MCCB yog dab tsi?
MCCB yog luv rau Moulded Case Circuit Breaker. Thaum tag nrho cov tam sim no tshaj qhov txwv ntawm lub thawv fuse micro, tus neeg siv siv nws ua lwm hom khoom siv tiv thaiv overcurrent. MCCB tiv thaiv los ntawm overvoltages nrog rau qhov txhaum tam sim no ua tsis tiav, nrog rau kev hloov pauv ntawm cov circuits.
Cov neeg siv khoom siv tau txawm tias nyob rau hauv tsev neeg siv rau cov ntsuas tam sim no zoo dua thiab cov qib ua yuam kev tshwm sim. Cov neeg siv siv MCCBs hauv cov txheej txheem lag luam vim lawv qhov nruab nrab ntawm cov ntsuas thiab muaj peev xwm tawg siab. MCCBs kuj tseem tuaj yeem tiv thaiv cov txhab nyiaj capacitor, cov generators, thiab kev faib cov khoom noj hluav taws xob tseem ceeb. Thaum ib daim ntawv thov xav tau kev coj ua tsis ncaj ncees, kev teeb tsa overloading customizable, lossis kev ruaj ntseg hauv av-qhov txhaum, nws muab kev tiv thaiv tsim nyog. Kev tau txais kev txaus siab ntawm cov neeg siv khoom yog peb lub tuam txhab lub hom phiaj mus ib txhis. Peb yuav ua qhov kev rau siab los tsim cov khoom tshiab thiab zoo tshaj plaws, ua tau raws li koj cov kev xav tau tshwj xeeb thiab muab rau koj cov kev pabcuam ua ntej muag, muag thiab tom qab muag rau kev txo nqi loj High Breaking Capacity Magnetic Moulded Case MCCB Circuit Breaker, Peb ntseeg tias peb yuav dhau los ua tus thawj coj hauv kev tsim thiab tsim cov khoom lag luam zoo tshaj plaws hauv ob lub khw Suav thiab thoob ntiaj teb. Peb vam tias yuav koom tes nrog ntau tus phooj ywg zoo rau kev sib koom siab.
