產品英文介紹：
M6L-400L/3300 Molded Case Leakage Protection Circuit Breaker is a safety protection device specifically designed for low-voltage distribution systems. Featuring modular construction, this product operates in three-phase AC circuits up to 400V with a rated current of 250A, delivering reliable earth leakage protection alongside overload/short-circuit protection. Its optimized electromagnetic field distribution technology enables precise detection of ground fault currents ranging from 100mA to 500mA, with rapid circuit interruption based on preset thresholds to effectively mitigate electrical fire hazards and electric shock risks.
The device offers three adjustable leakage current settings (100mA/300mA/500mA), allowing flexible configuration according to specific safety requirements. The integrated intelligent processing module distinguishes transient interference from persistent leakage faults, maintaining high sensitivity while minimizing false tripping. Constructed with high-strength, heat-resistant housing and specialized arc-extinguishing chambers, it ensures thermal stability and reliable breaking capacity for continuous operation under high-load conditions.
Key technical features include: 1) Silver alloy welding process enhances conductivity and reduces energy loss; 2) Visual mechanical indicator for real-time status monitoring; 3) Dual reset mechanism supporting both manual testing and automatic recovery; 4) Compact design compatible with standard distribution cabinet installations. Typical applications extend to industrial production line distribution boxes, commercial building power control systems, and public utility supply networks requiring high-precision leakage protection, making it essential infrastructure for secure power system operations.
