## Long description

APC Automatic Transfer Switch AP7721-RFB is a 230V 16A two-input ATS that automatically switches power between two AC sources, for example mains and generator. Designed for reliable and fast transfer, the AP7721-RFB maintains continuity of power to connected equipment and reduces downtime for small servers, telecommunications gear and critical appliances. The unit is compact and intended for straightforward installation where automatic source switching is required for backup power continuity.
Advantages
The AP7721-RFB provides automatic, seamless switching between two power sources at 230V and up to 16A, minimising manual intervention during a mains failure. Its two-input configuration supports a primary and a backup source such as utility power and a generator. The device is engineered to deliver fast transfer timing to help keep sensitive equipment operational and to protect against prolonged power interruptions. The product is manufactured by APC and carries the model identifier AP7721-RFB (MPN: AP7721-RFB, EAN: 5711783909910).

How to use
Install the AP7721-RFB in accordance with local electrical codes and the manufacturer’s installation instructions. Connect the primary AC source (mains) to the designated input and the backup source (generator) to the secondary input. Connect the load output to the equipment requiring protected power. Verify wiring, ground connections and rated current compatibility before energising. On loss of the primary source, the switch will transfer load automatically to the backup source; when the primary source returns, it will transfer back according to the product’s transfer logic. Commission the unit by testing transfer behaviour under controlled conditions to ensure correct operation with the intended load.
Usage recommendations
The AP7721-RFB should be used with appropriate overcurrent protection and installed by a qualified electrician. Ensure the connected load does not exceed 16A at 230V and confirm generator voltage and frequency compatibility before use. Periodic testing and inspection are recommended to verify transfer performance and connection integrity.
