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).
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).
The ATDH Bypass Isolation ATS provides a bypass circuit as a backup to the main circuit to maintain power supply to the load while the main switch is undergoing maintenance. A single cabinet houses both the ATS main circuit and the ATS bypass circuit (each of which is withdrawable), with a cable interlock mechanism that prevents both circuits from closing simultaneously on the same pole.
KEY BENEFIT
Eaton ATDH Bypass Isolation ATS allows maintenance and inspection of the main transfer switch without interrupting the load supply through its dedicated bypass path. Its withdrawable design, cable interlock, and separate switch status indicators improve operational safety and serviceability. With 400–4,000 A capacity and flexible 3-pole, 4-pole, and 3N configurations, it is suitable for utility-to-utility, utility-to-generator, and generator-to-generator systems.
