C40 RCBO B Hom 40A 30mA RCD MCB C40 Hom B 40Amp Circuit Court Breaker

MCB,RCBO& RCCB:
• 10/15kA Miniature Circuit Breakers hauv B, C thiab D hom mus txog 63A
• 125A High tam sim no Miniature Circuit Court breaker hauv 3-ncej C Hom
• Ntau yam khoom siv muaj rau K Series MCBs suav nrog;shunt mus txawv tebchaws, dolly locks thiab auxiliary keyboards.
• 10kA Ob chav module SP&SwNRCBOs mus txog 40A / 30mA
• 10kA Ib-module RCBOs mus txog 45A / 30mA thiab 40A / 100mA
• RCCBs muaj nyob rau hauv 2-ncej thiab 4-ncej versions nrog 100A / 100mA Lub Sijhawm ncua sijhawm

Lub ntsiab parameter ntawm cov khoom seem tam sim no yog ntsuas qhov seem ua haujlwm tam sim no IΔn .Cov txiaj ntsig zoo li qub yog 10, 30, 100, 300, 500 mA thiab 1 A. Yog tias qhov seem tam sim no ua tiav tus nqi ntawm 100 % IΔn lossis ntau dua, RCD yuav tsum mus.Yog tias qhov seem tam sim no tsis ncav cuag 50% IΔn, nws yuav tsum tsis mus.Yog li, RCD tuaj yeem mus los ntawm 50 txog 100% IΔn .Qhov no txhais tau hais tias, muab qhov rhiab heev ntawm RCD ntawm 30 mA, tripping tuaj yeem tshwm sim sai li sai tau thaum lub ntiaj teb - qhov hluav taws xob tam sim no ntawm 15 mA tiav, uas ua rau muaj teeb meem hauv kev teeb tsa nrog cov xaim hluav taws xob ntau dua.Qhov no ua rau kom lawv siv tau rau hauv circuits nrog cov dej xau ntau dua.

Kev tiv thaiv ntawm RCCB tiv thaiv kev sib cuag overloading Kev tiv thaiv kev tiv thaiv ntawm kev sib cuag los ntawm cov hluav taws xob tam sim no txhais tau hais tias tsis tu ncua dhau tam sim no yuav tsis tshaj tus nqi ntawm lawv cov ntsuas tam sim no, uas lawv tau tsim.
