在安全防護層面，該斷路器配備可視分合閘指示與機械聯(lián)鎖裝置，避免誤操作風險。觸頭狀態(tài)可通過外部觀察窗實時監(jiān)測，維護人員無需打開外殼即可完成常規(guī)檢查。針對不同應(yīng)用場景，產(chǎn)品提供多種脫扣特性曲線選擇，用戶可根據(jù)實際負載特性靈活配置保護參數(shù)，實現(xiàn)精準的電流分級保護。
CDM3-630F/43002A 500A Molded Case Circuit Breaker Product Introduction (English)
The CDM3-630F/43002A 500A molded case circuit breaker is a low-voltage electrical protection device designed for power distribution systems, suitable for AC 50Hz/60Hz networks with rated operational voltage up to 690V. Featuring modular construction, this product integrates long-delay overload protection and instantaneous short-circuit protection, providing reliable line management and fault prevention for industrial power distribution, building electrical systems, and infrastructure applications.
This breaker demonstrates three core technical strengths: Firstly, optimized electromagnetic system and contact structure design significantly enhance breaking capacity and electrical durability. Secondly, the independent arc extinguishing chamber with composite insulation materials ensures reliable interruption under complex operating conditions. Thirdly, the precision operating mechanism with multi-stage linkage provides clear switching feedback while supporting accessory expansion for remote monitoring functions.
The enclosure utilizes high-strength engineering plastics through integrated molding technology, achieving excellent insulation and mechanical robustness. The conductive path adopts multi-layer silver-plated composite technology to minimize contact resistance, complemented by innovative thermal dissipation channels that maintain stable temperature rise during continuous full-load operation. Installation flexibility is provided through both fixed and plug-in versions, supporting backplate mounting and standard 35mm rail systems for efficient field deployment.
Safety features include visible switching status indicators and mechanical interlock devices to prevent misoperation. Contact conditions can be monitored through external inspection windows without disassembling the housing. Multiple tripping characteristic curves are available for precise current coordination protection, allowing users to customize protection parameters according to specific load requirements. The product s compact design and standardized dimensions ensure compatibility with mainstream electrical cabinets while optimizing space utilization in control panels.
