2P 63A 220V Dual Power Automatic Transfer Switch ATS

ZLQ3-63-2 Dual Power Automatic Transfer Switch – 2P 63A 220V

Keep your home, office, or small industrial facility powered around the clock with the ZLQ3-63-2 Dual Power Automatic Transfer Switch (ATS). Rated at 63A and 220V AC (50/60Hz), this 2-pole miniature circuit breaker-style switch automatically transfers your load to a backup power source within milliseconds whenever the main supply is interrupted — all without manual intervention. It also supports full manual changeover mode for added flexibility during maintenance or testing.

Key Features

• Flame-Retardant Housing: Constructed from high-grade flame-retardant PC material that withstands high temperatures and significantly reduces fire risk caused by overcurrent conditions, extending the product's service life.
• Overload & Short-Circuit Protection: High-precision internal copper conductors paired with a built-in safety protection module automatically cut the circuit when an overload or short circuit is detected, keeping your connected appliances safe.
• Tool-Free 35mm DIN Rail Installation: Designed for standard 35mm electrical rails — simply snap it in place. No drilling required, and the unit is equally easy to remove for maintenance.
• Millisecond-Speed Automatic Transfer: The built-in high-sensitivity intelligent control module detects a primary supply failure and switches to the backup source in milliseconds, ensuring uninterrupted power 24/7. Manual switching is also supported.
• Thickened Cold-Rolled Steel Bracket: The anti-rust coated, cold-rolled steel mounting bracket provides firm, deformation-free fixation even in demanding or complex installation environments.
• LED Status Indicators: Independent LED indicator lights and clear operation labels let you instantly identify the current working mode and supply status, simplifying daily inspection and fault-finding.

Frequently Asked Questions

Q: What is a Dual Power Automatic Transfer Switch (ATS) and how does it work?

A: A Dual Power Automatic Transfer Switch (ATS) continuously monitors your main power supply. The moment a failure is detected, the built-in intelligent control module automatically switches the connected load to a backup power source — typically within milliseconds — without requiring any manual action. Once the main supply is restored, it can switch back automatically or manually, depending on the operating mode selected.

Q: Is the ZLQ3-63-2 compatible with standard DIN rail enclosures?

A: Yes. The ZLQ3-63-2 uses a standard 35mm DIN rail mounting design, making it compatible with most common electrical distribution boards and enclosure panels. No drilling or special tools are needed — simply clip it onto the rail and secure wiring to the clearly marked terminals.

Q: Can this transfer switch be operated manually as well as automatically?

A: Absolutely. While the primary function is fully automatic millisecond-speed power transfer, the switch also features a manual changeover mode. This is especially useful during planned maintenance, testing, or generator start-up sequences where you need direct control over the switching operation.

Q: What applications is this 2P 63A ATS suitable for?

A: This switch is well-suited for residential, commercial, and small industrial applications requiring reliable uninterrupted power supply. Typical uses include backup generator integration, UPS systems, and any setup where continuous power to critical equipment — such as security systems, lighting, or machinery — is essential.
