FAQ
Common questions about LY1-C40/2(S) two-pole pluggable Type 2 AC surge protective device selection and installation.
Apa kegunaan LY1-C40/2(S)?
LY1-C40/2(S) digunakan untuk membatasi overvoltase transien dalam sistem distribusi AC tegangan rendah melalui dua jalur perlindungan. Ini cocok untuk panel distribusi, kabinet kontrol, sistem daya komersial, dan panel peralatan.
Apakah LY1-C40/2(S) adalah SPD satu kutub atau dua kutub?
LY1-C40/2(S) adalah SPD dua kutub. Judul halaman yang ada yang menyebutnya sebagai kutub tunggal harus diubah menjadi kutub dua.
Apakah produk ini merupakan SPD Tipe 2?
Yes. LY1-C40/2(S) is classified as a Class II / Type 2 AC surge protective device. The incorrect Type 1CA wording should not be used.
Apa rating arus pengeluaran yang disediakan?
The SPD provides 20kA nominal discharge current In and 40kA maximum discharge current Imax. The technical table also lists a 7kA impulse-current parameter.
Opsi tegangan apa yang tersedia?
Maximum continuous operating voltage options include 75V, 150V, 275V, 320V, 385V, and 440V AC. Select the appropriate version according to the nominal system voltage.
Apa yang harus dikonfirmasi sebelum memesan?
Confirm the nominal voltage, Uc and Up requirements, two-pole protection arrangement, 125A maximum backup-fuse coordination, conductor size, DIN-rail space, and optional remote-contact requirement.
