Cov ntsaws rau kev lag luamFeem ntau yog siv rau kev sib txuas hluav taws xob hauv cov chaw ua haujlwm, kom ua tiav kev sib txuas thiab rho tawm kev sib txuas ntawm cov khoom siv thiab cov chaw muab hluav taws xob kom ruaj khov, ruaj khov thiab sai. Lawv siv dav hauv cov xwm txheej xws li cov khoom siv hauv Hoobkas, kev tsim khoom siv, qhov chaw tsim kho, tshuab vuam, lub thawv faib khoom, nkoj thiab kev muab hluav taws xob ib ntus sab nraum zoov. Nws lub luag haujlwm tseem ceeb yog txhim kho kev nyab xeeb ntawm kev siv hluav taws xob thiab tiv thaiv cov ntsaws hluav taws xob ib txwm kom tsis txhob muaj kev sib cuag tsis zoo, luv luv lossis poob rau hauv qhov chaw muaj hluav taws xob siab, av noo, plua plav lossis co. Cov ntsaws hluav taws xob hauv kev lag luam feem ntau muaj kev tiv thaiv dej, tiv thaiv plua plav, tiv thaiv kub siab, thiab tiv thaiv kev cuam tshuam. Cov qib tiv thaiv feem ntau suav nrog IP44 thiab IP67.

Hais txog tus nqi, cov ntsaws hluav taws xob hauv kev lag luam sib txawv ntau nyob ntawm hom, khoom siv, qhov ntsuas tam sim no (16A / 32A / 63A / 125A), qib kev tiv thaiv, thiab seb lawv puas muaj qhov xauv lossis tsis muaj. Tus nqi ntawm cov ntsaws hluav taws xob hauv tsev 16A feem ntau yog li ntawm 10 txog 30 yuan. Cov lus qhia 32A yog kwv yees li ntawm 20 txog 60 yuan. Cov qauv hnyav ntawm 63A thiab siab dua tuaj yeem raug nqi 80 txog 300 yuan lossis ntau dua. Tus nqi ntawm cov hom lag luam xa tawm (xws li Schneider, ABB, thiab lwm yam) feem ntau yog 2 txog 5 npaug ntawm cov hauv tsev.

Zuag qhia tag nrho, kev xaiv cov ntsaws hluav taws xob rau kev lag luam yuav tsum yog raws li kev txiav txim siab dav dav ntawm qhov tam sim no siv, cov xwm txheej ib puag ncig thiab cov kev cai nyab xeeb, es tsis yog tsuas yog saib tus nqi.
