Moulded Case Leakage Protection Circuit Breaker M6L-100L/4300A 50A 30/100/500MA 0S U Product Introduction
The M6L-100L/4300A 50A moulded case leakage protection circuit breaker is an intelligent protective device specifically designed for low-voltage distribution systems. Suitable for AC 50Hz circuits with rated voltage up to 400V, this integrated solution combines circuit protection and earth leakage protection functions, providing rapid response to overload, short circuit, and leakage faults to enhance electrical safety and system reliability.
Featuring modular construction with an intuitive operation interface and precision adjustment mechanisms, the 50A rated current model adapts to conventional industrial and commercial power load requirements. The selectable leakage tripping thresholds (30mA/100mA/500mA) cater to diverse application scenarios: 30mA level prioritizes personal shock protection, 100mA level focuses on equipment protection, while 500mA setting serves as fire prevention safeguard. Instantaneous tripping characteristic (0S) ensures rapid circuit interruption upon fault detection, significantly reducing electrical hazard risks.
Manufactured with high-strength engineering plastics, the enclosure demonstrates excellent insulation and mechanical durability. The contact system utilizes special alloy materials combined with optimized arc-extinguishing structure, achieving 4300A breaking capacity. The integrated thermal-magnetic trip mechanism coordinates with electronic leakage detection module to deliver dual protection synergy. Flexible installation options include DIN rail mounting or bolt fixing, accommodating various panel layouts.
This device is ideal for residential buildings, commercial complexes, and industrial plants, providing reliable protection for motors, distribution boxes, lighting circuits and other electrical installations. Through proper parameter configuration, it can function independently as terminal protection or collaborate with upstream breakers to establish hierarchical protection systems.
