About This

Reliable Dual Power Switching: The Automatic Transfer Switch 2P 63A is engineered for stable and continuous power supply. It automatically detects voltage loss and switches between main and backup sources in just 0.05 seconds, ensuring smooth transition without interruptions. Whether connected to city grid or generator/inverter, this ATS guarantees your appliances run safely and efficiently. Ideal for home, office, or industrial use, maintaining constant operation even during sudden outages.
Comprehensive Over-Voltage & Under-Voltage Protection: Equipped with smart voltage monitoring, the 63a ATS protects circuits from power anomalies. It operates at AC 110V 50/60Hz and supports current from 6A to 63A. The built-in undervoltage threshold (85V recovery 95V) and overvoltage threshold (145V recovery 130V ±5V) ensure your sensitive devices remain safe. Designed for long-term reliability, this feature makes it suitable for residential, commercial, and off-grid energy systems where voltage stability is critical.
Safe, Compact & Durable Construction: Crafted from high-quality flame-retardant PA6 material and pure copper conductive parts, this ATS transfer switch offers excellent durability, electrical safety, and heat resistance. Its compact DIN-rail mounting design fits perfectly into PZ30 distribution boxes, allowing neat installation and easy maintenance. Every connection terminal is clearly labeled for secure wiring, minimizing installation errors and improving operational safety. Built to last even under frequent switching conditions.
Automatic Mode: When using automatic mode, make sure the left switch is set to AUTO and the right handle is positioned at Ⅰ. When the main power supply (Ⅰ) is normal, the Ⅰ indicator (green light) stays ON. If the main power supply (Ⅰ) fails, the green light turns off, and within 0.05 seconds, the unit automatically switches to the backup power supply (Ⅱ) — the Ⅱ indicator (red light) will turn ON. Once the main power (Ⅰ) recovers, it automatically switches back from Ⅱ to Ⅰ to restore normal supply.
Manual Mode: For manual operation, set the left switch to MANU. If you want to use main power (Ⅰ), move the right handle to Ⅰ — the green light will turn ON to show the main supply is active. If you choose backup power (Ⅱ), move the handle to Ⅱ — the red light will turn ON, indicating the load is running on generator power.
Wide Applications & Reliable After-Sales Service: This 2P 63A automatic transfer switch is suitable for various dual power systems—city power with generator, inverter, or solar supply. It’s widely used in homes, RVs, offices, data centers, refrigeration units, hospitals, and emergency systems where uninterrupted power is vital. During main power loss, the ATS automatically engages the backup source, ensuring continuous operation. We offer a 30-day return and 3-year warranty, plus responsive technical support for installation and use.
