Cov Lus Qhia Xaiv DIN Rail Terminal Block: Cov Kev Ntsuas Tam Sim No, Cov Khoom Siv, thiab Cov Qauv Mounting
TL;DR
- Xaiv cov thaiv davhlau ya nyob twg DIN rail los ntawm kev sib phim qhov tam sim no ntsuas (24A txog 232A) rau koj lub voj voog thauj khoom, nrog rau qhov seem ntawm tus neeg coj ua qhov kev txwv lub cev tseem ceeb.
- PA66 nrog V-0 qhov ntsuas kev kub hnyiab yog cov khoom siv zoo tshaj plaws rau cov txee tswj kev lag luam, ua haujlwm tau zoo ntawm -40C txog + 120C.
- TS35 (35x7.5mm) ib qho EN 60715 yog tus qauv mounting profile; xyuas seb hom tsheb ciav hlau thiab cov khoom siv tuab (1.0 ± 0.1mm) ua ntej xaj.
- UL 1059 rau North America thiab CE/IEC 60947-7-1 rau EU kev ua lag luam yog cov ntawv pov thawj tsawg kawg nkaus uas koj lub davhlau ya nyob twg yuav tsum muaj.
- Cov hom caij nplooj ntoos hlav-clamp txo lub sijhawm teeb tsa los ntawm kwv yees li 40% piv rau cov blocks hom ntsia hlau, ua rau lawv tsim nyog rau cov vaj huam sib luag tswj hwm siab.
Xaiv lub DIN rail terminal block kom raug rau lub vaj huam sib luag tswj kev lag luam yuav tsum phim peb qhov kev ntsuas: qhov ntsuas tam sim no yuav tsum tshaj qhov siab tshaj plaws ntawm lub voj voog los ntawm tsawg kawg 20%, cov khoom siv hauv tsev yuav tsum tiv taus qhov chaw ua haujlwm, thiab cov qauv mounting yuav tsum ua raws li EN 60715 tus qauv. Phau ntawv qhia no piav qhia txog txhua yam lus qhia nrog cov ntaub ntawv ntsuas tau thiab cov ntawv sau tseg hauv lub ntiaj teb tiag.
Hauv ntau tshaj kaum xyoo ntawm kev tsim cov terminal blocks rau OEMs thoob plaws North America, Tebchaws Europe, thiab Southeast Asia, peb tau pom cov kev ua yuam kev xaiv tib yam rov ua dua - cov blocks loj dua rau cov teeb liab qis, cov rails me dua rau cov blocks ntau theem hnyav, thiab cov khoom siv tsis sib xws uas ua rau muaj kev ua tsis tiav hauv thaj teb. Phau ntawv qhia no muaj los tshem tawm cov kev ua yuam kev ntawd.
Cov Kev Ntsuas Tam Sim No rau DIN Rail Terminal Blocks yog dab tsi?
Cov ntsuas tam sim no ntawm DIN rail terminal block yog txij li 24A rau cov qauv 2.5mm2 pub-dhau mus txog 232A rau cov khoom siv hluav taws xob hnyav 95mm2, raws li tau teev tseg los ntawm IEC 60947-7-1 thiab UL 1059 cov qauv.
Txhua lub thaiv davhlau ya nyob twg muaj ob qhov ntsuas tam sim no: qhov ntsuas tam sim no ua haujlwm (Ie) raws li IEC 60947-7-1 thiab qhov ntsuas tam sim no UL. Lawv feem ntau - tab sis tsis yog txhua lub sijhawm - zoo ib yam. Qhov tam sim no tiag tiag uas lub thaiv tuaj yeem nqa tau nyob ntawm qhov hla ntawm tus neeg coj hluav taws xob, qhov kub thiab txias, thiab seb lub thaiv puas tau teeb tsa rau hauv ib txheej lossis teeb tsa ua pawg.
