框架斷路器DW15-630 630/500A熱式AC380V欠壓延時3S
中文介紹： DW15-630 630/500A熱式 AC380V 欠壓延時 3S 框架斷路器是一種性能卓越的電氣設備。它具備 630A 的額定電流，可承受 500A 的分斷電流，能夠滿足多種工業場景下的大電流需求，為電路提供可靠的保護。其工作電壓為 AC380V，適應常見的工業用電環境。當電壓出現異常下降時，該斷路器的欠壓延時功能會啟動，經過 3 秒延時后動作，這 3 秒延時是為了避免因瞬間電壓波動而誤動作，給設備和系統一個緩沖時間，確保只有在真正出現欠壓故障時才切斷電路，有效保護用電設備免受欠壓損壞，同時避免了因頻繁斷電對生產流程造成的不必要干擾。其熱式脫扣器能夠根據電流的熱效應原理，對過載電流進行精準監測和保護，當電流長時間超過額定值時，能夠及時動作，切斷電路，防止因過載導致的設備損壞和火災等安全隱患，保障電路系統的安全穩定運行。
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.
