1 / 6ATS Dual Power Switch
63A 4P Automatic Transfer Switch 110V/220V - PC Class 50ms Three-Phase ATS for Commercial Use
The ATS-ST-4P-63A is a PC class (load level) automatic transfer switch for three-phase systems with neutral (3L+N), rated at 63A and supporting both 110V and 220V AC. All four poles 鈥?three phases and neutral 鈥?switch simultaneously in 50ms, ensuring complete source isolation and preventing any backfeed between the two supplies. When mains power fails, the unit instantly transfers the load to the backup source (inverter or generator); once mains is restored, it automatically reverts to Source I priority. Built-in voltage monitoring provides over-voltage and under-voltage protection across both voltage settings: for 110V systems the thresholds are 85V鈥?45V, and for 220V systems 175V鈥?60V. The motor-driven switching mechanism enclosed in a PA6 flame-retardant housing ensures reliable and safe operation in demanding commercial environments such as hospitals, cold-storage facilities, and data centers.
