1P + N, RCBO, B, C nkhaus, ETM2RF, Residual Current Breaker nrog Over-Tam sim no tiv thaiv, ntsaws rau hauv
Khoom Description
ETM2RF series RCBO muaj feem xyuam rau cov hluav taws xob hluav taws xob hluav taws xob tsawg hauv kev lag luam, pej xeem lub tsev xws li lub tsev thiab qhov chaw nyob, lub zog, kev sib txuas lus, infrastructure, teeb pom kev zoo tis system los yog lub cev muaj zog faib thiab lwm yam.Lawv muab kev tiv thaiv to, tiv thaiv luv luv, tiv thaiv overload, thiab kev tiv thaiv kev sib cais, uas tuaj yeem tiv thaiv tib neeg los ntawm kev raug mob los ntawm kev xau ntawm tam sim no, ntawm qhov tseem ceeb thaum lawv tuaj yeem tiv thaiv Circuit Court thiab cov khoom siv los ntawm kev sib tsoo thib ob los ntawm kev sib tsoo thiab luv luv. Circuit Court.
ETM2RF series RCBO tau ua raws li IEC 61009-1 tus qauv.
Lub peev xwm tawg ntawm ETM2RF yog 10KA, lossis 6KA
Lub tripping yam luv luv Circuit Court yog B, C nkhaus.
Qhov ntsuas tam sim no yog 6A, 10A, 16A, 20A, 25A, 32A, 40A.Qhov ntsuas tam sim no muaj feem xyuam rau thaj chaw sib txawv siv piv txwv li ib tus ncej 10 mus rau 16 ampere feem ntau yog siv rau kev teeb pom kev zoo, 20 ampere mus rau 33 ampere feem ntau yog siv rau chav ua noj thiab chav dej hauv cheeb tsam, kuj siv rau cov cua txias thiab lwm yam khoom siv.
Lub rhiab heev tam sim no ntawm Residual Current, lossis Earth Leakage tripping yog 10mA, 30mA, 100mA, thaum 10mA thiab 30mA feem ntau yog siv hauv Circuit Court ntawm chav da dej thiab chav ua noj los tiv thaiv tib neeg los ntawm hluav taws xob poob siab.
Hom tripping ntawm Residual tam sim no yog AC lossis A chav kawm.AC chav kawm Tripping yog ua kom paub tseeb rau sinusoidal, alternating tam sim no, txawm tias lawv yuav tsum tau ceev ceev los yog maj mam nce.Ib chav kawm Tripping yog ua kom paub tseeb rau sinusoidal, alternating residual tam sim no nrog rau cov pulsed DC residual tam sim no, txawm tias lawv yuav tsum tau ceev ceev los yog maj mam nce.
Rated voltage: 230V / 240V (phase & nruab nrab)
Muaj ib txoj hauj lwm qhia nruab rau ntawm cov khoom, Liab yog nyob rau, Ntsuab yog tawm.
Lub RCBO terminals yog IP20 kev tiv thaiv uas yog tsim los rau cov ntiv tes thiab tes kov kom muaj kev nyab xeeb thaum nruab.
ETM2RF RCBO tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig hnyav, hauv qhov kub thiab txias ntawm -25 ° C txog 55 ° C.
Lub neej hluav taws xob tuaj yeem ncav cuag 8000 kev ua haujlwm thiab lub neej txhua yam mus txog 20000 kev ua haujlwm, thaum qhov kev xav tau ntawm IEC tsuas yog 4000 kev ua haujlwm thiab 10000 kev ua haujlwm.
Lub mounting hom ntawm cov terminals yog ntsaws rau hauv hom nyob rau hauv lub tswv yim sab, thiab thaiv hom ntawm cov zis sab.
RCBO yog dab tsi?
RCBO sawv cev rau Residual Current Breaker nrog kev tiv thaiv dhau tam sim no.Lub RCBO sib txuas ua haujlwm ntawm MCB thiab RCD / RCCB.Thaum muaj qhov xau tam sim no, RCBO mus ncig tag nrho lub voj voog.Yog li ntawd, cov khoom siv hluav taws xob sib nqus / thermal Circuit Court breaker tuaj yeem mus rau cov khoom siv hluav taws xob thaum lub Circuit Court overloaded.
1. Cov Hluav Taws Xob Hluav Taws Xob, lossis Lub Ntiaj Teb Leakage - tshwm sim thaum muaj kev sib tsoo hauv Circuit Court los ntawm cov hluav taws xob tsis zoo lossis DIY xwm txheej xws li drilling los ntawm cable thaum mounting daim duab nuv los yog txiav los ntawm cable nrog cov nyom mower.Hauv qhov xwm txheej no, hluav taws xob yuav tsum mus rau qhov chaw thiab xaiv txoj kev yooj yim tshaj plaws taug kev los ntawm lub tshuab txiav nyom lossis laum rau tib neeg ua rau hluav taws xob poob.
2. Tshaj-Tam sim no siv ob hom:
ib.Overload - tshwm sim thaum muaj ntau yam khoom siv nyob rau hauv lub voj voog, kos ib tug npaum li cas ntawm lub hwj chim uas tshaj lub peev xwm ntawm lub cable.
b.Short Circuit - tshwm sim thaum muaj kev sib txuas ncaj qha ntawm cov neeg nyob thiab nruab nrab.Yog tias tsis muaj qhov tsis kam muab los ntawm kev ua haujlwm ntawm lub cev ib txwm muaj, cov hluav taws xob tam sim no rushes nyob ib ncig ntawm lub voj voog hauv ib lub voj voog thiab muab cov amperage ntau txhiab zaus hauv milliseconds xwb thiab yog qhov txaus ntshai ntau dua li Overload.
Thaum RCCB tsuas yog tsim los tiv thaiv lub ntiaj teb to thiab MCB tsuas yog tiv thaiv dhau tam sim no, RCBO tiv thaiv ob hom kev txhaum.
