Puas yog koj xav tau cov khoom zoo thiab ruaj khov Earth Leakage Circuit Breakers?CDADAmuaj cov kev daws teeb meem OEM customization. Raws li ib tug txhim khu kev qha chaw tsim tshuaj paus nrog peb tus kheej lub Hoobkas, peb muab 3-xyoo warranty rau peb cov khoom.
IbNtiaj teb Leakage Circuit Breaker (CBR), kuj hu uaLub ntiaj teb Leakage Circuit Breaker nrog Kev Tiv Thaiv Kev Tiv Thaiv Kev Tshaj Tawm (CBR) Raws li IEC 60947-2 Annex B, yog cov khoom siv tiv thaiv hluav taws xob qis uas ua keresidual tam sim no (lub ntiaj teb to) tiv thaiv nrogoverload thiab luv-circuit tiv thaiv nyob rau hauv ib qho molded case unit. Ua haujlwm ntawm qhov ntsuas voltages mus txog415V AC (50/60Hz) nrog kev ntsuas tam sim no los ntawm16A rau 800A, CBRs ua hauj lwm raws li kev tiv thaiv cov cuab yeej siv rau kev lag luam, kev lag luam, thiab cov ntawv thov tseem ceeb.
Tsis zoo li standaloneResidual Current Circuit Breakers (RCCBs)uas tsuas yog muab kev tiv thaiv hauv ntiaj teb, CBRs koom ua ke:
Thermal-magnetic los yog hluav taws xob overcurrent tiv thaiv (L-S-I nkhaus)
Residual tam sim no nrhiav tau (10mA txog 1000mA rhiab heev)
Luv-circuit breaking peev xwm mus 85kA
Kev sib koom ua ke no tshem tawm qhov xav tau ntawm kev sib cais MCB / RCCB kev sib txuas, txo qhov chaw teeb tsa thiab txhim kho kev sib koom ua ke kev ntseeg tau.
