塑殼斷路器CDM1-63M/4300 50A
產品概述
CDM1-63M/4300 50A塑殼斷路器是一款采用先進技術設計的三相四極配電保護裝置，適用于額定電流50A的電路控制與保護。該產品采用高強度絕緣材料外殼，具有結構緊湊、分斷能力優異的特點，能有效切斷過載及短路電流，保障電氣設備和線路安全穩定運行。其四極設計（3P+N）可滿足三相四線制系統的配電需求，中性極與主極同步分合，確保電路隔離的可靠性。1816
核心功能
該斷路器具備過載和短路雙重保護功能，通過熱磁式脫扣機構實現精準動作。當線路電流超過設定閾值時，電磁脫扣單元可快速響應（短路保護），而雙金屬片延時脫扣機制則針對過載電流提供保護。飛弧距離短的設計降低了安裝空間要求，同時支持垂直或水平安裝方式，適應不同配電柜布局需求。產品操作方式為手動直接控制，分合閘狀態清晰可見，便于日常維護與故障排查。71517
技術特性
CDM1-63M/4300系列采用模塊化結構，額定工作電壓可達690V，適用于50Hz/60Hz交流配電網絡。50A規格的脫扣器電流可調，允許根據實際負載情況靈活配置保護參數。產品內部觸頭系統采用銀合金材料，接觸電阻低且耐電弧侵蝕，顯著延長電氣壽命。外殼具備IP20防護等級，能有效防止直徑大于12.5mm的固體異物侵入，適合工業環境使用。41223
Product Overview
The CDM1-63M/4300 50A molded case circuit breaker is a three-phase four-pole protection device designed for 50A rated current applications. Featuring a robust insulated housing and optimized arc quenching system, it ensures reliable interruption of overload and short-circuit currents in 400V/690V AC distribution systems. The 3P+N configuration provides complete circuit isolation with synchronized neutral pole operation, making it ideal for TN-S or TT earthing systems.18
Key Features
This breaker integrates thermal-magnetic trip technology, where the instantaneous magnetic trip responds to short circuits while the bimetallic strip delivers time-delayed protection against overloads. The compact design achieves minimal arc extension (below 50mm), allowing high-density panel installation. Manual operation handle indicates clear ON/OFF position with positive mechanical latching. The product supports both DIN rail and fixed mounting options, with copper alloy terminals ensuring stable conductivity under varying temperature conditions.717
Technical Specifications
Rated for 50Hz/60Hz power networks, this unit maintains consistent performance across -5°C to +40°C ambient temperatures. The 50A current rating derives from precision-calibrated tripping curves (10kA breaking capacity) suitable for motor feeders or distribution sub-circuits. Silver-nickel main contacts provide low contact resistance (<50μΩ) with self-cleaning surfaces that reduce contact welding risks. External accessories include auxiliary contacts and shunt trip modules for extended control functionality without compromising main body dimensions.41523
