塑殼漏電保護斷路器DZ20L-400T/4300 250A 50MA 延時0.2S 透明
產品介紹
中文介紹： DZ20L-400T/4300 250A 50mA 延時0.2S 透明塑殼漏電保護斷路器是一種高性能的電氣保護設備，廣泛應用于工業和民用配電系統中。該產品采用透明外殼設計，便于觀察內部結構和運行狀態，同時具備漏電保護功能，能夠在檢測到漏電電流達到50mA時，延時0.2秒自動切斷電源，有效保障人身和設備安全。
該斷路器的額定電流為250A，殼架電流為400A，適用于多種電壓等級的配電系統。其漏電保護功能基于電子式漏電檢測技術，通過零序電流互感器檢測漏電信號，并由電子組件板放大后觸發脫扣器動作，切斷電源。此外，該產品還具備過載和短路保護功能，能夠有效防止因過載或短路引起的設備損壞。
透明外殼設計不僅美觀，還便于安裝和維護人員快速檢查設備狀態，提高工作效率。這種斷路器適用于需要高可靠性和高安全性的場合，如商業建筑、工業廠房和居民住宅等，是現代配電系統中不可或缺的安全保護裝置。
English Introduction: The DZ20L-400T/4300 250A 50mA Delay 0.2S Transparent Plastic Enclosure Leakage Protection Circuit Breaker is a high-performance electrical protection device widely used in industrial and residential power distribution systems. This product features a transparent enclosure, which facilitates observation of the internal structure and operational status. It also has a leakage protection function that can automatically cut off the power supply after a 0.2-second delay when the leakage current reaches 50mA, effectively safeguarding personal and equipment safety.
The circuit breaker has a rated current of 250A and a frame current of 400A, making it suitable for various voltage-level power distribution systems. Its leakage protection function is based on electronic leakage detection technology. The zero-sequence current transformer detects leakage signals, which are then amplified by the electronic component board to trigger the tripping mechanism and cut off the power. In addition, the device also provides overload and short-circuit protection, effectively preventing equipment damage caused by overloads or short circuits.
The transparent enclosure design is not only aesthetically pleasing but also allows installation and maintenance personnel to quickly inspect the device s condition, improving work efficiency. This type of circuit breaker is suitable for applications that require high reliability and safety, such as commercial buildings, industrial plants, and residential homes. It is an essential safety protection device in modern power distribution systems.
