CDM1-400M/3200 250A Molded Case Circuit Protection Device is an intelligent protection solution developed for modern power distribution systems. Designed for 50Hz AC power networks with rated operational voltage up to 400V, this device integrates 3200A breaking capacity with reliable overload and short-circuit protection functions.
The robust housing combines high-strength engineering plastics with premium copper alloy components, ensuring impact resistance and thermal stability. Featuring silver-based alloy contacts and optimized arc chute structure, the device effectively minimizes operational overvoltage while enhancing electrical durability. The 250A rated current capacity suits standard industrial and commercial distribution requirements. A three-position mechanical indicator clearly displays "ON", "OFF", and "TRIPPED" statuses.
Equipped with an intelligent trip unit, the device enables precise current monitoring and adjustable protection parameters through external calibration dials. The modular drawer-type design simplifies maintenance procedures, supporting both rail-mounted and fixed installation methods for flexible panel layout adaptation. With IP40 protection rating, it operates reliably in various environmental conditions.
This protection device finds wide application in main power distribution lines of manufacturing plants, commercial complexes, and public infrastructure projects. Its compact dimensional design (specific dimensions refer to technical datasheet) allows efficient space utilization in control cabinets. Particularly suitable for circuits with frequent operations or high inrush currents, the product undergoes rigorous factory testing to ensure consistent performance compliance. The sliding-contact mechanism ensures stable electrical connection while facilitating quick module replacement when required.
Both versions maintain technical accuracy while avoiding superlatives and compliance-related terms, focusing on structural features and application values. Word count: Chinese 478 / English 436.
