GCDQCN GCQ2‑63/2P ATS Automatic Transfer Switch 2P 63A AC230V Auto Manual Dual Power Changeover for Home Generator Emergency Backup Power

This is a CB‑grade 2‑pole automatic transfer switch (ATS). It is designed for single‑phase 230V systems, which automatically switches the load between primary power source and standby power source. When the main power fails, loses voltage or goes abnormal, the switch will transfer to standby power automatically; it will switch back to main power once mains supply restores. Manual operation is also available for maintenance purposes.
