Automatic Switching Appliance Q5 Series
Automatic Transfer Switch: ZSEE Q5 series is suitable for emergency power supply systems with an AC frequency of 50Hz, a rated operating voltage below 400V, and a rated current of 16-3200A, ensuring continuous power supply to electrical load circuits. The ZSEEQ5 is a specialized dual power product that can automatically detect the status of the power supply. When any phase of the power supply is found to be interrupted or has a voltage out of limit, it will switch the electrical load circuit from the faulty power source to another source. Once the power is restored to normal, the ATSE will automatically switch the load circuit back to the normal power source.
The product is mainly composed of three parts: a dedicated motorized double-throw transfer switch, an intelligent control system, and an independent arc-extinguishing system. The motorized double-throw switch acts as the “muscle” of the ATSE, used to switch on and off the power load circuit of the rated current and overload current; the intelligent control system serves as the “brain” of the ATSE, monitoring the quality of the power supply in real time and issuing switching commands. The switch contact system uses an independent arc guide device and a multi-channel arc extinguishing and burn-resistant silver-based contact to improve the ability to withstand short-term fault currents and load conversion closure capabilities.
Compliance Standards

Environmental Conditions and Applications
The ZSEEQ5 automatic transfer switch can operate reliably under the following conditions:
- The installation location altitude does not exceed 2000 meters;
- The ambient air temperature does not exceed +40°C, and its average temperature over 24 hours does not exceed +35°C, with a lower limit of no less than -5°C;
- At +40°C, the relative humidity of the air does not exceed 50%, and at lower temperatures, higher relative humidity is allowed, for example, up to 90% at 20°C. Special measures should be taken for condensation occasionally produced due to temperature changes;
- No explosive atmosphere environment;
- No rain or snow intrusion environment;
- Pollution level of 3;
- For special requirements, please contact the company.

Product Features
- Compact size and lightweight design save installation space and meet various customer requirements.
- Electromagnetic drive with instantaneous coil engagement completes the switching operation with higher reliability, faster speed, and ensures high synchronization.
- Fast switching speed with adjustable delay time for switching.
- Reliable electrical and robust mechanical interlocking ensure that only one power source is connected, preventing parallel operation of two power sources.
- The switch contact system uses an independent arc guiding device and a multi-channel arc extinguishing chamber with burn-resistant silver-based contacts, improving short-term resistance and load switching capabilities.
- Snap-type movable and stationary contact connection allows rapid separation, aiding in arc extinguishing.
- Silver-based contacts combine conductive, arc-resistant, and anti-corrosion properties.
Self-test Function
The self-test function allows periodic testing of the switch’s working status, ensuring good operational condition.
Memory Storage Function
The memory storage function records detailed conversion records of the dual power switch during previous use, making it convenient for users to compare fault records for line maintenance and repair.
Fault Alarm
The fault alarm provides alerts for power issues in the circuit, including power outages, overvoltage, undervoltage, phase imbalance, and frequency imbalance. It can monitor the power supply in real-time and report problems to on-site staff during use.
Reliable Contact and Arc Extinguishing Mechanism
The V-shaped staggered arc-extinguishing grid with silver-based contacts ensures the quality of current conduction and enhances the product’s connection and disconnection capabilities.
Three-position Products with Neutral Overlap Switching Function
3N Neutral Overlap Switching: During the switch’s power state transition, the N phase remains connected, avoiding a floating state. In the double-disconnection state, the N poles of both the primary and backup power supplies are closed. When the primary power supply is closed, the backup power N pole is disconnected; when the backup power supply is closed, the primary power N pole is disconnected.
