Tej yam me me Circuit Court breaker breaker (MCB) yog qhov kev nyab xeeb tseem ceeb tiv thaiv hluav taws xob overloads thiab luv voj voog. Txawm hais tias koj hloov kho koj lub tsev txoj phuam lossis ruaj khov chaw muaj kev lag luam, xaiv txoj caiMCB Homthiab ntaus kev ua kom muaj kev nyab xeeb thiab kev ua tau zoo. Tab sis nrog ntau txoj kev xaiv ntawm kev ua lag luam, koj txiav txim siab li cas? Cov lus qhia no rhuav tshem cov ntsiab lus tseem ceeb xws liMCB nqe, Hom (B / C / D), thiab hom kev ntseeg tau los pab koj ua kev yuav khoom.

Qhov tseem ceeb rau kev xav thaum yuav MCB

MCB hom: B, C, lossis D?

Hom B MCB: Qhov zoo tshaj plaws rau tsev (teeb pom kev zoo, cov ntsaws). Kev mus ncig ntawm 3-5x ntaus nqi tam sim no.

Hom C MCB: rau cov khoom siv nrog cov khoom hauv siab dua (ACS, cov tub yees). Mus ncig ntawm 5-10x.

Hom D MCB: Kev Siv Siv (Motors, Transformers). Mus ncig 10-20x.

Hwm hom: $ 25- $ 70 rau ib chav (industrial-kev ntseeg tau).

Qhov twg yuav MCBs: online vs. cov neeg muab khoom hauv zos

Cov khw muag khoom online (Amazon, eBay): Xaiv dav, kev sib piv ntawm McB, tab sis txheeb xyuas cov ntawv pov thawj.

Cov khw hluav taws xob hluav taws xob hluav taws xob: tau txais cov lus qhia los ntawm kev ua haujlwm, tab sis tus nqi yuav siab dua.

Ncaj nraim los ntawm cov tuam ntxhab: Hom nyiam CNC muab cov nyiaj txo thiab cov kev daws teeb meem.

Cov Lus Nug Hais Txog Kev Yuav Tej Me Me Circuit Court

Q1: Kuv puas tuaj yeem siv cov ntawv McB rau cov khoom siv lag luam?

Tsis tau. Muaj MCBs (hom D) muaj peev xwm sib tsoo ntau dua.

Q2: Ntev npaum li cas Mcbs ntev?

Zoo MCBS zoo li CNC xeem kawg 10-15 xyoo nrog kev txij nkawm kom tsim nyog.

Q3: Puas yog CNC MCBs tau tshaj cov ntoo qub? *

Yog lawm. CNC Tsim Kev Tiv Thaiv kom haum rau cov khoom siv hluav taws xob feem ntau.

Txawm hais tias koj xav tau hom B MCB rau koj lub tsev lossis lub luag haujlwm muaj kev ntsuas McB, ntsuas tus nqi sib npaug, qhov zoo, thiab kev nyab xeeb yog qhov tseem ceeb. Cov hom xws li Schneider Excel hauv Niche lag luam, tab sis CNC muaj ntau yam, muaj ntau yam kev daws teeb meem ntawm cov nqi MCB tsis muaj peev xwm.
