Txhim kho hom 2 1+1 Architecture rau Demanding TT/IT Unearthed Systems
Product Overview
NPS01-F80 AC 1+1P Surge Protective Device yog ib qho kev txhim kho hom 2 (Class II) surge tiv thaiv ntaus ntawv tshwj xeeb tsim rau kev thov TT thiab IT unearthed power distribution systems. Nws ua raws li EN/IEC 61643-11 thiab GB/T 18802.11 tus qauv thiab tau dhau daim ntawv pov thawj Type 2. Cov khoom lag luam nta ib qho 1+1 kev tiv thaiv architecture sib txuas ua ke ib theem- kab siab- zog varistor nrog qhov nruab nrab- kab mob siab rau qhov sib txawv, xa tawm tam sim nominal tawm hauv 40kA (8/20μs) thiab qhov tso tawm siab tshaj plaws tam sim no Imax ntawm 80kA. Qhov kev teeb tsa no muab kev ywj pheej L-PE thiab N-PE surge txoj kev tiv thaiv nrog kev muaj peev xwm ua kom zoo dua qub, zoo sib xws rau cov kev xav tau ntawm cov kev faib tawm uas tsis tau pom dua nrog kev nthuav dav dua. Lub 72 hli ob-ncej dav haum tus qauv 35mm DIN rail mounting, nrog Uc npog 275V rau 440V (NPE hom 255V). Nws yog siv dav hauv cov chaw kho mob, kev tswj hwm kev lag luam, thiab cov chaw zov me nyuam cov ntaub ntawv uas siv TT lossis IT earthing configurations thiab yuav tsum tau ua kom muaj peev xwm tuav tau tam sim no.
Phase Varistor + N-PE Gap – Zero Leakage nrog Txhim Kho Kev Tiv Thaiv
Lub voj voog theem siv qhov loj - txoj kab uas hla siab - lub zog zinc oxide varistor nti uas teb sai sai thiab tswj xyuas qhov hluav taws xob tsis zoo, ua kom muaj zog tiv thaiv siab heev - hluav taws xob hluav taws xob ntau. Qhov nruab nrab-rau- lub ntiaj teb Circuit Court siv lub siab siab siab- muaj peev xwm roj tawm qhov sib txawv, uas ua haujlwm nrog xoom xaim tam sim no thiab xoom hluav taws xob siv nyob rau hauv ib txwm muaj - tshem tawm cov kab nruab nrab drift thiab kev 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 stamped los ntawm siab -purity T2 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.
125A Rov qab-Up Fuse - Kev daws teeb meem zoo rau kev thov cov tshuab tsis pom
Cov koob no muaj kev tiv thaiv Up voltage tsawg li 1.5kV, 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 uas tsis tshua muaj nrog kev tiv thaiv siab. A 125A gG rov qab- nce fuse yog pom zoo kom ua tiav kev xaiv kev sib koom ua ke ntawm kev tiv thaiv sab saud thiab qis qis. Ib qho kev xaiv ib txwm qhib / ib txwm kaw ntab hloov pauv kev sib cuag rau cov chaw taws teeb teeb liab (AC 250V / 0.5A) muaj, txhawb kev sib txuas rau kev tswj hwm lub tsev lossis kev saib xyuas rau cov chaw taws teeb saib xyuas. Cov cuab yeej ua haujlwm nyob rau hauv -40℃rau +80℃thiab 5% mus rau 95% av noo, thiab haum rau cov neeg xyuas pib ntawm 4mm² txog 35mm². Nrog 35 hli DIN rail mounting ceev, qhov no yog ib qho kev daws teeb meem rau kev tiv thaiv kev nce siab ntxiv hauv kev thov TT / IT unearthed tis systems.
