ZSEEQ4-160~630(CB) Series

Automatic Transfer Switching Device

Product Overview

The ZSEEQ4 series automatic transfer switching device (ATSE) is suitable for dual power systems with an AC frequency of 50Hz, a rated operational voltage of 380V, and a rated current of 80A to 630A. It can switch between the primary power source (Power I) and the backup power source (Power II). This switch utilizes 3-pole or 4-pole circuit breakers (MCCB) as the main operating body, accompanied by an electromechanical operator with mechanical interlock. It is suitable for critical power supply environments where power outages are not allowed, ensuring the continuity of power supply to important loads through reliable switching between primary and backup power sources.
