Lub luag haujlwm tseem ceeb ntawm JCR2-125 Residual Current Devices (RCDs) hauv Elec

It yog vim li no tias hluav taws xob kev nyab xeeb muaj rau feem ntau dhau los ua tus thawj tsav tsheb hauv lub ntiaj teb kev hloov pauv ntawm thev naus laus zis. Cov hluav taws xob hluav taws xob tuaj yeem muaj txiaj ntsig zoo rau ntau lub hom phiaj hauv zej zog tab sis tom qab ntawd lawv rov qab los nrog ntau yam kev phom sij uas yuav pom tau yog tias lawv tsis zoo nrog. Qhov no yog lub luag hauj lwm uas yog ua los ntawm covResidual Current Devices (RCDs)thiab Residual Current Circuit Breakers (RCCBs). Cov no yog npaj los tiv thaiv tib neeg thiab cov khoom muaj nqis los ntawm hluav taws xob txaus ntshai los ntawm kev txiav tawm lub voj voog sai sai thaum muaj qhov tsis zoo los yog cov dej xau tam sim no. Ib qho piv txwv ntawm xws li ib tug ntaus ntawv yog lubJCR2-125 RCD, uas tau tsim lub hom phiaj thiab tsim kho kom txo tau qhov yuav tau txais hluav taws xob poob qis thiab txo qhov kev pheej hmoo cuam tshuam nrog hluav taws xob hluav taws xob.

To taub cov JCR2-125 RCD

JCR2-125 RCD yog ib qho khoom siv hluav taws xob uas muaj kev txawj ntse heev vim nws txoj haujlwm tseem ceeb yog saib xyuas cov dej ntws los tiv thaiv cov neeg siv. Yog tias muaj qhov xau tam sim no nws txhais tau hais tias qee qhov ntawm qhov ntsuas tam sim no ua rau tam sim no los ntawm txoj kev tsis xav tau xws li los ntawm lub cev lossis kev puas tsuaj ntawm cov rwb thaiv tsev. JCR2-125 yog tsim tshwj xeeb los tawm hauv Circuit Court hauv qhov xwm txheej xws li kev tiv thaiv los ntawm kev raug mob lossis kev puas tsuaj.

Cov yam ntxwv tseem ceeb ntawm JCR2-125 RCD Circuit Court breaker tshiab tau piav qhia hauv qab no:
