CDM6S-630L/4320B 500A Molded Case Circuit Protection Device Introduction
The CDM6S-630L/4320B 500A molded case circuit protection device is an intelligent electrical apparatus designed for modern power distribution systems, providing reliable circuit protection and energy management for low-voltage networks. Its modular construction ensures compatibility with diverse installation requirements in industrial plants, commercial complexes, and public infrastructure.
Equipped with an advanced bimetal thermal-magnetic trip mechanism and precision current sensing system, this device delivers dual protection functions: time-delayed overload protection and instantaneous short-circuit interruption. The 500A rated operational current capacity makes it ideal for main circuit protection in medium-scale power distribution systems. The 3P4L (4320B) configuration guarantees synchronous disconnection of phase and neutral conductors, enhancing operational safety.
The hybrid housing combines high-strength engineering plastics with a reinforced metal frame, integrating an independent arc-extinguishing chamber that significantly improves breaking capacity. The rotary operating handle features clear "ON/OFF" position indicators and a visible contact window, facilitating quick status monitoring. Standardized accessory interfaces allow flexible expansion with earth leakage protection and undervoltage release modules.
Through structural optimization, the compact design achieves approximately 18% volume reduction compared to similar products while maintaining excellent thermal dissipation. Silver-nickel alloy main contacts with specialized surface treatment effectively reduce contact resistance and extend electrical endurance. Removable terminal blocks accommodate conductor sizes from 35mm² to 240mm², meeting various wiring requirements.
This device operates reliably in wide temperature ranges from -25℃ to +70℃ with IP40 protection rating, suitable for demanding environments with humidity and dust contamination. Rigorous mechanical endurance testing verifies over 20,000 normal operational cycles. User-friendly external adjustment interfaces enable customized protection parameter settings based on specific load characteristics.
