Power Automatic Transfer Switch SGQ163AE/4P, Size 110V Overview The SGQ163AE/4P automatic transfer switch provides fast, reliable switching between two power sources. Designed for AC systems operating at 50 to 60Hz, it automatically switches from primary power A to backup power B in the event of supply abnormality, restoring power in milliseconds and minimizing manual intervention. Key benefits Continuous power for critical loads: Automatic switching keeps essential equipment running when the main supply fails, reducing downtime and the need for manual transfer. Fast response: Millisecondlevel switching ensures rapid activation of the backup source to maintain service continuity. Durable construction: Flame retardant PC housing offers insulation, heat resistance, and aging resistance for longterm use. Improved conductivity and longevity: Silver touch points enhance electrical contact quality and extend service life. Simple integration: Designed for standard AC systems at 50 to 60Hz and suitable for installations that require a 110V control size.
