Comprehensive 3-Phase Protection: Provides robust, simultaneous protection for all three phases against severe voltage faults, including **Over-Voltage, Under-Voltage, Phase Loss (Single Phasing), and Phase Sequence (Reverse Phase)** errors. Automatic Disconnection: Instantly and automatically **disconnects the load** when any voltage anomaly is detected across any of the phases, preventing damage to connected 3-phase equipment. Adjustable Response and Delay Time: Allows the user to set **customizable parameters** for the voltage trip limits and an adjustable **reconnection delay time** to prevent short-cycle damage to machinery (e.g., HVAC units). High Current Capacity: Available in various current ratings (e.g., $40\text{A}, 63\text{A}, 100\text{A}$), suitable for the main protection of industrial machinery, large commercial buildings, and critical infrastructure. (Specify actual rating if known.) Digital Fault Display: Equipped with an **LED or LCD digital display** to show real-time voltage readings for all three phases and clearly indicate the cause of the latest trip (e.g., "Hi-V" or "Phase Loss"). Zero-Crossing Switching: Utilizes advanced technology (in high-end models) for switching near the zero-crossing point, which **minimizes electrical arcing** and extends the lifespan of the internal components. Automatic Reconnection: Once the power supply returns to acceptable limits for the specified duration, the AVS automatically and safely **restores power** to the connected load.
