【中文版】
產(chǎn)品概述：
DZ20Y-400T/3330塑殼斷路器是一款專為低壓配電系統(tǒng)設(shè)計的高性能電氣保護(hù)裝置，采用創(chuàng)新透明殼體結(jié)構(gòu)和集成化排線設(shè)計。產(chǎn)品額定電流400A，工作電壓AC220V，適用于工業(yè)配電、商業(yè)建筑及公共設(shè)施的電力分配與控制場景。其緊湊型結(jié)構(gòu)在保證功能完整性的同時，兼顧了安裝便捷性與運維可視化需求。
核心設(shè)計特點：
-
透明觀察窗口
殼體頂部配置高透光工程材料視窗，可直觀查看內(nèi)部觸頭狀態(tài)與分合閘指示，便于快速判斷設(shè)備運行狀態(tài)，降低巡檢維護(hù)難度。
-
集成式接線系統(tǒng)
內(nèi)置優(yōu)化設(shè)計的銅排連接結(jié)構(gòu)，支持多線纜并行接入。模塊化插接端子實現(xiàn)快速配線，有效縮短安裝工時，尤其適應(yīng)密集型配電柜的布線需求。
-
精準(zhǔn)保護(hù)機制
配備三段式保護(hù)特性（過載長延時、短路短延時及瞬時保護(hù)），通過精確的電磁-熱雙脫扣系統(tǒng)實現(xiàn)對線路的全面防護(hù)。動作特性曲線經(jīng)過嚴(yán)格驗證，確保在各類負(fù)載條件下穩(wěn)定運行。
-
環(huán)境適應(yīng)能力
殼體采用耐高溫、抗沖擊復(fù)合材料，可耐受-25℃至+70℃工作環(huán)境。內(nèi)部元件經(jīng)特殊防塵處理，適用于粉塵、潮濕等復(fù)雜工況環(huán)境。
典型應(yīng)用場景：
• 制造工廠動力配電柜主開關(guān)
• 商業(yè)綜合體樓層配電箱
• 光伏發(fā)電系統(tǒng)直流側(cè)保護(hù)
• 軌道交通站場供電系統(tǒng)
使用建議：
建議定期通過透明窗口進(jìn)行目視檢查，及時清除表面浮塵。連接排緊固件推薦每2000操作次或每年進(jìn)行扭矩校驗（具體以實際使用強度為準(zhǔn)）。
【English Version】
Product Overview：
The DZ20Y-400T/3330 400A AC220V Molded Case Circuit Breaker is a high-performance electrical protection device specifically engineered for low-voltage distribution systems. Featuring an innovative transparent housing and integrated busbar design, this 400A rated device operates at AC220V, making it suitable for power distribution and control in industrial plants, commercial buildings, and public infrastructure applications. Its compact construction ensures functional integrity while optimizing installation efficiency and operational visibility.
Key Design Features：
-
Transparent Inspection Window
The top-mounted viewing window made of high-transparency engineering polymer allows visual confirmation of contact status and switching position indication, significantly simplifying equipment condition monitoring and maintenance procedures.
-
Integrated Connection System
Optimized copper busbar structure supports parallel cable termination. Modular plug-in terminals enable rapid wiring, particularly beneficial for high-density panel installations.
-
Precision Protection Mechanism
Three-stage protection characteristics (overload long-time delay, short-circuit short-time delay and instantaneous trip) are achieved through a calibrated electro-thermal magnetic tripping system. Verified tripping curves ensure reliable operation across diverse load conditions.
-
Environmental Durability
High-impact resistant housing material withstands operating temperatures from -25℃ to +70℃. Internal components with dust-proof treatment maintain performance in challenging environments including dusty or humid locations.
Typical Applications：
• Main switchgear in manufacturing plant power distribution cabinets
• Floor distribution boxes of commercial complexes
• DC side protection in photovoltaic systems
• Power supply systems for rail transit stations
Usage Recommendations：
Regular visual inspection through the transparent window is advised. Busbar fasteners should undergo torque verification every 2,000 operations or annually (subject to actual service conditions).
