezinye iingozi zombane.I-MCB ikhuselekile ukuphatha, kwaye ifumana amandla ngokukhawuleza.Ukulayisha ngaphezulu kunye nokukhuselwa kwesekethe okwethutyana kwizicelo zokuhlala, i-MCB lolona khetho ludumileyo.Ii-MCBs zikhawuleza kakhulu ukuseta ngokutsha kwaye azifuni kugcinwa.Ingcamango ye-bi-metal complementary isetyenziswa kwii-MCBs ukukhusela ngokuchasene nokuphuphumayo kwangoku kunye nesekethe emfutshane yangoku.
