CDM3L-125F/4300A 80A 1/3/5延2 Molded Case Leakage Circuit Breaker Product Introduction (English Version)
The CDM3L-125F/4300A 80A 1/3/5 DELAY2 molded case leakage circuit breaker is an intelligent protection device developed for low-voltage distribution systems. Featuring modular structure design, it operates effectively in AC power environments with 50Hz/60Hz frequency and rated voltage up to 400V. This integrated device combines overload protection, short-circuit protection, and earth leakage protection functions to enhance electrical safety and system reliability.
Equipped with a high-sensitivity electromagnetic leakage detection module, the breaker continuously monitors residual current in circuits. When ground fault current reaches predetermined thresholds, it initiates circuit interruption within 0.1 seconds to mitigate electric shock risks. The three-stage time-delay characteristic (1/3/5 DELAY2) offers configurable tripping coordination, allowing customized protection settings for different electrical load requirements.
Technical specifications include 80A rated current and 4300A breaking capacity, demonstrating robust performance under high fault current conditions. The compact molded housing integrates optimized internal components while maintaining operational reliability. Dual-break contact system combined with arc chute design ensures efficient arc extinction and extended electrical endurance.
This device finds applications in commercial buildings, industrial plants, and infrastructure projects, particularly suitable for motor control circuits, lighting distribution boards, and terminal equipment protection. User-friendly features include visible mechanical status indicators and test buttons for routine maintenance. The anti-loosening terminal design accommodates various conductor specifications.
Environmental adaptability is ensured through stable operation within -25℃ to +70℃ temperature range, meeting standard indoor installation requirements. The housing utilizes flame-retardant thermoplastic materials that comply with electrical safety guidelines. Enhanced electromagnetic compatibility design minimizes operational interference to peripheral equipment.
Structural advantages include maintenance-free operation and tool-free accessory installation. The product incorporates thermal-magnetic trip mechanism for precise overload protection coordination. Transparent protective covers on terminals improve installation safety. Through rigorous quality verification processes, the breaker demonstrates consistent performance in diverse electrical environments.
