CDM3L-400F/4300A 350A U 1/3/5 AC230V Molded Case Leakage Protection Circuit Breaker Product Introduction (English)
The CDM3L-400F/4300A 350A U series molded case leakage protection circuit breaker integrates overload, short-circuit, and leakage protection functions, designed for 230V AC low-voltage distribution systems. With modular design philosophy, it offers 1-pole, 3-pole and 5-pole configurations to flexibly meet installation requirements in industrial control cabinets, commercial distribution boxes, and residential electrical systems.
Equipped with precision electromagnetic trip mechanism and electronic leakage detection module, the device can detect leakage currents exceeding 30mA within 0.1 seconds and promptly interrupt faulty circuits. The 350A rated current capacity ensures reliable operation under high-load conditions, while its breaking capacity meets industry-standard requirements for effective equipment and personnel protection.
The enclosure adopts high-strength engineering plastic molding technology with IP40 protection rating. The multi-layer metal partition arc chamber effectively extinguishes short-circuit arcs. The three-position status indicator window clearly displays "OFF", "ON", and "TRIPPED" states, facilitating quick operational diagnostics.
Electrical parameters include an operational temperature range of -25℃ to +70℃, ensuring stable performance in diverse environments. The mechanism achieves 20,000 mechanical operation cycles, with silver-alloy contacts ensuring long-term conductivity reliability. Standard 35mm DIN rail mounting simplifies panel assembly and system upgrades.
This product combines structural durability with intelligent protection features, providing comprehensive circuit monitoring for power distribution networks. Its compact dimensions and visual status indicators optimize space utilization in control panels while enhancing maintenance efficiency. The design prioritizes user safety through rapid fault response and reliable electrical isolation capabilities.
