Txhais thiab lub npe ntawm cov khoom siv hluav taws xob tam sim no me me

Ib qho me me seem tam sim no Circuit Court breaker (MRCB) yog ib qho khoom siv hluav taws xob hluav taws xob uas siv hluav taws xob sib txuas ua ke, luv luv -circuit, thiab seem tiv thaiv tam sim no. Raws li tus qauv me me Circuit Court breaker (MCB), nws ntxiv ib qho seem ua haujlwm tam sim no (RCD) module. Thaum cov hluav taws xob xau tshwm sim hauv cov kab lossis cov khoom siv, thiab cov seem tam sim no ncav cuag tus nqi (piv txwv li, 30mA), nws tuaj yeem txiav tawm sai sai, tiv thaiv hluav taws xob thiab hluav taws xob hluav taws xob. Cov khoom no feem ntau yog DIN rail mounted thiab yog haum rau ib zaug -theem fais fab faib tshuab nrog AC 50Hz thiab ib tug rated voltage ntawm 230V thiab hauv qab no. Nws yog dav siv nyob rau hauv cov chaw nyob thiab kev lag luam uas siab - qib kev tiv thaiv kev nyab xeeb yog xav tau rau lub davhlau ya nyob twg circuits.

Cov hluav taws xob hluav taws xob tam sim no me me (feem ntau hu ua residual tam sim no hloov lossis RCBO) yog cov khoom siv tiv thaiv hluav taws xob uas ua ke nrog kev tiv thaiv overload, luv - tiv thaiv hluav taws xob (MCB muaj nuj nqi), thiab kev tiv thaiv tam sim no (RCD muaj nuj nqi). Nws yog tsuas yog siv nyob rau hauv qis-voltage fais fab faib tshuab nrog AC 50Hz, ib zaug -theem 230V lossis peb-theem 400V thiab hauv qab no.

Cua Circuit Court breakers (me me Circuit Court breakers, MCBs) tsuas yog overload thiab luv- tiv thaiv Circuit Court; residual tam sim no cov cuab yeej (RCDs) tsuas yog muaj kev tiv thaiv tam sim no; thaum me me qhov seem tam sim no Circuit Court breakers (RCBOs) ua ke ua haujlwm ntawm ob qho tib si, ua rau lawv cov khoom siv tiv thaiv sib xyaw.

Cov npe lwm cov npe muaj xws li qhov hloov pauv tam sim no, qhov seem tam sim no ua haujlwm Circuit Court breaker (RCBO), thiab qhov seem tiv thaiv tam sim no hloov.
