Cov yam ntxwv ntawmCov MCCB

Cov MCCBtau tsim los nrog ntau yam haujlwm uas pab tiv thaiv cov kab ke hluav taws xob kom muaj kev nyab xeeb thiab txhim khu kev qha. Qee qhov tseem ceeb ntawm MCCB suav nrog:

Muaj peev xwm tawg siab:Cov khoom siv hluav taws xob molded casemuaj peev xwm rhuav cov hluav taws xob mus txog ntau txhiab amperes, ua rau lawv zoo tagnrho rau cov ntawv thov muaj zog heev.
Lub tshuab ua kom sov thiab sib nqus: Cov khoom siv hluav taws xob uas muaj pwm siv lub tshuab ua kom sov thiab sib nqus los ntes thiab teb rau cov hluav taws xob ntau dhau thiab luv luv. Cov khoom siv ua kom sov thiab sib nqus teb rau cov hluav taws xob ntau dhau, thaum cov khoom siv ua kom sov thiab sib nqus teb rau cov hluav taws xob luv luv.
Kev Teeb Tsa Hloov Tau: MCCBs muaj kev teeb tsa hloov tau, uas tso cai rau lawv teeb tsa rau qib tsim nyog rau daim ntawv thov xav tau.
Ntau yam ntawm qhov loj ntawm lub thav duab: MCCBs muaj ntau yam qhov loj ntawm lub thav duab, uas tso cai rau lawv siv rau hauv ntau yam kev siv. Lub hauv paus ntsiab lus ua haujlwm ntawm molded case circuit breaker Lub hauv paus ntsiab lus ua haujlwm ntawm MCCB yog raws li lub tshuab thermal-magnetic tripping. Lub thermal trip element hnov qhov kub uas tsim los ntawm cov dej ntws ntawm tam sim no hauv lub voj voog thiab trips lub circuit breaker thaum tam sim no tshaj qhov ntsuas trip. Lub magnetic trip element hnov qhov magnetic field tsim los ntawm luv luv circuit hauv lub voj voog, tripping lub circuit breaker yuav luag tam sim ntawd. Cov qauv ntawm molded case circuit breaker
Lub MCCB muaj ib lub tsev yas molded uas muaj lub tshuab mus ncig, cov neeg sib cuag thiab cov khoom nqa tam sim no.
Cov kev sib cuag yog ua los ntawm cov khoom siv conductive heev xws li tooj liab, thaum lub tshuab mus ncig muaj cov kab bimetallic thiab lub kauj sib nqus.
