CDM3L-125C/4310B Molded Case Leakage Protection Circuit Breaker Introduction
The CDM3L-125C/4310B molded case leakage protection circuit breaker is a safety protection device specifically designed for low-voltage distribution systems, suitable for circuits with rated current of 125A and control voltage of DC24V. Integrating circuit switching control, overload protection, short-circuit protection, and leakage detection functions, this product adopts modular structural design to effectively enhance the safety and operational stability of power distribution systems. Its compact molded case structure ensures protective performance while considering installation convenience and space utilization, making it suitable for various electrical protection requirements in industrial, commercial, and infrastructure applications.
The core unit features sensitive electromagnetic leakage detection mechanism that continuously monitors abnormal current fluctuations in circuits. When leakage current exceeds preset thresholds, the system automatically interrupts the circuit within 0.1 seconds, effectively reducing electric shock risks and fire hazards. The trip mechanism utilizes wear-resistant alloy materials combined with precision mechanical transmission design, maintaining stable operation characteristics even under frequent switching conditions. Oxidation-resistant terminal contacts support reliable connection for conductors up to 25mm², accommodating different wire specifications.
This circuit breaker supports horizontal or vertical mounting with IP40 protection rating, operating stably in ambient temperatures from -25℃ to +70℃. The clearly marked handle position indicator enables quick status identification for maintenance personnel. Rigorous factory testing verifies product reliability, while silver-alloy contacts reduce resistance and extend electrical service life. Ideal for motor control systems, distribution cabinets, and lighting circuits requiring leakage protection, it provides graded protection for electrical equipment.
