Nema 4X yog cov nruj kev tiv thaiv cov qauv txhais tau los ntawm cov hluav taws xob tsim hluav taws xob (NEMA) rau cov hluav taws xob hluav taws xob, feem ntau tsim los kom muaj kev ruaj khov nyob hauv ib puag ncig thiab sab nraum zoov. Nws yog dav pom tau rau nws txoj kev tsom mus rauMeich resilienceThiabIb puag ncig tsis kam, Ua rau nws cov qauv ua rau cov khoom siv tau ua rau ya raws, xeb, thiab kev ntxhov siab lub cev.
Cov ntawv pov thawj ua raws li kev sim ua kom nruj, suav nrog kev tiv thaiv dej (thooj zoo ib yam li IP66 \/ IP67), plua plav ingress, thiab cuam tshuam. Ib qho tseem ceeb sib txawv nyob hauv nwsCorrosion Kuj, Tiav los ntawm cov ntaub ntawv xws li stainless hlau (304\/316 qib), galvanized steel nrog tiv thaiv tiv thaiv, lossis cov ua haujlwm siab polymers. Cov ntaub ntawv no tiv tshuaj tsuag cov tshuaj nplaum, cov av noo, thiab tshuaj lom neeg raug mob, cov roj av & roj, thiab ua haujlwm siv tshuaj lom neeg.
Nema 4 x ntim khoom tseem hais txog cov kev tswj hwm kev tswj hwm, tso cai ua haujlwm kom ruaj ntseg thoob plaws. Tsis zoo li qis dua-Tier Nema kev ntsuas, nws yuav tsum tau seamless sealing ntawm gaskets lossis welded pob qij txha tiv thaiv kev toast, ua kom muaj kev cia siab ntev.
Thoob ntiaj teb, NEMA 4X feem ntau sib haum nrog IEC 60529 (tus lej IP) tab sis txuas ntxiv dhau ntawm kev tiv thaiv kev tiv thaiv kev sib xyaw ua ke. Nws qhov kev saws me me rau kev lag luam ua ntej kev nyab xeeb ua ntej kev nyab xeeb thiab ua raws li nws txhim kho cov khoom siv sia thiab txo tus nqi txij nkawm. Cov khoom lag luam ua lag luam kev lag luam thoob ntiaj teb feem ntau khub Nema 4X nrog UL lossis cov ntawv pov thawj kom tau ntsib ntau yam kev xav tau.
Hauv cov ntsiab lus, NEMA 4 daim ntawv pov thawj siv tau yog qhov ua kom haum rau cov kev mob siab, ua haujlwm raws li lub cim zoo thiab ua haujlwm hauv kev ua haujlwm tseem ceeb.
