1 / 6ATS Dual Power Switch
63A 3P Automatic Transfer Switch 110V/220V - PC Class 50ms Three-Phase ATS for Commercial Use
The ATS-W2R-3P is a PC class (load level) automatic transfer switch for three-phase systems without neutral (3L only), rated at 63A and supporting both 110V and 220V AC. All three line poles switch simultaneously in 50ms, providing complete source isolation and preventing backfeed between mains and the backup supply. When Source A (mains) fails, the unit instantly transfers the load to a generator or PV inverter; once mains is restored, it automatically reverts to Source A priority without manual intervention. Supports both automatic and manual switching modes to suit different installation requirements. Built on a motor-driven mechanism housed in a PA6 flame-retardant enclosure, the W2R-3P is engineered for reliable continuous operation in demanding commercial environments 鈥?hospitals, cold-storage facilities, data centers, and industrial equipment requiring uninterrupted three-phase power.
