OVERVIEW
ATDH series bypass isolation automatic transfer switch, rated 400-4000 A, 415V and below, 50/60Hz. Bypass architecture serves as backup to the primary (main) ATS circuit, allowing maintenance of the main switch without interrupting load supply. Withdrawable mounting, Type H high short-circuit withstand only, Controller type A (in-phase transfer) or B (parallel transfer).
ATDH Bypass Isolation ATS menyediakan sirkuit bypass sebagai cadangan dari sirkuit utama (main circuit) untuk menjaga suplai daya ke beban tetap berjalan saat main switch dalam perawatan. Satu cabinet berisi main circuit ATS dan bypass circuit ATS (masing-masing withdrawable), dengan mekanisme cable interlock yang mencegah kedua sirkuit menutup bersamaan pada kutub yang sama.
KEY BENEFIT
Perawatan main switch tanpa memutus suplai ke beban; interlock mekanis mencegah kesalahan operasi; kontroler LCD 4.3 inci dengan indikator unlock terpisah untuk main dan bypass switch; kompatibel sistem utility-utility, utility-generator, dan generator-generator.
