Switching in case of main power failure: When the main power supply (such as mains power) is cut off, the voltage is abnormal (too high/too low), or the frequency is unstable, ATS automatically detects and switches to the backup power supply (such as generator, battery, etc.).
More Details
The ATS constantly monitors the voltage, frequency, and stability of the primary power source (e.g., utility grid).If the primary power fails (outage, voltage sag/surge, or phase loss), the ATS triggers the transfer process.

An Air Circuit Breaker (ACB) is a type of circuit breaker that uses air as the arc extinguishing medium to protect electrical circuits from overloads, short circuits, and faults. ACBs are widely used in low-voltage (LV) and medium-voltage (MV) power distribution systems due to their high breaking capacity, reliability, and ease of maintenance.
