Yam ntxwv ntawmMCCBs

MCCBsyog tsim los nrog ntau lub zog uas pab tiv thaiv hluav taws xob hauv kev nyab xeeb thiab txhim khu kev qha.Qee qhov tseem ceeb ntawm MCCB suav nrog:

High breaking peev xwm:Moulded case Circuit Breakersmuaj peev xwm tawg tam sim no mus txog ntau txhiab amperes, ua rau lawv zoo tagnrho rau kev siv hluav taws xob siab.
Thermal-magnetic trip mechanism: Moulded case circuit breakers siv lub thermal-magnetic trip mechanism los ntes thiab teb rau overcurrent thiab luv circuits.Thermal trip elements teb rau overloads, thaum sib nqus cov ntsiab lus teb rau luv circuits.
Adjustable Trip Setting: MCCBs muaj qhov chaw taug kev tuaj yeem kho tau, uas tso cai rau lawv mus rau theem tsim nyog rau daim ntawv thov xav tau.
Ntau qhov ntau thiab tsawg ntawm cov ncej: MCCBs muaj nyob rau hauv ntau qhov ntau thiab tsawg, uas tso cai rau lawv siv ntau yam kev siv.Ua hauj lwm hauv paus ntsiab lus ntawm molded case circuit breaker Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm MCCB yog raws li lub thermal-magnetic tripping mechanism. .Lub thermal mus ncig lub caij hnov cov cua sov uas tsim los ntawm qhov ntws ntawm tam sim no hauv Circuit Court thiab mus ncig lub Circuit Court breaker thaum tam sim no tshaj qhov ntsuas kev mus ncig.Cov khoom sib nqus mus ncig ua rau pom qhov chaw sib nqus tsim los ntawm luv luv Circuit Court, tripping lub Circuit Court breaker yuav luag tam sim.Structure ntawm molded case Circuit Court breaker
MCCB muaj ib lub tsev yas molded uas yog lub tsev rau kev mus ncig, kev sib cuag thiab cov khoom nqa tam sim no.
Cov kev sib cuag yog tsim los ntawm cov khoom siv hluav taws xob zoo xws li tooj liab, thaum lub sijhawm mus ncig ua haujlwm muaj cov kab sib nqus bimetallic thiab cov hlau nplaum sib nqus.
