English Introduction： The DW15-630 630/500A thermal AC380V undervoltage delay 3S molded case circuit breaker is an outstanding electrical device. It features a rated current of 630A and a breaking current of 500A, capable of meeting the high current demands in various industrial settings and providing reliable circuit protection. With an operating voltage of AC380V, it is well-suited to common industrial power supply environments. When the voltage drops abnormally, the undervoltage delay function of the circuit breaker is activated. After a 3-second delay, it will trip. This 3-second delay is designed to prevent false tripping due to momentary voltage fluctuations, giving the equipment and system a buffer time. It ensures that the circuit is only cut off when a true undervoltage fault occurs, effectively protecting electrical equipment from undervoltage damage and avoiding unnecessary production interruptions caused by frequent power cuts. Its thermal trip unit can accurately monitor and protect against overload currents based on the thermal effect of the current. When the current exceeds the rated value for an extended period, it will trip in a timely manner to cut off the circuit, preventing equipment damage and potential fire hazards caused by overloading, thus ensuring the safe and stable operation of the electrical system.
