FAQ
Common questions about LY1-C40PV/2(S) 1000V two-pole pluggable Type 1+2 DC surge protective device selection and installation.
Apa itu LY1-C40PV/2(S) 1000V digunakan untuk?
Ini dirancang untuk melindungi sistem fotovoltaik dan sistem listrik DC 1000V dari lonjakan yang disebabkan oleh petir dan overvoltage transien yang dihasilkan oleh saklar. Lokasi yang umum termasuk kotak penggabung PV, input DC inverter, dan kabinet distribusi DC.
Apakah ini adalah SPD DC Tipe 1+2?
Yes. The product is classified as Class I+II / Type 1+2 and lists both an 8/20μs discharge-current rating and a 10/350μs impulse-current rating.
Apa rating arus pengeluaran yang disediakan?
Ini menyediakan arus pelepasan nominal 20kA In, arus pelepasan maksimum 40kA Imax, dan arus pelepasan impuls terdaftar 6.25kA Iimp.
Apa yang dilindungi oleh konfigurasi dua kutub?
Konfigurasi dua kutub menyediakan jalur perlindungan lonjakan terpisah untuk konduktor DC positif dan negatif relatif terhadap tanah pelindung.
Bisakah kartrid perlindungan diganti?
Yes. The pluggable design allows individual protection cartridges to be inspected or replaced without removing the permanently wired base.
Apa yang harus dikonfirmasi sebelum memesan?
Confirm the maximum PV system voltage, 1000V DC operating requirement, DC+ and DC− protection arrangement, required Up level, backup-fuse coordination, conductor size, DIN-rail space, and remote-contact requirement.
