CDM6S-630M/4338B Molded Case Circuit Protection Device Introduction
The CDM6S-630M/4338B molded case circuit protection device is a core electrical equipment designed for low-voltage distribution systems. Featuring modular design concepts and optimized structural engineering, it provides reliable overload and short-circuit protection for circuits up to 630A. The housing combines high-strength engineering plastics with flame-retardant materials, delivering excellent insulation performance and mechanical durability to ensure stable operation under complex working conditions.
At its functional core, the device integrates an intelligent trip mechanism with precisely calibrated thermal-magnetic protection system, enabling rapid identification of circuit abnormalities and prompt disconnection. The three-level linkage contact structure paired with silver alloy contact materials effectively reduces contact resistance while enhancing conductivity efficiency and extending electrical service life. Unique airflow channel design accelerates arc-extinguishing medium diffusion, maintaining stable arc suppression performance even at 6kA breaking capacity to ensure operator safety. The product supports 3-pole/4-pole configurations, adaptable to various power distribution network architectures including TN and TT systems.
This device is suitable for installation in distribution boxes and cabinets across industrial plants, commercial buildings, and infrastructure projects, providing graded protection for motors, transformers, and main circuits. Compact dimensions facilitate DIN rail mounting, with clearly marked ON/OFF position indicators on the operating handle and transparent protective cover preventing accidental contact. Maintenance personnel can observe internal status through viewing windows, supporting rapid module replacement without affecting overall system operation. Rigorous environmental adaptability testing verifies stable performance within temperature ranges of -25°C to +70°C and 95% relative humidity.
