中文版：
CDM3-125S/3300 125A插入式塑殼斷路器是一款專為低壓配電系統設計的高性能電路保護裝置。該產品采用模塊化結構設計，具備可靠的短路和過載保護功能，可廣泛應用于工業控制柜、建筑配電系統、設備電源回路等場景，為電力系統提供穩定的安全防護。
產品采用緊湊型外觀設計，寬度尺寸經過優化，有效節省安裝空間。125A額定電流規格可滿足常規負載需求，3300型配置提供三極斷路保護功能。觸頭系統采用特殊合金材料配合多重滅弧結構，顯著提升分斷能力。操作機構經過精密調試，確保合閘順暢且分閘響應敏捷。面板配備清晰可見的機械式分合閘指示器，便于運維人員快速掌握設備狀態。
插入式安裝設計是本產品的核心優勢，支持直接嵌入標準母線系統，實現快速安裝與更換。卡扣式固定結構設計有效減少接線工作量，維護時可通過簡單操作取出斷路器本體，大幅縮短停電時間。外殼采用高強度工程塑料一體成型，兼顧絕緣性能與結構強度，表面防腐蝕處理工藝可適應潮濕、粉塵等復雜環境。
為確保長期穩定運行，產品內置熱磁式脫扣機構，可根據負載電流變化實現精準保護。雙金屬片與電磁線圈的協同作用，既能應對持續過載電流，也能快速切斷突發短路故障。所有導電部件均經過鍍銀處理，有效降低接觸電阻，減少能量損耗。前端防護蓋板采用可拆卸設計，在不影響安全性的前提下方便接線操作。
建議定期檢查斷路器表面狀態及接線端緊固情況，保持通風散熱通道暢通。當指示器顯示脫扣狀態時，應先排除線路故障再進行復位操作。產品適用于交流50/60Hz、額定工作電壓至400V的配電網絡，建議由專業電工進行安裝調試。

The CDM3-125S/3300 125A plug-in molded case circuit breaker is a high-performance circuit protection device specifically designed for low-voltage distribution systems. Featuring modular construction and reliable short-circuit/overload protection functions, this product is widely applicable to industrial control cabinets, building power distribution systems, and equipment power circuits, delivering stable safety protection for electrical systems.
With its compact design optimized for space efficiency, the 125A rated current capacity meets general load requirements. The 3300 configuration provides three-pole circuit protection. The contact system employs special alloy materials combined with multi-arc extinguishing structures, significantly enhancing breaking capacity. Precision-adjusted operating mechanism ensures smooth closing and instantaneous trip response. The front panel features a visible mechanical status indicator for quick operational monitoring.
The plug-in installation design is a key advantage, allowing direct integration with standard busbar systems for rapid installation and replacement. The snap-fit mounting structure minimizes wiring work, enabling quick removal of the breaker body during maintenance to substantially reduce downtime. The enclosure utilizes high-strength engineering plastic with integrated molding technology, balancing insulation performance and structural integrity. Surface anti-corrosion treatment ensures reliable operation in humid or dusty environments.
Incorporating thermal-magnetic trip technology, the built-in protection mechanism provides accurate response to current variations. The bimetal strip and electromagnetic coil work in synergy to handle both sustained overloads and instantaneous short-circuit faults. All conductive components feature silver-plated contacts to reduce resistance and energy loss. The removable front cover facilitates wiring operations while maintaining safety standards.
Routine maintenance should include visual inspection of the breaker surface and terminal tightness, ensuring unobstructed ventilation. When the indicator shows tripped status, always eliminate circuit faults before resetting. Suitable for 50/60Hz AC networks with rated operational voltage up to 400V, professional electrician installation is recommended.
