Economical Type 2 1+1 Architecture for Small TT/IT Unearthed Systems
Product Overview
NPS01-F20 AC 1+1P Surge Protective Device yog hom kev lag luam 2 (Class II) surge tiv thaiv ntaus ntawv tshwj xeeb tsim rau me me TT thiab IT unearthed power distribution systems. Nws ua tau raws li EN/IEC 61643-11 thiab GB/T 18802.11 tus qauv thiab tau dhau hom 2+3 ntawv pov thawj. Cov khoom lag luam nta ib qho 1+1 kev tiv thaiv kev sib txuas ua ke ntawm theem- kab varistor nrog qhov nruab nrab- kab mob siab rau qhov sib txawv, xa tawm tam sim nominal tawm hauv 10kA (8/20μs) thiab qhov siab tshaj tawm tam sim no Imax ntawm 20kA, nrog qhib qhov hluav taws xob ntawm 6kV. Qhov kev teeb tsa no muab kev ywj pheej L-PE thiab N-PE surge txoj kev tiv thaiv, zoo kawg nkaus phim cov kev xav tau ntawm cov tshuab me me uas tsis tau pom dua. Lub 36 hli ob-ncej dav haum tus qauv 35mm DIN rail mounting, nrog Uc npog 275V rau 440V (NPE hom 255V). Nws yog dav siv nyob rau hauv cov chaw kho mob me me, chaw ua haujlwm IT systems, thiab cov khw muag khoom soj ntsuam uas siv TT lossis IT earthing configurations.
Phase Varistor + N-PE Gap – Zero Leakage Tam Sim No rau Cov Me Me Unearthed Systems
Cov theem Circuit Court siv lub siab -zog zinc oxide varistor nti uas teb sai sai thiab tswj cov hluav taws xob uas tsis muaj zog, ua kom muaj zog tiv thaiv hluav taws xob. Qhov nruab nrab-rau- lub ntiaj teb Circuit Court siv lub tshuab hluav taws xob tso tawm tshwj xeeb, uas ua haujlwm nrog xoom xaim tam sim no thiab xoom hluav taws xob siv nyob rau hauv ib txwm muaj - daws cov teeb meem nruab nrab tsis sib haum thiab cuam tshuam cov teeb meem tshwm sim hauv TT / IT systems. Ob -theem tiv thaiv cov ntsiab lus yog lub zog muaj zog- sib koom ua ke, kom tsis txhob ua raws li tam sim no thiab tsis muaj qhov muag tsis pom ntawm theem. Txhua tus ncej yog nws tus kheej nruab nrog lub thermal disconnector thiab lub qhov rais liab / ntsuab qhov taw qhia. Ib leeg-ncej tsis ua haujlwm ua rau muaj kev sib cais tsis siv neeg yam tsis muaj kev cuam tshuam rau lwm tus ncej, ua qhov chaw txhaum sai thiab nkag siab. Lub busbar conductive yog ua los ntawm siab - purity tooj liab nrog tin plating, kom ntseeg tau tias tsis tshua muaj kev tiv thaiv thiab siab surge tam sim no muaj peev xwm. Lub vaj tsev yog ua los ntawm UL94V-0 cov khoom siv thermoplastic liab nrog kev tiv thaiv IP20.
40A Rov qab-Up Fuse - Tus Nqi -Kev daws teeb meem zoo rau cov tshuab me me
Cov koob no muaj kev tiv thaiv Up voltage tsawg li 0.9kV, nrog rau theem - hom teb lub sij hawm tsawg dua los yog sib npaug rau 25ns thiab N-PE hom teb lub sij hawm tsawg dua los yog sib npaug rau 100ns, sib txuas cov hluav taws xob qis nrog kev tiv thaiv siab. A 40A gG rov qab-up fuse raug pom zoo kom ua tiav kev xaiv kev sib koom tes zoo ntawm cov theem tiv thaiv sab saud thiab qis. Ib qho kev xaiv ib txwm qhib / ib txwm kaw ntab hloov pauv kev sib cuag rau cov chaw taws teeb ceeb toom (AC 250V / 0.5A) yog muaj rau kev saib xyuas yooj yim. Cov cuab yeej ua haujlwm nyob rau hauv -40℃rau +80℃thiab 5% mus rau 95% av noo, thiab haum rau conductors ntawm 4mm² txog 25mm². Nrog 35 hli DIN rail mounting ceev thiab ib tug compact 36mm dav, qhov no yog ib tug nqi-zoo tshuaj rau theem nrab surge tiv thaiv nyob rau hauv me me TT / IT unearthed tis systems.
