ATS/Automatic Transfer
Model meaning:
Designed as an AC power system, the MTQ3 ATS can accommodate 3P/4P configurations, various current levels and a broad voltage range, thus it can be used in the heavy-industrial, commercial and infrastructure-grade sectors. Its intelligent control logic combined with the mechanical interlocking structure and transfer performance reliability make it a perfect choice for power management in mission-critical situations.
The MTQ3 Automatic Transfer Switch is a device that guarantees, swiftly and fully automatic, the transfer of load execution between two independent power sources. The switch is equipped with a robust mechanical mechanism and advanced electrical control technology, thus providing power restoration in a short, but also safe, way in the case of a power outage. It is designed to work in both automatic and manual modes, thus providing an operation flexibility that depends on the system's requirements.
Constructed in compliance with IEC 60947-6 and quality controlled under ISO, CE, and RoHS certification systems, the MTQ3 ATS is a unit that assures stability, durability, and long-term reliability.
The unit is always checking for voltage, frequency, and power loss situations on both main and backup power sources.
Ensures that the two sources are not connected to the circuit at the same time and thus protects the operator's safety.
The emergency condition automatic switching is complemented with the manual switching for maintenance or inspection by the supported dual operation modes.
The LED lights offer an easy way to see the status of operation, fault, and source condition.
Input from the fire protection system is supported, thus enabling automatic switch off in the case of emergency.
The remote monitoring and system integration are enabled by a standard communication interface.

Switch Structure Explanation:
![]() |
1. Electric Key Lock: This feature allows controlling the internal power supply line of the switch. When the electric lock is open, the switch is operable automatically and remotely. When closed, the switch must be operated manually using the handle. 2. Operating Handle: For manual operation using the handle, closing the electric lock is a prerequisite, ensuring secure handling. 3. Mechanic Padlock: Before inspection, shift the switch to the '0' position using the handle. Then, engage the padlock mechanism and secure it with the padlock, preparing it for inspection. Engaging the padlock mechanism disrupts the internal power supply, preventing both electric and manual operations of the switch. 4. Position Indication: This indicates the operational state of the switch, displaying positions I, 0, and II, ensuring a clear understanding of its current state. |

Seamless Installation Method for Dual Power Automatic Transfer Switch (ATS):
● Perfect Installation Location:
Choose a dry and well-ventilated area that provides convenient access to both the primary and reserve power supply inlets. This strategic placement ensures effortless operation and maintenance.
● Precise Wiring Specifications:
Connect the primary and reserve power supplies meticulously to the ATS input terminal. Ensure the output terminal is linked to the load, maintaining a strict distinction in the phase sequence (L1/L2/L3/N/PE) for optimal performance.
● Efficient Switching Test:
Conduct a simulated main power failure once powered on, to verify the automatic switching time, which typically should not exceed 1.5 seconds. This guarantees uninterrupted power to the load.
● Stringent Safety Requirements:
Achieve reliable grounding with a shell protection level that corresponds to the environment, such as IP40 for indoor use. Ensure all installations comply with the GB/T 14048.11 standard for ultimate safety.
