AC Isolation Switch: ZSEE G4 series is developed and designed with a modular concept. The switch body is assembled using dedicated modules and a new exterior design, reducing the exposure of metal components and improving operational safety.

Automatic Transfer Switch: ZSEE KU series, suitable for emergency power supply systems with an AC rated working voltage of AC400V or below, rated frequency of 50/60Hz, and rated current of 16A to 630A, for automatic transfer between two power sources to ensure continuous, safe, and reliable operation of critical loads (such as fire protection loads).

Automatic Transfer Switching Device: ZSEE Q4 series (ATSE) is a new generation of ATSE products developed and designed by our company. This series is suitable for distribution systems with an AC frequency of 50Hz, a rated operational voltage of 400V, and a rated current of 16 to 100A.

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.

Automatic Transfer Switch: ZSEE KE-L series is suitable for AC power distribution systems with a frequency of 50Hz, a rated current of 16~630A, and a rated operating voltage of AC230V/400V. It can perform the transfer between regular and backup power sources and is used in critical applications within power systems where power interruptions are not permissible.

Automatic Transfer Switch: ZSEE KE series is suitable for AC 50Hz, with a rated current of 16~630A and a rated operating voltage of AC400V in power distribution systems. It can handle the transfer between the main power supply and backup power, making it suitable for important power systems where power outages are not permitted.

Automatic and Electric Transfer Switch: ZSEE Q series integrates switching and logic control, requiring no external controller to achieve electromechanical automation. It features voltage detection, frequency detection, communication interface, fire feedback, electrical and mechanical interlocks, and can perform automatic, electric remote, and emergency manual control.

Mechanical Emergency Pump Start Device: ZSEE C1 series is a mechanical emergency pump start product based on a contactor as the main component, designed and developed specifically for fire water supply systems with a manual forced start function.

Control and Protection Switchgear: ZSEE KB1 series is designed based on the requirements of the smart grid, integrating the main functions of separate components such as circuit breakers, contactors, overload relays, isolating switches, and current-voltage meters into a modular single structure.

DC Molded Case Circuit Breaker: ZSEE M3Z series is a DC product series launched by our company, suitable for low-voltage distribution networks with a rated operating voltage of DC1000V, DC1500V, and a rated operating current of 63-500A.
