ATS Dual Power Switch

STQ2-63 63A 2P CB Class Auto Transfer Switch 110V/220V - Economical Single-Phase ATS for Home & RV

The STQ2-63-2P is a CB class automatic transfer switch for single-phase 110V or 220V AC systems up to 63A, designed as an economical civilian-grade backup power solution. Using a circuit breaker with mechanical interlock mechanism, it physically prevents both power sources from being connected simultaneously. When Normal Power (N/mains) fails, the unit automatically switches to the backup supply (generator or PV inverter) in approximately 2 seconds; a brief ~2s power outage occurs during transfer, which is acceptable for most residential and light-duty loads. Once mains is restored, the unit reverts to Normal Power priority automatically. With a maximum load capacity of approximately 6930W (鈮?.9kW) and support for both auto and manual switching modes, the STQ2-63-2P is a straightforward, cost-effective choice for home emergency backup, RV power systems, fire-protection panels, elevator circuits, and general backup power applications.
