Daim ntawv thov

W7NL residual curretn breaker overload feem ntau yog siv rau AC 50Hz / 60Hz Circuit Court ntsuas 240V thiab 32A lossis qis dua. Lawv muaj lub electric to (hluav taws xob shock), overload, luv luv Circuit Court thiab thiaj li nyob rau hauv kev tiv thaiv muaj nuj nqi. Cov kev tiv thaiv dhau voltage kuj tuaj yeem muab tau raws li qhov yuav tsum tau ua. Lawv tsuas yog siv los tiv thaiv lub tsev teeb pom kev zoo thiab lub zog faib hluav taws xob.

Cov xwm txheej ua haujlwm li qub

■ Ambient cua kub: ambient cua kub reanges daim ntawv-5C ~ + 40C, tsis tshaj 35C qhov nruab nrab hauv 24 teev;

■ Qhov chaw: qhov chaw teeb tsa tsis tuaj yeem siab tshaj 2000 meters saum hiav txwv;

■ Huab cua tej yam kev mob: txheeb ze av noo nyob rau hauv qhov chaw installation tsis tuaj yeem ua tiav 50% thaum huab cua nce mus txog qhov kub siab tshaj +40C, qhov nruab nrab qhov nruab nrab qis thaum nws ntub dej tsis tshaj 25C, txheeb ze av noo tsis tshaj 90%;

■ Kev teeb tsa: kev teeb tsa tau faib ua qib II, qib I;

■Installationpollution gnage:installationpollution grade yog qib i;

■Installationconditions.magnetic teb sab nraum qhov chaw instation yuav tsis pub tshaj 5 zaug ntawm lub site ntawm terrestrial magnetism nyob rau hauv tag nrho cov kev taw qhia. Nquag hais lus, RCBO yuav tsum tau mounted vertically.lub lag luam kov tso los ntawm lub hwj chim qhov chaw nce, yuav tsum tsis muaj qhov tseem ceeb cuam tshuam thiab kev co nyob rau hauv qhov chaw installatin.

Daim ntawv ceeb toom

■ Kev tiv thaiv kev ua haujlwm ntawm RCBO raug kuaj thiab kho los ntawm kev tsim khoom, cov neeg siv tsis tuaj yeem qhib cov khoom ntawm random thaum siv;

■Tom qab siv RCBO rau ib lub sijhawm (feem ntau ib hlis), lub pob xeem yuav tsum tau nias ib zaug hauv lub xeev ntawm kev ua lub voj voog los xyuas seb qhov fuction ntawm RCBO puas zoo li qub thiab txhim khu kev qha (nias lub pob kuaj ib zaug, RCBO tuaj yeem tawg ib zaug). Yog tias txawv txav, nws yuav tsum tau muab tshem tawm thiab xa mus rau qhov chaw tsim khoom rau rpair.

■RCBO yuav tsum tsis txhob ntub los yog ntub los ntawm nag, daus los yog dej thaum lub caij tsheb thauj mus los, stroage thiab kev siv.
