Lub txee network nplhaib tau sib sau ua ke nrog 8MF profile, thiab lub qhov modulus E = 20mm tau teeb tsa rau ntawm tag nrho tus ncej. FZN21-12D hom load switch lossis FZRN21-12D hom fuse combination electrical applianceis nruab rau hauv lub txee network nplhaib. Hom khoom siv hluav taws xob no muaj disconnecting switch vacuum load switch, grounding ib nrab-qhib, thiab ob qho tib si disconnecting switch thiab grounding switch muaj qhov tawg pom tseeb.
Lub qhov hloov cais, lub qhov hloov nqus tsev, lub qhov hloov av thiab lub qhov rooj txee muaj cov khoom siv sib txuas thiab cov khoom siv sib txuas zoo meej, uas tuaj yeem tiv thaiv kev ua haujlwm tsis zoo thiab xyuas kom muaj kev saib xyuas zoo.
Nws tuaj yeem ua haujlwm tes thiab hluav taws xob. Lub qhov rooj ntawm lub txee ntsuas thiab lub qhov rooj ntsuas tau muab nrog cov koob txuas ua ke.
